One would be hard put to think of an economic activity so efficient that it generated no residue of any kind. And if one does come up with such an activity -- say, a teacher speaking to his students, or a musician performing for his audience -- it must be narrowly defined, and, in all probability, the support systems of the teacher, the musician, and their congregations must be ignored. The teacher must speak with no notes, the musician perform with instruments having a long life -expectancy. Needless to say, the audience cannot be permitted to litter, not even their ticket stubs. In short, the economic activity must be of short duration and have few people involved.
Societies do not grow this way; civilizations do not rise without waste products. (Even more so are they incapable of declining without creating trash. )
Given the fact of solid wastes, then, society's question must be what to do with them. Primitive communities use next to everything. There is little they produce that cannot be burned for heat or plowed into the ground when it has no more use. If a knife blade is brought in from afar, it will be honed and honed again until only its rust is left to be returned to the earth.
We do not live in such a place.
As citizens of the most technologically advanced nation in history, we import goods and materials from every corner of our world. The United States is so wealthy that our discards are seized by other peoples. Scrap iron and waste paper are shipped from our ports to become the inputs of industries thousands of miles away. We think our land so rich that we export sewage sludge to become fertilizer on other continents.
In recent years this attitude has been changing. Some observers have named Earth Day as the turning point; others cite the oil embargo of the winter of 1973-74. One event brought the issue to the publics consciousness, the other emphasized the need for alternative fuel sources, and permanently changed the economics of energy recovery from solid waste. During the same period pilot plants and demonstration projects were showing that the technology for reclaiming materials and energy from trash existed, even if not quite perfected.
The first three chapters of this collection may be considered as basic background an the issue and on the Federal role. Chapter IV deals mainly with the technology and its problems, and Chapter V with the institutional constraints encountered in an economy oriented to virgin material use. The last chapter is on current research, hazardous wastes, and sewage sludge. For the reader who wishes to be selective in his approach the following summary will provide a guide.
The introductory selections of Chapter I take a statistical look at solid waste and discuss the benefits of resource recovery. The chart that is item 1 simply points out that the quantity of trash grows as economic development rises. The second selection presents data on and interpretation of the quantity and composition of solid wastes. For 1973 total post-consumer municipal wastes amounted to 135 million tons, a per capita rate of 3.5 pounds per day. Overall, only about 7 percent was recycled, and of this amount 93 percent was paper. It is projected that by 1990 municipal wastes will be generated at the rate of 225 million tons annually, and 26 percent (58 million tons) will be recovered. The projections are particularly uncertain due to present conditions of rising material and energy prices and changing international bargaining relationships.
Item 3, the benefits of resource recovery and waste reduction, discusses impacts on local waste management. the conservation of natural resources. and environmental protection. With municipal collection and disposal costs expected to double in the 1974-85 decade, alternative methods will be sought. Resource. recovery eases the pres ure on landfill sites by reducing the quantity of residue by as much as 95 percent, and it permits the closing of incinerators which, as a group, have a poor air pollutant control record.- dangers of leachate from open dumps and landfills contaminating ground and surface waters are likewise reduced. Increasing pressure on the world's natural resource base is already being felt and is anticipated to increase over time. The post-consumer waste stream could provide between 6 and I I percent of current annual U.S. production of various major metals, up to 20 percent of paper, and between I and 2 percent of energy requirements. This also has implications for the international balance of trade, and supply from foreign sources in the face of instances of nationalization and organization of cartels. Lastly, while it is difficult to quantify and analyze, the preservation and improvement of environmental quality represents a third set of problems for which resource recovery and waste reduction can contribute some measure of solution.
Chapter H describes the requirements, primarily research and development. of the Solid Waste Disposal Act and the Resource Recovery Act of 1970. The text of the amended law appears as item 5.
The legislation gave the Environmental Protection Agency and the Bureau of Mines the prime Federal responsibility. Their programs are dealt with in Chapter III. Within EPA, the designated organization is the
Office of Solid Waste Management Programs (OSWMP), which issued its Solid Waste Management Strategy (item 6) in October, 1974. The strategy identifies the major issue as one of improper waste management, resulting in problems ranging from extreme health and environmental damages to resource wastage. The primary reason is that improper disposal is cheap compared to environentally acceptable practices. OSWMP's program has two goals, the first being environental protection, with particular emphasis on preparing for a hazardous waste regulatory role. It is anticipated that the States will play a large part, and a principal objective is to strengthen their ability to do so, both administratively and legislatively by establishing authority over the disposal of allwastes. The second goal is resource conservation, with particular attention to energy recovery from mixed urban wastes. Other objectives are to promote materials recovery, to conduct studies on source reduction, and to encourage the consumption of secondary materials through Federal procurement and other actions.
An excerpt from OSWMP's annual report for fiscal year 1975 is item 7. The Hazardous Waste Management Division is establishing a data base, and conducting major studies in 13 industry groupings to define quantitatively and qualitatively their hazardous waste streams. It is also developing the tools and capabilities to regulate hazardous wastes, and is assisting the States to dothe same. Major program elements of the Systems Management Division are technical assistance to municipalities, and research into land disposal and special wastes. During FY 1975 an increased effort was made at understanding the effects of disposing sewage sludge on land. The Resource Recovery Division manages five large demonstration pro-
jects, and conducts studies and analyses to determine means of increasing the demand for secondary materials. In addition, it is responsible for developing the guidelines on resource recovery mandated by law.
Next, thedirector of theBureau of Mines describes recent activities of his organization, including the development of two processes for materials recovery, one from incinerator residues, the other from raw refuse. The Bureau has also worked on better methods of processing junked autos. His testimony contains several interesting charts on quantities of new minerals required each year, amounts imported and exported, and their costs.
Chapter IV examines the potential for resource recovery and looks at several projects and the problems they have encountered. In the first selection (item 9) EPA estimates that 900 trillion Btu' s were available in the municipal refuse of the Standard Metropolitan Statistical Areas in 1973. This is equal to the amount of energy in 154 million barrels of oil; other equivalents are 10 percent of all the coal consumed by utilities in 1973, and 28 percent of the oil projected to be delivered through the Alaskan pipeline. Based on current plains, it is projected that by 1980 almost 30 cities and counties will be operating the equivalent of about thirty-six 1, 000 ton/day plants recovering 85 trillion Btu's per year. The agency notes that at present the only technologies that can be considered "commercially available" are the generation of steam in waterfall incinerators fueled solely by unprocessed wastes, and the use of prepared solid waste as a supplement to pulverized coal in electric utility boilers.
Item 10 reviews the markets for recycled materials during a recent period of severe fluctuation and discusses some of the market factors involved. The next piece could be described as a businessman's look at
68-863 0 76 2
the resource recovery industry. Problems encountered by the different companies marketing recovery systems are noted, and the positive side of the slow implementation of resource recovery is pointed out: a rash of cities selling reclaimed materials would glut the market and prices would fall drastically; and, with many of the systems unproven at full-scale, there would be failures that would not only be expensive, but would deter other cities considering resource recovery.
The technology and economics of six resource recovery demonstrations supported by EPA are described in item 12. The six demonstrations are
(1) the use of shredded, classified waste as a coal substitute in St. Louis;
(2) pyrolysis to produce a gaseous fuel for steam generation in Baltimore;
(3) pyrolysis to produce a liquid fuel in San Diego County; (4) the use of processed waste as a fuel oil substitute in Delaware; (5) the wet pulping of waste for materials recovery in Franklin, Ohio; and (6) the recovery of materials from incinerator residue in Lowell, Massachusetts. The Lowell project was cancelled when it was discovered that the incinerator could not meet air pollution standards without very expensive capital improvements.
The St. Louis demonstration, in particular, has received wide attention in the press and has been the model for a number of other cities contemplating similar projects. The Union Electric Co.. in whose boilers the waste was fired, subsequently announced plans to build additional processing facilities in order to use the entire waste output of the St. Louis metropolitan area. Problems have been encountered, however, with air pollution, ash removal, and possible health hazards as described in item 13.
The Delaware project has not yet been constructed, but it has already been the subject of controversy. At first rejected by EPA for a demonstration grant, and later approved, the project required a change in scope. The General Accounting Office questioned the usefulness of the demonstration. Their review of the facts and EPA's reply are presented in item 14.
The CPU-400 project is an innovative research and development effort that has encountered a number of technical problems. The waste is burned in a pressurized fluid bed incinerator, and the gases are used to turn a turbine which moves an electrical generator. Particles in the gases, however, eroded the blades of the turbine. The problem was to clean the gas without reducing the pressure to such an extent that it could not turn the turbine. An executive from the contracting Combustion Power Company discussed the difficulties in hearings held in March 1974 (item 15).
The next two articles present the bright and cloudy sides of the Nashville Thermal Transfer Corp. Established as a nonprofit corporation, it was financed by a bond issue and received no Federal assistance. Air pollution and other technical problems have caused financial predicaments both for the company and their private customers.
Items 18 and 19 deal with the recovery of methane gas from sanitary landfills. While this method offers no solution to the waste disposal problem of cities, its comparatively low cost makes it an attractive minor energy source. The methane, along with other gases and water, is produced naturally as the garbage in the landfill decomposes. Wells are drilled, and the gas is captured and purified. Projects in Palos Verdes, California, and Mountain View, California are described.
The last article in this chapter argues against the high technology systems like those reviewed above. If individual households spent 6 minutes a week separating their trash, the author states, a $100, 000 plant could do the job of a multi-million dollar facility.
The problems discussed in Chapter IV were primarily technological. Chapter V deals with obstacles in existing law and institutional arrangements, and the availability of capital. Item 21 considers the role that the Federal procurement process can play in creating demand for products containing recycled material. While the U. S. Government is a large consumer of many products, its purchases represent only a smanpercentage of national output. At least as important as the direct impact, though, is the fact that Federal procurement specifications are widely copied by State and local governments and some industries. Three Federal recycling programs are also reviewed: the General Services Administration's procurement of recycled paper, the army's tire retreading program, and the Joint Committee on Printing's use of secondary fibers in printing and publishing papers.
Item 22 is actually a continuation of the previous excerpt and deals with the tax benefits available to producers of virgin materials. Inasmuch as they do not apply to secondary materials industries they constitute a subsidyfor virgin materials. The tax benefits are depletion allowances, the ability to deduct from current income certain development costs (expensing of capital expenditures), capital gains treatment, and several foreign tax allowances. EPA conducted an analysis of virgin materials which compete with material that could be recycled from solid waste. Covered were timber, oil, gas, coal, iron ore, primary aluminum, and glass sand
for the year 1970. The tax benefits to these industries came to over $2 billion, of which $1. 8 billion was for petroleum and natural gas. The situation has changed completely since the passage of P. L. 94-12 in 1975, which repealed, with some exceptions, the depletion allowance on oil and gas.
Another institutional factor affected by recent legislation is the topic of discriminatory freight rates. Scrap materials are subject to higher, purportedly discriminatory, rates than virgin ores with which they compete. The Railroad Revitalization and Regulatory Reform Act which was signed into law in February, 1976, should lead to an end to this problem. The new law calls for an investigation of the rate structure and establishes procedures for eliminating any unjust or unreasonable rate differentials between new and recycled materials.
Item 23 discusses several constraints to implementation of energy recovery systems. Technical and market uncertainties present a chicken and egg situation: risks exist because the systems have not operated successfully for long periods of time, but the risks will be reduced only after a number of cities and companies have taken a chance and accumulated operating data. Lack of information and failure to engage in adequate planning by municipalities is another difficulty because of the complicated nature of the endeavor and because so many of the variables are dependent on the local situation. And, there are a variety of State laws, such as those restricting contract length and requiring competitive bidding, that jeopardize resource recovery systems. In the last part of this piece EPA considers the availability of financing, and concludes that, while there may belsome difficulties, no major shortage of capital is anticipated.
The next two articles also deal with financing. The authors of number 24 are with a major investment bank and discuss alternative approaches, and risk-sharing options. Item 25 analyzes the recently revised Internal Revenue Service regulations permitting tax-exempt financing of solid waste management resource recovery facilities.
Finally, item 26 is a report from the Wall Street Journal on the bonds issued for the Saugus, Massachusetts plant that will generate and sell steam.
Two views from academia open Chapter VI. Item 27 recounts the areas in which university research in solid waste management is being carried out. Effects of land disposal, and particularly the leachate problem, have engendered a great deal of interest, as have the biological processes involving such things as methane and ethanol production. Two other areas mentioned are sludge disposal and the application of systems analysis to solid waste management. The author closes with a plea for support for the training of personnel. Item 28 concentrates on several projects directed at the recovery of consumer wastes. The author reports on cryogenic treatment of automobile tires, the separation of nonferrous scrap by induction. the hydrolysis of refuse to produce ethyl alcohol, and computer-based mechanical sorting of municipal solid waste.
The next piece is an excerpt of an article on anaerobic digestion. Like drilling wells in sanitary landfills, which was dealt with in Chapter IV, the product recovered is methane gas. The difference is that the natural degradation process is speeded up by controlling the temperature and other variables in a mechanical digester.
Article number 30 surveys several fermentation processes. Briefly described are: protein from bagasse by bacterial fermentation, production of fungal protein from cellulose, photodegradation of cellulose, fungal enzymes to produce glucose from waste cellulose, protein production using fungi fermentation, protein from alcohols, and growing yeast from solid waste.
From research, we switch to hazardous wastes in item 31. Section 212 of the Resource Recovery Act of 1970 required that EPA prepare a comprehensive report to Congress on the storage and disposal of hazardous wastes. The summary and conclusions of that report are presented in item 31, in which EPA recommends a regulatory program for their treatment and disposal. The States would implement the program subject to Federal standards in most cases.
The final selection is an article from Environmental Science & Technolooz which discusses the problems involved in disposing of sewage sludge and reviews the various methods employed.

