Abstract

There is provided a system for segregating through comminution and classification solid waste into ferrous metal, inorganic, and organic fractions. The inorganic fraction is further classified into aluminum and glass fractions. The organic fraction is further comminuted, dried and fed to a pyrolysis system where it is converted to gas for use in drying the organic material for feed to the pyrolysis system, pyrolytic oils and char. The principal saleable products recovered are char, pyrolytic oils, glass, aluminum, and ferrous metal.
