Refuse-Derived Fuel. Many processing faciUties divert a portion of the material that is not recovered for recycling to waste-to-energy plants, also referred to as resource recovery faciUties, where the material is employed as fuel. The processes involved in the production of refuse-derived fuel (RDF) are outlined in Figure 4 (23). Nine different RDFs have been defined, as Hsted in Table 3 (24). There are several ways to prepare RDF-3, which is perhaps the most popular form and is the feed used in the preparation of densified refuse-derived fuel (d-RDF). AH forms of RDF are part of the broader set of waste-derived fuels (WDF), which includes various waste biomass, eg, from silvaculture or agriculture (see Fuels frombiomass Fuels fromwaste). 

Resource Recovery Act, 1970 The Solid Waste Disposal Act of 1965 was amended by Public Law 95-512, the Resources Recovery Ac4 of 1970. This act directed that the emphasis of the national solid-waste-management program should be shitted from disposal as its pri-maiy objective to that of recycling and reuse of recoverable materials in sohd wastes or the conversion of wastes to energy. 

RCRA formed teclmical assistance panels and called for tlie research, development, demonstration, and evaluation of teclmologies for recycling and resource recovery. CERCLA was the begimiing of the remediation of Imztirdous waste sites.

Photocopies of journal articles relating to the Unipet process for the recycling of PETP developed by United Resource Recovery Corp. Details are given of the process which enables contaminated PETP to be recycled by the use of caustic soda which reacts with the PETP to yield ethylene glycol and terephthalic acid, followed by heating and evaporation of the EG which reduces organic impurities to carbon dioxide and water and leaves solid terephthalic salt. Its implications for the industry are also discussed. 

Materials recycling or resource recycling is essentially resource recovery, which is the means by which waste resources usually destined for disposal are used as secondary resources or secondary raw materials to serve as valued inputs to the economy, fulfilling both producer and consumer needs. Resource recycling, as has been pointed out, increases the supply of available material, and thereby offers a potentially attractive means of reducing...

Combustible portions of the wastes that cannot be recycled are then burned to produce energy. In this respect, a resource recovery plant is similar to a waste-to-energy incinerator. In fact, the terms resource recovery plant and waste-to-energy incinerator are sometimes used interchangeably. Noncombustible materials in waste are then shredded and buried in a sanitary landfill. Since they are treated before dumping, they tend to take up less space and are more suitable for landfill disposal. 

Recycling programs have been remarkably successful in the United States since the 1960s. In 2000, there were curbside "source separation" recycling programs in 9,250 communities. In addition, there were 3,800 separate programs for the collection of yard trimmings. As already noted, resource recovery plants had become somewhat less popular, with just over 100 such plants in operation in 2000. These plants had a total daily capacity of 95,700 short tons (87,000 metric tons) of wastes. 

Recycling and resource recovery includes technologies that either directly use waste from one process as raw material for another process or recover valuable materials from a waste stream before the waste is disposed of. Some of the spent chemical process baths and much of the rinsewater can be reused for other plant processes. Also, process chemicals can be recovered from rinsewaters and sold or returned to the process baths. This section describes some of the recycling and resource recovery technologies available to the metal finishing industry. 

Since 1976, the California Waste Exchange has successfully recycled numerous waste streams. In one year over SO waste streams were recycled that had previously been disposed. The Resource Recovery Unit is convinced that by keeping industry well informed the old "throw away ethic" can be changed to a more conservationist mode of thinking.

The checklist is divided into three areas 1) Material Storage and Handling, 2) Production Processes and 3) Treatment Alternatives. Material degradation, samples, spills, storage, and inspections are addressed in the first section. Production processes include source reduction for process bath solutions and rinse systems, resource recovery and recycling, and solvent management. Treatment Alternatives focuses on process water pretreatment, modification of conventional wastewater treatment, and alternative waste treatment methods. Each of these subsections follow the question and answer format. 

This factor is used to categorize the option within the waste reduction hierarchal structure. The preferred hierarchy is source reduction, resource recovery and recycling, and alternative treatment (The fact sheet on waste reduction for metal finishers can help identify an option s place within the hierarchy.) Each category or level has a point value assigned to it. The six levels are ... 

This technology meets the goal of waste Minimization and Resource Recovery as defined in RCRA. The process produces products and is considered recycle technology. Elimination of "cradle-to-grave" liability is possible with this technology.