THE QUANTITY AND COMPOSITION OF POST-CONSUMER SOLID WASTE
The Second Report to Congress (March 1974) indicated considerable improvement in our knowledge of both total quantity and composition of the nation's post-consumer solid waste stream. For the first time, estimates were presented detailing the composition of the 1971 waste stream both by material and by product type.2' -p. 3 The work done in the year since that report has not provided reasons to reject or significantly alter' the bases for the 1971 estimates. 3 4 They have been updated to 1973 and additional details developed on composition by product type, on recycling, and on projections of future trends.
Estimates for 1973
EPA's current estimates for U.S. post-consumer municipal waste for 1973, based on reported material flow statistics for 1973 and earlier years, are presented in Table 1. This table is organized in the same format as the original table for 1971 appearing in the last Report to Congress, with all figures updated to 1973 values. The same definitions and similar methods of calculation are used, so the 1973 data are directly comparable to the 1971 estimates.2 They are preliminary in the sense that they are based in part on industry statistics for 1973 that are still subject to revision by government and trade association sources. The following were the more significant changes between 1971 and 1973 (Table 2):
Total waste generation:
Total post-consumer municipal waste increased
by 10 million tons (8 percent) from 125 to 135
Per capita generation increased from 3.3 to 3.5
pounds per day (6.3-percent growth).

