Abstract
In a process for working up house refuse for moulding purposes the refuse is freed from metal bodies, pulverised, sterilized to destroy germs injurious to health by boiling with water and lime, and mixed with one or more of the subsubstances specified below for rendering the animal and vegetable constituents organically inert; the resulting mass is then moulded, the bulk of the liquid being removed from the mass before or during moulding and the moulded articles dried. The substances used for rendering the p animal and vegetable constituents organically inert are mercury, copper or other heavy metal salts, formalin, organic acids, or inorganic acids such as sulphuric, nitric or phosphoric acids. After the animal and vegetable constituents have been rendered organically inert the mass may be treated with substances which wholly or partly break down or disintegrate the fibrous substances contained in the refuse e.g., the mass may be treated with boiling soda lye or sulphite lye and the mixture then acidified to reprecipitate the dissolved cellulose substances. About 3 per cent of aluminium sulphate may be added during the stage of rendering the animal and vegetable constituents organically inert in order to obtain a greater firmness and resistance to the action of water in the final product. The refuse used may be wholly or partly freed from ash constituents. The mass may be moulded into wall-boards, slabs, ceiling and other building materials.
