摘要: The present invention addresses the processing of waste and low-value products to produce useful materials in reliable purities compositions, at acceptable cost, without producing malodorous emissions, with high energy efficiency. In particular, comprises a multi-stage process that converts various feedstocks such as offal, animal manures, municipal sewage sludge, tires, plastics, otherwise have little commercial value, including gas, oil, specialty chemicals, carbon solids. subjects feedstock heat pressure, separates out components, then further applies pressure one or more those components. Various produced different points may be recycled used play other roles within process. an apparatus for performing converting into materials, least oil product arises from