SOLID WASTE MANAGEMENT AND RESOURCE RECOVERY.
The Solid Waste Disposal Act of 1965 and the Resource Recovery Act, passed 5 years later, initiated the Federal Government's major efforts in the field of solid waste management.

The legislation directed EPA to carry out a number of special study and demonstration projects including methods of recovering materials and, energy from solid wastes, reduction of solid waste by requiring changes in product characteristics and packaging practices, and incentives and disincentives to recycling both in the marketplace and in public policies. Second, grants were authorized to State, interstate, municipal, and intermunicipal agencies and organizations for planning purposes. The plans could encompass surveys of disposal practices and problems, the development of regional or local recycling systems, and programs for the removal or processing of abandoned aut omobiles.
Grants to demonstrate resource recovery systems or to construct new or improved disposal facilities could be made to public agencies. As with the planning grants, cooperative efforts between two or more municipalities' entitled them to receive up to 75 percent of the costs; communities acting alone received less. Fourth, EPA was directed to publish guidelines on the collection, separation, recovery, and disposal. of solid wastes- consistent with public health and welfare and the environment. The guidelines -are mandatory on Federal agencies and on anyone receiving a permit to dispose of- solid wastes on Federal land. The Agency was also required to recommend model codes, ordinances, and statutes to States and municipalities to implement the guidelines and purposes of the act; and to issue technical and cost information on feasible processes and methods of dealing with solid wastes,
Grants for training personnel (including instructors and supervisory personnel) working in solid wastes or resource recovery were authorized; and EPA was directed to carry out an extensive study on manpower availability and requirements.
One final investigation required of EPA called for planning a national system for the storage and disposal of hazardous wastes, including radioactive, toxic chemical, and biological wastes. These materials were to be identified, current methods of disposal cataloged, and recommendations made concerning their reduction, neutralization, recovery, and dispsal. An inventory) of possible diss sitas was called for, and long- and Short-tenvi costs of developing and maintaining them were to be estimated.
Title 11 of the Resource itecare -Act created a seven-member National Commission on Materials Policy to make a 2-year study of present resources and technology, anticipated requirements of the United States and the world, ind to make recommendations on the supply, use, recovery, and disposal of materials. Economic and demographic factors were to be considered along with the natural resources, energy, and environmental components. "Materials" was defined as all "natural resources intended to be utilized by industry for the production of goods", with the exception of food. The Commission's final report and recommendations for a national materials policy appeared in 1973 and the group was subsequently disbanded.
e responsibility for implementation of the laws was vested in the Office of Solid Waste Management Programs and the Bureau of Mines. The Bureau's programs have been directed to four areas: extraction of metals, minerals, and energy from municipal refuse; improving the methods of recovery of automotive and related scrap; utilization and stabilization of mine, mill, and smelter wastes; and the recovery of materials and energy from industrial wastes.

TITLE II---SOLID WASTE DISPOSAL1
Szc. 201. This title (hereinafter referred to as "this solid wase. Act") may be cited as the "Solid Waste Disposal Act". m.poS At
FINDING AND PURPOSE
Szc. 202. (a) The Congress finds-(1) that the continuing technological progress and
improvement in methods of manufacture, packaging, and marketing of consumer products has resulted in an ever-mounting increase, and in a change in the characteristics, of the mass of material discarded
by the purchaser of such products;
(2) that the economic and population growth of
our Nation, and the improvements in the standard of living enjoyed by our population, have required increased industrial production to meet our needs, and have made necessary the demolition of old buildings, the construction of new buildings, and the provision of highways and other avenues of transportation, which, together with related industrial, commercial, and agricultural operations, have resulted in a rising tide of scrap, discarded, and waste materials;
(3) that the continuing concentration of our population in expanding metropolitan and other urban areas has presented these communities with serious financial, management, intergovernmental, and technical problems in the disposal of solid wastes resulting from the industrial, commercial, domestic, and
other activities carried on in such areas;
(4) that inefficient and improper methods of disposa of solid wastes result in scenic blights, create serious hazards to th6 public health, including pollution of air and water resources, accident hazards, and increase in rodent and insect vectors of disease,
Title I of P.L. 89-272 amended the Clean Air Act (P.L 88-906).
have an adverse effect on land values, create public nuisances, otherwise interfere with community life
(5) that the failure or inability to salvage and reuse such materials economically results in the unnecessary waste and depletion of our natural resources and
(6) iit while the collection and disposal of solid
wastes should continue to be primarily the function of State, regional, and local agencies the pro of waste disposal as set forth above have become a matter national in scope and in concern and necessitate Federal action through financial and technical assistance and leadership in the development, demonstration, and application of new and improved methods and processes to reduce the amount of waste and unsalvageable materials and to provide for proper and economical solid-waste disposal
(b)2 The purposes of this Act therefore are(1) to promote the demonstration, construction,
and application of solid waste management and resource recovery systems which preserve and enhance
the quality or air, water, and land resources;
(2) to provide technical and financial assistance to
States and local governments and interstate agencies in the planning and development of resource recovery and solid waste disposal programs;
(3) to promote a national research and develo
ment program for improved management tec9niques, more effective organizational arrangement-, and new and improved methods of collection, separation, recovery, and recycling of solid wastes, and the environmentally safe disposal of nonrecoverable
(4) to provide for the promulgation of guidelines
for solid waste collection, transport, separation, recovery, and disposal systems; and
(5) to Idefor training grants in occupations
involving the design, operation, and maintenance of
solid waste disposal systems.

