Processing methods Noncombustible materials such as Glass and Metals are removed during the post treatment processing cycle with an Air Knife or other mechanical separation processing. The residual material can be sold in its processed form (depending on the process treatment) or may be compressed into pellets, bricks, or logs and used for other purposes either stand alone or in a Recursive Recycling process. Williams, P. (1998) Waste Treatment and Disposal. John Wiley and Sons, Chichester Advanced processing RDF methods (pressurised steam treatment in an autoclave) can remove or significantly reduce harmful Pollutants and heavy metals for use as a material for a variety of Manufacturing and related uses. RDF is extracted from MSW using Mechanical Heat Treatment , Mechanical Biological Treatment or Waste Autoclave s. The production of RDF may involve some but not all of the following steps:
END MARKETS RDF can be used in a variety of ways to produce electricity. It can be used alongside traditional sources of fuel in coal power plants. RDF can be used in the cement kiln industry, where the strict standards of the Waste Incineration Directive are met. RDF can also be fed into Plasma Arc Gasification modules, Pyrolysis plants and where the RDF is capable of being combusted cleanly or in compliance with the Kyoto Protocol , RDF can provide a funding source where unused carbon credits are sold on the open market via a carbon exchange. However the use of Municipal Waste contracts and the bankability of these solutions is still a relatively new concept thus RDF's financial advantage may be debatable. REGIONAL USE Iowa The first full-scale Waste-to-energy facility in the US was the Arnold O. Chantland Resource Recovery Plant, built in 1975 located in Ames, Iowa. This plant also produces RDF that is sent to local power plants for fuel. Arnold O.
