ABSTRACT:
Dumped solid waste is mixed with sand and fed through a shredder. Sorters sort aluminum glass and ferrous materials from the shredded waste, and an indirect fired dryer heats the remaining shredded waste. Dust in gases from the dryer is removed in a bag house. Sand is added to the dried, shredded waste, and the waste is cooled and stored in surge storage. The shredded, dried, cooled and stored waste is fed to one or more reducing chamber units. Waste is moved through individual chambers within the units with augers and is gravitationally fed between the chambers. Gases from the chambers are condensed, and the condensate is stored as oils. Solid products from the reducing chamber units are cooled. The sand is separated from the solid product. The resultant solid product and oils may be sold as fuel and feedstock, or the resultant product may be pulverized and combined with the oil in a slurry which is used as a fuel or a feedstock.