SOLID WASTE MANA 6E.UENT STRATEGY
Purpose and Summary
The purpose of this document is to present an EPA solid waste program strategy for FY 1975. This document lays the ground work for guidance to EPA headquarters, EPA Regions, and to the States. It is meant to ensure that activities undertaken will conform to this strategy and are consistent with each other. As a statement of EPA's intentions, this paper is also meant to serve as a means of promoting public awareness, encouraging public participation and guiding the public on EPA solid waste management policies. The strategy should be viewed as a dynamic document, intended to be responsive to situations that develop. It will undergo revision to accommodate new needs, problems, and legislative thrusts, but the basic philosophy and framework will be continued.
This strategy is designed to encompass the activities of all agency elements involved in solid waste related activities, and most activities described will involve or require the participation of several offices within EPA. The strategy is designed to serve as a general guide for all types of wastes and residuals disposed of on land, but it is recognized that lead activity related to some residuals falls under the aegis of water or air programs or their respective research counterparts and that these wastes are covered by other agency strategies in more detail.
In summary, the major issue being addressed is one of improper waste management, resulting in problems ranging from extreme health and environmental damages to resource wastage.
The problem is caused by the fact that improper disposal is cheap compared to environmentally acceptable practices. Problems tend to result from improper actions over long periods of time, and result from practices not easily understood or visualized. Aesthetic damages are easily visualized, and represent varying impacts on human health or animal life. On the other hand, for example, groundwater contamination which is not visible can result without a proper understanding and application of the necessary environmental control procedures.
We know that leachate is formed in land disposal sites and that this liquid enters groundwater aquifers. As rain water percolates through soil, it is more or less purified depending on the constituents of the leachate and the type of soil through which it flows. In areas of high water tables and high precipitation, there is a significant potential for groundwater contamination. The extent and seriousness of this problem is now being investigated, but a current presumption of damage exists.
A number of causes for inadequate waste management have been cited (e.g., municipalities have no money, technology is inadequate, trained manpower is lacking). However, EPA believes that these problems could be overcome if a mAjor national commitment were made to control the adverse cffccts of waste management. Such a commitment would result in adequate standards and their vigorous enforcement. In turn, fiscal and other barriers would fall or be minimized.
EPA has formulated two strategic goals: to achieve acceptable and safe waste management, and to conserve natural resources. EPA is constrained in effectively formulating and implementing this strategy primarily by a lack of direct regulatory power to assure proper land disposal or groundwater quality protection. Authority to set standards on hazardous wastes has been sought from Congress.
EPA can (1) stimulate regulation by others, (2) provide limited planning support to States,
(3) carry out research, development, and demonstration, and (4) provide technical assistance.
A. Environmental Protection
The strategy to achieve environmentally acceptable, safe solid waste management relies primarily on the eventual establishment of a regulatory approach. It is the most direct attack on environmental, health, and associated problems. The approach is to direct the most dangerous types of wastes to a limited number of strictly controlled processing/disposal sites, leaving a larger number of sites to process and dispose of less hazardous wastes.
This strategy relies heavily on the States. From the State perspective, the problem is one of land disposal States generally have the power to issue regulations for all wastes and all sites and to relate the degree of control to the potential degree of hazard. Typically, however, States have issued site regulations that prohibit acceptance of hazardous wastes. The exclusion of certain wastes from disposal sites has virtually resulted in no controls for these excluded wastes. State enforcement of these regulations is severely hampered by low resources. A principal objective of the strategy is to strengthen the State role, particularly with regards to establishing authority over the disposal of all wastes. Adequate disposal site control also implies control of the movenientof at least hazardous waste from generator to disposal sites lest indiscriminate dumping take place.
The major headquarters thrust will include: developing a data base on hazardous wastes; demonstration programs to advance certain treatment and disposal methods; developing a hazardous waste regulatory strategy; augmenting knowledge on the inter-media effects of land disposal; consolidating technical/economic data on all aspects of solid waste management; and technical assistance support to improve local practices.
The approach to natural resource conservation by waste recovery and source reduction relies primarily on technical assistance. The primary barriers to waste recovery implementation are institutional constraints.
The plan is to concentrate on the evaluation and dissemination of information about existing systems to reduce perceived risk, and on working with communities seriously considering recovery options, helping them make sound decisions.
Headquarters will conduct a program of studies related to the concept of conservation through source reduction, primarily addressing benefit/cost trade-offs of economic product regulation.
Some States have emerged as strong supporters of recovery system implementation, primarily through the provision of financial assistance. Connecticut has a unique program in that it addresses institutional problems through a Waste Management Authority. The Authority puts together a package (site, system, financing backed by State bonding, contracts with firms to operate the system) for a competitive disposal fee, which covers the full cost of the system. This concept is attractive for disposal sites, as well as for resource recovery. The approach is to utilize Federal demonstration funds in one or more States to stimulate establishment of similar institutions.
C. Regional Activities
The Agency approach anticipates a strengthening of the role of EPA Regional Offices primarily to (1) provide better and more intensive relationships with States to help achieve national objectives; (2) to support enforcement efforts by States and to utilize existing enforcement powers where appropriate, and (3) to become the cutting edge of technical assistance efforts for waste management and resource recovery.
The headquarters role in support of the regions is to (1) provide policy guidance, (2) assess specific approaches taken by the Regions; (3) develop the knowledge on the state-of-theart of all types of waste management practices; and (4) provide the specialized expertise for technical assistance.

