Compact Waste Facility

Transfer and Transport of Hazardous Wastes The facilities of a hazardous-waste transfer station are quite different from those of an industrial or municipal sohd-waste transfer station. Typically, hazardous wastes are not compacted (mechanical volume reduction). 

The third example is compact cleanup units for waste treatment, mainly in consideration of the numerous radioactive sites, stemming from cold-war military developments [106]. The Hanford, Washington, USA, site with a multitude of seriously contaminated tank wastes is among them. Due to the unknown character of most polluting species, the installation of a central waste-treatment facility is said to be not the best and most inexpensive solution. Rather, small modular units, able to be individually adapted to various separation tasks, which are inserted into the tanks and perform cleanup on site, are seen as the proper solution. 

In engineering terms, a sanitary landfill is also sometimes identified as a bioreactor due to the presence of anaerobic activities in the wastes. As such, landfilling sites need the incoming waste stream top be monitored, as well as placement and compaction of the waste, and installation of landfill environmental monitoring and control facilities. Gas vent and leachate collection pipes are important features of a modem landfill. 

Low-Level Waste Low-level waste (LLW) consists of contaminated dry trash, paper, plastics, protective clothing, organic liquids such as liquid scintillation samples, and the like. LLW is produced by any facility that handles radioactive materials such as nuclear power plants, medical facilities, colleges, and so forth. In the United States, commercial LLW is sent to one of three disposal sites (Barnwell, South Carolina, Richland, Washington, and Clive, Utah). Due to the limited size of these sites (and similar disposal sites through the world) and steeply escalating costs for waste disposal, the primary goal of LLW treatment prior to disposal is volume reduction, either by incineration or compaction, followed... 

In 1992, NRC and EPAissued the National Profile on commercially generated mixed low-level waste (Klein et al., 1992) in response to a request from the Host State Technical Coordinating Committee (Alvarado, 1990). In its request, the committee stated that the information was needed by states, compact officials, private developers, and federal agencies to plan and develop treatment and disposal facilities for commercial mixed low-level waste. The National Profile was based on a survey of over 1,300 licensed nuclear facilities. 

Another piece of legislation, The Low-Level Radioactive Waste Policy Act of 1980, establishes the policy that each state is responsible for disposal of the commercial low-level waste generated within its borders and that such waste can be most safely and efficiently managed on a regional basis. The law encourages states to enter into interstate compacts to establish and operate regional disposal facilities for low-level waste. This law requires subsequent approval of the compacts by the Congress. 

One of the biggest concerns people have is that the bottles and cans they throw away today will either accumulate in unsightly, unsanitary landfills or go up in smoke from an incinerator. But the fact of the matter is that new waste treatment facilities in nearby counties soon will eliminate most of the need for landfills and incinerators. By compacting unsorted trash into blocks comparable in hardness to concrete, the new facilities make it available for use in building foundations, dikes, and road construction. This form of recycling — not part of the present proposal — doesn t require us to collect the garbage in any new way because it doesn t matter whether the content is coffee grounds or juice bottles. 

Some dry solid wastes can be compacted to reduce their volume. Some generators have developed centralized local facilities to do this, while others place these materials into separate containers for the waste disposal firm to carry out this waste volume reduction technique. 

After initial efforts to develop regional disposal facilities revealed the need for additional legislative specification. Congress passed the Low-Level Radioactive Waste Policy Amendments Act (the Amendments Act) that authorized a compact with an operating site to disallow the importation of LLRW generated in states outside the compact beginning in 1993 (Public Law 99-240). 

Waste produced during the operation of a nuclear cogeneration plant, liquid, solid and gaseous, both radioactive and non-radioactive, is subject to processing in a way similar to that applied in present-day LWRs. Liquid radioactive waste is processed by specialized water treatment facilities with subsequent solidification and compaction. Solid radioactive waste is treated and compacted. The processed waste in containers is removed to centralized storage gaseous radioactive waste is trapped by filters. 

Compared to a conventional aqueous process, the pyro-process has fewer process steps, and the facility and equipment are much more compact, which contributes to the reduction of waste. 

All wastes have been stored in waste storage facility in JAERFs site. However, it must be necessary to consider minimizing the volume of the radioactive waste by various methods such as melting and super compaction. 

The base liner in modem waste containment facilities is typically a double-composite liner system. Double-composite liner systems are used to contain municipal solid waste and are required for waste containment facilities designed to contain hazardous waste. The primary liner system of a double-composite liner system typically includes a geomembrane and a geocomposite clay liner as the primary barrier layer and a geomembrane underlain by a compacted clay liner composite as the secondary barrier layer.
