102 Comprehensive Review of Solid Waste Collection and Disposal Options. including MSW. Plasma arcs were commercialized in the metallurgical industry where the high temperatures produced in the reactor vessel (potentially up to 10,000 °C) are used to create special alloys. Some of the electric power generated by the plant is siphoned off to power the torches. The basic plasma are process is shown in Exhibit 12 -7. Exhibit 12 -7.

In an autoclave process for solid waste, mixed MSW is fed into a reactor vessel where it is subjected to heat, pressure and agitation. The reactor conditions cause the organic fraction of the waste (i.e., food scraps, fiber /paper products and vegetation) to break down into a pulp -like substance that potentially has reuse applications depending on the degree of post- processing selected. The pulp has been demonstrated with a few systems to be a useful soil conditioner and also is being tested for use as feedstock for the production of ethanol, an alternative vehicle fuel and in the production of a RDP for combustion in power plants. The process also claims to provide a higher quality recyclable product. PIastic recyclable materials are softened and occupy less volume downstream. Product labels on glass, plastics and metals are totally removed and these materials also arc cleaned and sterilized. A basic autoclave process is shown in Exhibit 12 -8. v2.1 168 10/22/12
