ABSTRACT:
Process for the production of pressed bodies from municipal refuse or waste, especially refuse having a content of wood-based materials, plaster and animal and vegetable substances, in which the refuse is subjected to a treatment for reducing particle size as well as for the separation of metals and similar hard, inorganic fractions. After collection, the refuse is divided up without the addition of fluid and is thereafter dried in a hot gas to reduce the water content. The particles of refuse material are screened in an air stream to separate heavy fractions and thereafter are pressed to pressed bodies during the addition of an adhesive and/or binding agent.
