摘要： Municipal refuse including glass articles, metal cans, paper, plastics and wood, is dumped onto a conveyor and has magnetic materials removed therefrom and the remaining refuse conveyed to a hammermill which reduces the refuse into small particles which are conveyed by positive air pressure to the upper cyclonic separator chamber of a tank the lower chamber of which contains liquid on the surface of which the light weight floatable particles collect and the heavy solid particles such as glass and non-ferrous metals sink to the bottom of the tank, the slurry mixed with sewage sludge and reduced in a wet pulping apparatus into a homogenized mix which is compressed in a screw type dewatering device wherein about fifty percent of the moisture content is removed, providing material free of glass and of all types of metals, ready for composting, for example, in windrows on the ground in the out-door atmosphere.
