Abstract
A method for composting solid waste material wherein, in initial treatment stages an optimum particle size is developed at a comminution station. Following an initial air classification arrangement, heavy inorganic materials are segregated to the extent that aluminum, glass and paper characterized products are removed for recycling purposes. A characterizing feature of the invention resides in the development of an optimized moisture content or digestible classified size optimized material at a relatively early stage prior to maceration developing a pulpous substance for digestion. A pug-mill arrangement is utilized for adding optimized moisture prior to digestion and maceration and a cage mill is utilized for the maceration stage of the process.