D. Basic Strategy Assumptions
The Federal solid waste management program was originally established to improve solid waste management nationally through research, development, demonstration, training, and planning activities. The major focus of the program in the 1965-1970 period was on municipal waste collection, processing, and ultimate disposal activities; and on State, local, and regional planning. In the 1970-1973 period, the focus was broadened to resource recovery, support of regulatory activities by States, and investigation of hazardous waste management problems.
It is assumed that the program will continue to evolve in a generally regulatory direction related to waste treatment and disposal activities, while in the resource recovery activities the Federal role will consist of implementation stimulation through technical assistance, information dissemination, planning activities, and demonstrations.
In FY 1975, the program is expected to operate under an extension of the Solid Waste Disposal Act, as amended. However, passage of legislation incorporating the provisions of the proposed Hazardous Waste Management Act is expected ultimately.
II. The Problem
Waste management presents a spectrum of problems, from extreme health and environmental hazard to municipal management inefficiency. The extremely diverse nature of the wastes (dead animals, mercury-rich industrial sludges, dredge spoils, abandoned cars, septic tank pumping, residential solid waste, infectious hospital wastes, demolition debris, feedlot wastes, etc.) and their manner of occurrence (in or near concentrations of population, in rural areas, etc.), means that the dimensions of waste management are very diverse. Any abstraction of the problem into categories is a dangerous oversimplification.
The problem cannot be disaggregated neatly into "hazardous" and "non-hazardous" components. Solid waste is not merely residential trash and food wastes. Such an oversimplification obscures the real situation. The early stress on municipal solid waste (by the program and by others) was because this waste is most apparent to concerned environmentalists and is easier to understand than the management of many closely related industrial, institutional, and agricultural residuals.
The basic problem is improper land disposal of wastes-all wastes-with adverse environmental consequences. Appendix B provides a more detailed discussion of this subject. A categorization, recognizing the fact that it oversimplifies the issue, follows:
Health and Environmental Effects Occur Under Five Headings
0 Health and Environmental Effeci.s Occur Under Five Headings
Water. Ground and surface waters can be polluted y land deposition of wastes. The problem ranges from contamination of waters by heavy metals and other toxic chemicals to introduction of organics and soluble gases (CO 2).
Air. Air pollution can result from incineration, open burning, or sublimation of chemicals at land sites; odors are also associated with processing and disposal facilities, especially with organic waste dumps and lagoons.
Health. Disease vectors arise from improper waste management and waste movement and disposal. The problem is associated especially with improper storage and collection of residential wastes in the inner city.
Land Use. Waste disposal alters soil biota and soil chemistry and thus affects future potential land use. For example, land contaminated by heavy metals cannot be used for food or feed crop production.
Human Safety is endangered in accidents during waste collection and at land disposal sites where hazardous wastes are handled. Migration of methane or carbon monoxide from land sites to confined areas can cause explosion or suffocation respectively.
Aesthetic and Other Problems also accompany waste management, especially the
Litter, ugly accumulations, and uncontrolled dumping; Adverse economic impact of disposal sites on land values-due to historically poor practice in management of disposal sites;
Inequitable population effects-disposal sites typically impact on a small portion of the population but serve the total population; and Inefficient management of wastes-which causes higher than required expenditures on this function by the people.
Resource Wastage. Waste management is accompanied by little or no materials or energy recovery because recovery is most often more expensive than simple dumping. This activity is wasteful so long as simple dumping is an unacceptable
practice for other reasons.
The resource aspect of waste management, however, goes beyond the fact that waste materials are not usually recovered. Waste generation is itself a symptom of national
practices that impact on the ability of the economy to supply materials and energy at requisite levels.
Ill. Nlajor Causes of the Problem
The chief environmental problems exist for a number of interrelated reasons:
Regulatory and Enforcement Gaps. Some States do not regulate disposal
effectively and most do not enforce regulations vigorously because of low
manpower resource commitments.
Resource Allocation. Municipalities do not devote required resources to
environmentally sound disposal and efficient management where such poor practice is tolerated by an apathetic population or where the impacted population
has no political power.
Aesthetic vs. Environmental Control Since litter and ugliness are typically the most obvious target of popular displeasure, municipalities may manage disposal 46 cosmetically" but not environmentally no blowing paper, no odor, but leachate
into the groundwater unless environmental regulations are enforced.
0 Barriers to Recovery. Poor disposal practice is cheaper than r--source recovery,
and the cheap option retards the consideration of recovery or other more environmentally sound practices. In this connection, however, it should be noted that recovery today is primarily a resident ial/commercial waste management
option and not a solution for all types of wastes.
Especially acute is the effect of an absence of regulate ion in the industrial, and above all the hazardous waste areas, where the cost differential between dumping and proper treatment may be twenty-fold or greater. This results in under-utilization of the private sector industrial waste detoxification, treatment, and disposal services (the existing, small industrial waste management industry operates at 25
Typically a number of other "causes" for the problem are cited e.g., municipalities have no money, disposal technology is inadequate, manpower resources are lacking or poorly trained, consultants are poorly qualified, etc. All of these are true to some extent somewhere. However, where a community makes a commitment to control the adverse effects of waste management, such problems
can be overcome.
Absence of regulatory control (envif-onmental standards, strictly enforced) is due
to some of the following factors:
9 Ignorance of the Problem. The problem has been identified recently. This is the
case with highly hazardous wastes and with the potential of groundwater contamination by leachate. General recognition of the special nature of these wastes or effluents and their adverse effect on life and the environment is a recent
Absence of Alternatives. Courts or regulatory agencies do not move against disposal site operators if there is no alternative available. Shut-down of an operation is impossible politically unless wastes can be placed somewhere else. Site operators can "blackmail" the public by threatening shut-down rather than expending resources for upgrading. This problem is closely linked with the next one, and is probably the chief obstacle to environmentally acceptable waste
management where standards exist but are not enforced.
Public Resistance to Disposal Type Land Use. Public resistance to the siting of a new disposal site is usually intense and flows from public knowledge.of poor disposal practices in the past and reduction of land values (real or presumed). This makes creation of alternatives very difficult, prevents institution of the most economical logistical systems, and thwarts enforcement of regulations where they
are in force.
Imbalance in Po;ver Between States and Large Metropolitan Areas. This
phenomenon sometimes results in enforcement of regulations in small, rural places by the State but a "hands off" policy vis-a-vis large cities that have political and
Absence of Provenl7ested Technology. This phenomenon is applicable especially for hazardous waste disposal sites. It is difficult to mandate, for instance, the disposal of pesticides in landfills without hydrological connections unless such sites exist. It is d Ifficult, to establish such sites without the necessary engineering and testing programs to identify appropriate designs and to ascertain their viability. To a lesser extent, this issue also retards recovery of some types of
resources e.g., nonferrous metals and glass.
IV. Strategic Goals
From the problem statement the following goals are formulated for solid waste management:
0 Achieve acceptable and safe waste management to protect public health and
welfare and the environment.
Conserve natural resources through institution of resource recovery or by other
means where economically feasible.
Acceptable and safe waste management (for environmental, health, and safety reasons) necessarily results in the elimination of most site-related land and groundwater pollution, litter and blight, should improve the land values around disposal sites, will minimize adverse inter-population effects, and (by imposing higher costs on disposal operators) will create incentives for fiscal efficiency and other environmentally acceptable options. Roadside litter, accumulations of abandoned automobiles or other bulky wastes, and similar littering without a health or environmental impact would not be addressed by this goal. Resource conservation would be indirectly aided by the achievement of this goal in that it would raise the costs of disposal and thus make higher cost recovery a better option.
Conservation through, recovery and other means, while indirectly supported by environmental, health, and safety related upgrading of waste management,, is singled out as a national goal because resource recovery is a new activity at this time, not yet a selfevident waste management option. Institution of recovery systems (or other measures) will require more than regulatory pressure to achieve. Achievement of the highest feasible recovery is seen as a worthwhile national goal for national efficiency, strategic, and general public welfare reasons to forestall shortages and disruptions attendant on shortages.
Both national goals are appropriate Federal or EPA goals. Environmental and health protection is the chief mission of EPA. Resource conservation is the mission of the FEA (for energy) and of Interior (for minerals). Conservation of materials and energy from ivaste can and should properly be an EPA mission in that the achievement of such recovery is inextricably intertwined with considerations of waste management and ultimate disposal and achievement of environmental and conservation objectives are mutually supportive.
V. Constraints to Strategy Formulation
A. Regulatory Power.
There is no Federal regulatory power directly applicable to all land disposal sites and land disposal practices. The Federal Water Pollution Control Act does address the issue of land application systems for the treatment of municipal wastewater. The Clean Air Act is fairly effective in addressing problems from open burning. But no effectively clear control over groundwater exists for the many other kinds of wastes and disposal practices. Control over surface water pollution from disposal sites is weak. Section 209 of the existing Solid Waste Disposal Act provides the authority to issue guidelines which are mandatory for Federal
agencies but no one else. Until regulatorN power is provided to the Agency, work will be carried out under the authority and malidates, of Section 209.
The extent of systematic knowledge (suitable for broad trade-off analysis and regulatory program justification) is relatively poor. This is especially true with regard to (1) industrial hazardous (and not-so-hazardous) waste quantities and compositions as they actually occur; current data are in the form of chemicals, not chemicals in actual waste streams;
(2) land, air, water inter-media consequences of various types of disposal, (3) the effect of hazardous and toxic materials on plant and animal life, (4) hazardous waste treatment and disposal technology, and (5) the qualities,, nature, occurrence, and handling methods related to numerous special wastes not heretofore given priority (crop wastes, animal wastes, hospital wastes, demolition debris, dredging, and a variety of nonhazardous or 44 situationally" hazardous sludges, (6) treatment and processes of the consequences of the use of the land as a disposal media, and (7) the costs and benefits of product regulation for recovery or source reduction.
State and municipal government structures, philosophies, and procedures vary greatly from region to region and within regions. Differences in geography, geology, population density, and many other factors exist. A uniform strategy for all States or all wastes or all regions is unrealistic and probably counterproductive.
V 1. Tools
Basic tools that could be used to achieve the strategic goals are listed below. Not all of these are available under existing authorities.
0 Regulatory action at various levels (Federal, State, local) including combinations
such as Federal standards, state enforcement, local implementation, etc. This includes the semi-regulatory use of guidelines and recommended procedures. Land
condemnation procedures would fall into this category.
Fiscal support such as grants, loans, subsidies, tax credits (to various levels of government and various types of organizations for a diversity of purposes) designed primarily to support capital acquisition and/or operations. This category
could include provision of land as a fiscal support mechanism.
Research, development, and demonstration, in-house or through contracts and grants, aimed at systems development and testing and environmental, health, and
0 Technical assistance, consultation, and other foems of communications to transfer
knowledge, to facilitate project or program implementation, to persuade others,
e t C.
VIL Discussion of Basic Strategic Approach
A general strategic approach to achieve the two goals formulated above is presented and discussed here. A program array for the period of this strategy assessment is presented in the next section.
A. Strategy to Achieve Environmentally Acceptable and Safe Waste Management,
and Protect Public Health
The basic elements to achieve this strategy include:
(1) Regulatory control of waste storage, treatment and disposal.
(2) Mixed Federal and State implementation based on degree of harm assoc iated with
types of wastes.
(3) Program thrust supported by fiscal support to States, R&D, demonstrations and
(4) Direct regulation and enforcement relative to Federal facilities.
Discussion. A regulatory approach is the single strategy likely to achieve a number of ends as discussed earlier. If consistently followed over a period of tim"e, it moves toward the most equitable distribution of the costs of control, provides for maximum participation by the private sector, provides incentives for efficiency and thus for cost reductions, and represents the most direct attack on environmental, health, and associated safety problems.
Significant differences in environmental and health damage are associated with types of waste, from innocuous (glass bottle) to severe (arsenic-containing pesticide). The level of attention that should be paid by the Federal government to waste management can be related to the degree of harm involved, the inter-state or national extent of damages resulting from poor management, etc. Given the ever-present resource constraints it is logical to some extent to concentrate Federal action in those areas where waste management problems have the most direct adverse impact.
General Approach. The approach is tc. direct the most severe types of wastes to a few, strictly controlled processing/disposal ;,ites, leaving the overwhelming number of other sites to process/dispose of other wastes. Thus the above strategy envisions a "cascading" regulatory strategy %vith direct Federal regulation and enforcement of very hazardous wastes, Federal standard-setting and state implementation of other hazardous wastes, and State responsibility for "'other" wastes guided by Federal guidelines.
It is stressed that a clean demarcation between "'hazardous" and "tion-hazardous" wastes does not exist except at the extremes of the spectrum. As more experience is gained the basic strategy is expected to change as well and reflect the gaining of clearer of the demarcation.
Federal Facilities. The chief exception to this general strategy is waste management on Federal facilities which is controlled under Sections 209 and 211 of the Act and Executive Order 11752. Relative to these sites, the strategy is development and direct enforcement of Section 209 guidelines (mandatory for Federal agencies) together with the necessary supporting technical assistance and administrative efforts.
State Role. This strategy relies heavily on State implementation of a Federal hazardous waste regulatory program and on a vigorous State regulation and enforcement of -other" waste management. This strategy envisions strengthening the State role through fiscal support on a flexible basis for both enforcement and for other preparation for a greater hazardous implementation role. Thus, EPA is attempting to "strengthen the State role" in all aspects of waste management.
From the State perspective, the problem is one of land disposal. States generally have authority to promulgate regulations for disposal sites and to relate the degree of regulation to the potential degree of hazard. Many States have issued regulations only for sites that receive non-hazardous wastes; a few have regulations promulgated for both. First, States that do not have the power to issue disposal regulations should acquire that capability. Second, States that have general authority should issue regulations. Third, States that have issued regulations should implement them, emphasizing the establishment of hazardous disposal sites separate from sites for other wastes where needed, available in proximity to the major waste generators. Thus, to "strengthen the State role" implies more aggressive, use of existing State permit, site approval, and enforcement powers-particularly with regards to using existing legislation to develop stricter criteria for hazardous waste disposal sites, distinct from "other" sites. Finally, States must take a more aggressive role in regulating all sites.
States can get ready for the control of hazardous waste. Current EPA. concepts rely on a waste stream-by-strearn approach to direct the worst wastes to selected sites and requires generators to show the disposition of their wastes. Few States have the authority to place
similar requirements on generators, and none have implemented authority (although the NPDES does provide some leverage). States that do not have this power should obtain authority; those with authority should implement it, As a first step, this approach implies that States should obtain knowledge of generators of wastes, a nd present management practices.
States can act to provide a facilitating role (apart from the incentives which result from appropriate enforcement) for desirable practices if the State desires-for resource recovery, hazardous waste disposal, or municipal waste disposal. Actions may include State involvement in local siting actions, use of State eminent domain powers, implementation of low cost, self-financing concept. The Connecticut Authority appears to be an attractive approach to address institutional and financial constraints in disposal, as well as in resource recovery.
To achieve the strategy, EPA will use its existing authorities to support planning and demonstration activities at the State level that (a) achieve progress toward hazardous waste control, (b) increase the pace of standard -set ti ng and enforcement relative to "other" wastes, and (c) lead to the establishment of facilitating institutions for implementation of resource recovery and hazardous waste treatment facilities.
It is recognized that the States will require some incentive for stepped-up action. Current authorities limit the range of Federal influence over State action. However,,it is assumed that a Federal standard -set t ing role will emerge from the current legislative cycle, which would require state implementation. Failing that, EPA will depend on persuasion and fiscal support for carrying out the strategy.
Hazardous Waste Technology and Effects. Because the level of knowledge is very low about control technology and effects of hazardous wastes, and because the Federal government will require hard data for standard-setting, a R&D and a demonstration element is absolutely necessary as a means of developing and justifying standards.
"Other" Wastes. In the "other" waste areas, the level of knowledge about the environmental and health effects associated with the many waste streams (animal, crop, and mining wastes; industrial slags; septic wastes; dredge spoils; various sludges and residues; and urban waste mixed or disposed of in combination with special wastes) is inadequate-particularly inter-media effects, effects on ground and surface waters, relationships between types of soils and leachate generation, etc. This strategy envisions investigations to obtain such understanding to guide better the assessment of Federal strategies in the future.
B. Strategy to Conserve Natural Resources by Waste Recovery and Source
The basic elements to achieve this strategy include:
(1) Technical assistance to promote implementation of energy and materials recovery
(2) One-time state recovery program support.
(3) Limited demonstration of technology to enlarge the technical options.
(4) Investigation of cost/benefit aspects of product regulation and other source
Discussion. The fundamental barriers to implementation of waste recovery are (1) institutional constraints arising from the need to form novel institutional arrangements to practice recovery and (2) the high risk associated with full scale demonstration of new technology, which prevents demonstration of such technology with private or State/local funds.
EPA analyses indicate that resource recovery is already economically feasible in many areas, will become more so as regulatory thrusts are initiated, and is not impeded by fiscal constraints (State, private, and municipal funds' are available).
The ability of the consulting community to provide technical aid and consultation is severely limited largely by the fact that new systems are proprietary and the basic information is Federally held (in demonstrations). Thus this strategy envisions a two-fold thrust to provide technical assistance to communities and States and to improve the ability of the consulting community to provide services.
Some States have emerged as strong supporters of recovery system implementation: Connecticut, for instance, with Federal support, established a state-wide plan, an independent authority with funding powers ($250 million in bonding authority), and a strong state regulatory program (to foreclose cheap options). The state-wide scale provided by such programs, the State financing potentially available after an initial planning/implementation effort, and the ability to establish large and intelligently located facilities (that provide needed specialized as well as general purpose facilities) indicates that the State role in recovery can be strengthened by intelligent use of Federal resources.
Measures to reduce the generation of waste in essence represent changes in products and distribution systems undertaken either voluntarily or by legislative fiat. Such interventions,
unless minor, tend to be associated with costs to the economy in terms of disruption (jobs lost, equipment obsoleted, locational shifts, etc.) and must be carefully weighed against benefits. The benefits are reduced pollution, conservation of rawv materials, and avoidance or minimization of the disposal function. Because the benefits of reduced consumption (achieved through less materials-intensive or longer-lived products or through substitution of reusable for one-time-use products) are very significant, assessment of such conservation options is a key part of the EPA strategy. However, because of the great variety of products that must be examined, the approach will be selective, targeted to products or product categories that promise the most success of achievement at lowest cost.

