ABSTRACT:
An apparatus for processing waste material comprises a piston arrangement acting upon a mass of refuse in a receptacle formed by a cylindrical wall and a counter-piston constituting the bottom. The counter-piston can rise in such a way as to block sludge outlets in the cylindrical wall during the initial phase of compression of the waste by the piston arrangement. Thereafter, the counter-piston descends so as to free the sludge outlets when a certain pressure is attained. The compression-piston arrangement comprises two coaxial pistons designed to ensure constant, substantially uniform pressure in the mass of waste. Thus, virtually all liquid, semisolid, or viscous materials can be extracted from the waste to obtain sludge useful in agriculture. Also obtained are virtually dry and non-brittle blocks of refuse which has not been crushed but subjected to internal shearing and contraction, thus yielding a good agglomerate. These blocks may be used as fuel briquettes.