II. OSWMP FY 75 PROGRAM PERSPECTIVE
The Office of Solid Waste Management Programs is a small program in the Environmental Protection Agency. It consists of a staff of 125 and in Fiscal Year 1975 had a base budget of about $12.3 million. Additional funding received subsequent to approval of the base budget raised the total amount of dollars managed by OSWMP.in 1975 to approximately $20 million, Other portions of the Agency, the office of Research and Development and the 10 EPA Regional offices also are involved in solid waste management.
The OSWMP is not a regulatory program. The existing Solid Waste
Disposal Act, as amended, was extended in FY 75. Several hearings were held on substantive amendments to the present Act but new legislation did not pass either the House or the Senate.
A major accomplishment in Fiscal Year 1975 was the publication of
an Agency solid waste management strategy in October 1974. This strategy statement gives the priorities for the Agency's solid waste management efforts, and details the programmatic thrusts of the program. The Agency goals as stated in the solid waste management strategy are to achieve acceptable and safe waste management, and to conserve natural resources.
To meet these goals the Office is attempting to develop a better
understanding of the environmental problems caused by improper management of certain wastes that may be "potentially hazardous." Our Hazardous Waste Management Division (HWND) focused on this effort. HWMD is establishing a data base to understand the sources of wastes (mostly industrial sources), the potential environmental damages that are or may be caused by improper management of those wastes, and the technology options that may be applied or be needed to reduce or eliminate potential damages. Major studies are underway in 13 industry groupings in the U.S. to define quantitatively and qualitatively thir hazardous waste streams. A large study is underway to test the acceptability of various thermal reduction processes to destroy certain hazardous wastes and a major project to demonstrate the land disposal of chemical (hazardous) wastes was initiated in FY 75. This Division is also developing the necessary tools and capabilities necessary to enable hazardous wastes to be regulated to protect environmental quality and public health. Studies are underway to interpret and understand other environmental regulatory programs and to develop recommended procedures for hazardous waste management. This Division has been delegated the responsibility to issue disposal regulations for pesticides and pesticide wastes under the FIFRA, as amended. This Division also works with the States and others who are developing their own regulatory programs directed toward potentially hazardous" wastes. Major program elements of HWMD are guidelines development, data base development, and program implementation. Major projects in the HWMD are described under these headings in Section III of this report.
A major focus of the Systems Management Division (SMD) is the
development of a better understanding of land disposal practices for wastes. In the past, OSWMP focused primarily on land disposal for municipal solid wastes, but during FY 75 increased resources were devoted to understanding the effects and practices of disposal and/or utilization of municipal sewage sludge on the land. SMD, is supporting the Water Supply Office of EPA by preparing a Report to Congress, as required by the Safe Drinking Water Act, on the impacts of all land disposal practices on groundwater. Our land disposal efforts are to characterize the nature of leachate generated and potential or actual groundwater contamination from a variety of land disposal practices, to understand the technology of leachate collection and treatment, and to work with communities to better implement sound waste disposal practices. SMD has initiated a project to demonstrate anaerobic treatment of leachate and has underway a project to determine the acceptability of utilizing municipal sewage sludge as a soil conditioner and supplement in growing turf. This Division also addresses conventional solid waste management; with significant efforts directed toward the promotion of collection efficiency and safety in solid waste management. Of particular interest is the technical assistance capability and supportive tools of SMD which when utilized by cities and industries can significantly reduce their collection costs. SMD is also developing guidelines for the collection of municipal, commercial and institutional solid wastes under Section 209 of the Solid Waste Disposal Act, as amended. Major program elements of SMD are technical assistance, land disposal and special wastes. Major projects in the SMD are described under these headings in Section III of this report.
A major focus of the Resource Recovery Division (RRD) is the
implementation of systems to recover energy and materials from solid waste. RRD currently manages 5 large resource recovery demonstration projects, (two in materials recovery and 3 in energy recovery) and is attempting to stimulate the adoption of systems to separate wastes at their generation source for separate collection and recovery. RRD devotes considerable effort in studies and analyses to determine what actions are needed to stimulate increased demands for secondary materials and increase the practice of waste redUction. RRD also is responsible for the preparation of the annual Report to Congress on Resource Recovery and Waste Reduction as mandated by Section 205 of the Solid Waste Disposal Act, as amended. This Division is also responsible for developing
4 guidelines for resource recovery under Section 209 of the Solid Waste Disposal Act, as amended, These guidelines address the sale of returnable beverage containers at Federal facilities, source separation and separate collection of wastes for recycling; implementation of large scale resource recovery facilities to recover materials and energy; and Federal procurement of products containing material recovered from post consumer wastes. major program elements of RRD are materials recovery# energy recovery, and waste reduction. Major projects in the RRD are described under these headings in Section III of.this report.
During FY 75 $3.0 million was allocated to the Agency's Regional offices to fund planning, d nstration and training projects of State solid waste management programs. The Regional Administrators were allowed maximum flexibility in awarding grants to State programs in order to implement the State role as envisioned in the Agency's Solid Waste Manag nt Strategy for PY 75.
Grant funds were utilized by the State solid waste management
program to increase efforts in the enforcement of State regulations for solid waste processing and disposal facilities, to initiate State-wide hazardous waste surveys,, and to conduct the planning necessary to encourage material and energy recovery from solid waste.

STATEMENT OF D-& THOMAS V. FALRIE, DIrECTo. BREU or MINES,
DKPARTME.1T OF THE I.1TRIOE
Mr. Chairman and Members of the Committee. thank you for asking me to participate in these hearings and to discuss with you our views on solid waste management. We have always supported the twin objectives of increased recycling o wastes and improved waste disposal practices. In our view, secondary resure recovery is not only desirable as a means of augmenting our primary supplies of raw materials, but is also essential from an environmental standpoint to reduce the ever-increasing volumes of wastes that must be disposed of. Since its creation by the Congress in 1910, the Bureau of Mines has been concerned with recycling mineral-processing wastes and with the refining of secondar metals such as lead, zinc. copper, and brass. In recent years, we have focused attention on recovering metals and minerals from urban refuse and a variet-y of industrial wastes, and on devising methods for more effectively processing junk autos to encourage more complete recycling of the metals and nonmeral ic constituents. I would like to describe what is being done and what can be done to assure more effective reuse of these wastes.

Urban refuse is a rich potential source of recyclable minerals and metals. According to the Environmental Protection Agency, about 125 million tons of refuse-cmprising household, commercial, and some industrial wastes-are collected and disposed of yearly by our cities and municipalities (table 1). These wastes contain 9 million tons of iron and steel, more than 1 million tons of nonferro is metals, about 12 million tons of glass, and over 90 million tons of combustibles. The heating value of the coml)ustil)les is equivalent to about 45 million tons of coal. or inore than 200 million barrels of oil per year, which could reduce our dependency on interruptible and high cost fuels from abroad. The estimated griss value of the recoverable materials in the refuse is $1.4 billion.
Two processes have been developed in our laboratories for recovering the valuable materials from the refuse. One process is applicable to incinerated refuse and the other to treatment of the raw refuse. Both processes employ simple techniques and equipment that have been used in the minerals processing industry for many years in recovering metals and minerals from their ores. Bureau of Mines metallurgists have taken these techniques and equipment and adapted them for the job of waste prevention.

Of the refuse generated, about 30 million tons are currently burned in some 200 municipal incinerators operating through the United States. Incineration is expensive, but it serves to reduce the volume of the refuse by some 90 percent. Thus substantially less land space is required for disposal of incinerated refuse (incinerator residues), than for raw refuse. The incinerator residue is like a mineral ore, containing iron, glass, and nonferrous metals such as aluminum, copper, lead, and zinc (figure 1). These components are readily separated by a series of screening, grinding, jigging, and magnetic separaeon steps, as shown in figure 2. The process has been developed in a pilot plant, capable of treating about 12 tons of residue daily, which the Bureau has been operating at its Metallurgy Research Center just outside of Washington, at College Park, Maryland (figure 3). This process will be demonstrated in a plant having a daily capacity of 1250 tons of residue. The plant is being constructed by the city of Lowell, Massachusetts, on a cost-sharing basis with funds provided by the Environmental Protection Agency, and will treat the residues from several incinerators in the Lowell area. On the basis of extensive tests in our pilot plant, we estimate that recovery of the metals and glass from incinerator residue can provide a net credit, exclusive of marketing, transportation, and other indirect costs, of almost $15.84 per ton of incinerator residue processed (table 2).'

FIGURE 5.-Partial view of iaw refuse separation pilot plant.
Nationwide, most refuse-amiounting to about 95 million tons per year-is not incinerated but disposed of in landfills. Treatment of this raw or unburned refuse with techniques developed by the Bureau of Mines yields a combustible fraction as well as metal and glass products (figure 4). This process is being demonstrated in a pilot plant having a capacity of 5 tons per hour which is operating at our College Park Metallurgy Research Center. Figure 5 shows a view of the plant, and typical feed material appears in figure 6.
Our tests indicate that operating costs for a plant processing 1,000 tons of refuse daily would be about $2.70 per ton (table 3). The estimated gross value of the product obtained in such an operation would be $10.91 per ton, netting a gain of $8.21 per ton of refuse. In addition, $3.00 per tonl in landfill costs would be saved. The processing system (figure 7) has attracted national and international attention, and adaptations of the process have been announced by several local governments, such as Mlonroe County (Rochester), New York, and Baltimore County, Maryland, as well as the governments of France and Spain. The Bureau offers technical assistance to all parties interested in applying all or part of the system, to the solution of their solid waste management problems.
Technology developed by the Bureau of Mines and others has stimulated widespread activity to implement solid waste management through recycling.

Figure 8 indicates the extent of demonstration projects and commercial installation.-s planned, under construction, or operating on the State and local levels. The techniques being adopted include a variety of pyrolysis. fuel substitution, and materials recovery processes. Much-Iprogress has been made and we are sure that continued effort will lead to further advances in the future as the country progresses toward extensive )ractice of solid waste recycling.
Concurrent with work on urban refuse, we have been developing new and
better methods for processing junked motor vehicles at our Salt Lake City (Utah) 'Metallurgy Research Center. About 9 million cars, trucks, and buses arejunked annually here in the United States (table 4). Approximately 8 million of these vehicles are scrapped to recover the iron and steel: 4 million by shredding and 4 million by hand dismantling. However, a large proportion of the nonferrous metals and nonmetallic materials simply goes to waste. In addition. about 1 raillion junked vehicles per year are not recycled and instead enter an idle "inventory" estimated at between 12 and 20 million units.
One of the immediate problems faced by small-scale processors of junk cars several years ago was the promulgation of air quality regulations which prohibited the open burning of cars. B(ause burning is a vital step in the preparation of jnk cars for hand dismantling and shearing or bundling, the Bureau developed an improved smokeless incinerator for automobiles which junk car lpr(cessors can construct at minimal cost (figure 9). Currently there are more than 30 incinerators of this design operating in the United States.
Large-scale processors mechanically shred junk cars at a rate of 25,000 to 300,000 units per year to produce fist-sized chunks of metal.

Substantial progress has been made in treating some of them. For examl)le, in primary alumninum smelting operations, about 200 lbs of dross are produced for each ton of metal I)rocessed. This dross contains a significant quantity of metallic aluminum that must be recovered to maintain the effliciency of the overall smelting process. In current industrial practice, recovering the aluminum produces a high-salt slag that is difficult to dispose of because of the possibility of water pollution. AInd it still conltalins some Iinely-(livide1 aluminum that should be recovered. In cooperation with firms that process dross, we are working to improve the efficiency of aluminum recovery and to avoid the rLsk of water pollution. We are also looking into the practicability of alternative procedures that would bypass the high-salt slag altogether.

Water pollution-alnd the loss of valuable materials-affects many other in*dustrial operations. For instance, waste solutions from electroplating operations are a problem in virtually every in(dustrialized area of the country. If disposed of without treatment, they pollute the water and often release toxic constituents. They also carry valuable metals out of the recycling circuit. We solved part of the problem by the simple step of bringing together, in physical combination, waste solutions from different, adjacent operations. By combining acid waste and cyanide solutions, metal cyanide compounds are precipl)itated, the acid is neutralized, and water acceptable for reuse or discharge to streams is produced. The metals can then be recovered from the solid precipitate that is produced. We call this the wvaste-plus-waste technique, and it works.
Lead storage batteries are as ubiquitous as our automobiles. When the batteries are worn out, the lead in them is recovered for reuse. Table 6 shows how much lead and antimony (alloyed with the lead to make it stronger )is recovered. Current practice uses Ilast-furnace smelting of lead-battery scrap to produce secondary lead, but this opeIration also generates sulfur dioxide. To avoid the productionmi of this pollutant the Bureau of Mines developed a technique to tie up the sulfur with lime as calcium sulfate, before smelting. One West Coast processor addel the step to his operations almost as soon as we announced its development.
Sulfur dioxide in industrial stack gases cannot always be handled by a simple preliminary treatment of the material being processed or burned. To meet air pollution requirements, this sulfur dioxide must be removed from stack and flue gases. And in major operations like copper smelting and electric power generation, the sulfur in the gas waste represents a significant resource loss if it is not recovered in a reusable form. The most prominent method now receiving attention for desulfurizing these gases is limestone scrubbing, which produces enormous quantities of waste calcium sulfate sludge, and does not recover the sulfur for use. We feel that the Citrate Process developed by the Bureau of .Mines offers a better alternative for gas cleaning bec-ause it recovers elemental sulfur, an easily used material.

FiouRE 12.-Generalized citrate process flowsheet.
Figure 12 shows the essential steps of this process. After sulfur dioxide is scrubbed from the gas stream by the citrate solution, it is reacted with hydrogen sulfide to produce sulfur and release the citrate solution for reuse. The process was originally developed to clean up smelter smoke. Now we are moving ahead with a major pilot plant to apply the Citrate Process to powerplant flue gas. For a typical powerplant burning 3-percent sulfur coal, we estimate that the citrate scruIbbing step will add about 2 mills to the cost of a kilowatt-hour of-electricity.
The progress in solid waste imanagenient to date., and the rate which new technology is being accepted and utilized, clearly indicate that our Nation is headed in the right direction. Therefore, we believe that the technologic approach should be continued. Many unsolved waste problems still require technical solutions, and much of the technology currently being developed will require large-scale demonstration as part of the technology transfer process. H.R. 406 and H.R. 5487, however, would divert our country's attention from this urgently needed effort and channel national efforts instead into an extensive regulatory program. Rules and regulations, we believe, are best decided as local issues, and waste management laws, in our views, should be left in the hands of State, County and local governmients. The most effective Federal role in solid wastes is one of technical assistance and research and development. With regard to H.R. 406, we agree that the legislation could help reduce the amount of metal and glass being discarded. However, the effect of banning noureturnable containers would be minimal in terms of our overall solid waste burden in that many other items besides beverage containers are disposed of in solid wastes. In addition, it could result in other adverse consequences, not all of which are entirely clear. Furthermore, enactment of H.R. 406 might lull citizens into a mistaken belief that the country's solid waste management needs have all been taken care of. With respect to H.R. 5487, we believe existing authorities are adequate to meet existing needs and to carry out an appropriate Federal program. In any event, consideration of an expanded program such as this measure contemplates should be deferred in view of the economic and budgetary considerations outlined by the President in recent months.
