ABSTRACT:
A compression and volume reduction treatment apparatus for solid waste including a compression sleeve for receiving therein a cylindrical vessel filled with the solid waste and a press ram arranged above said compression sleeve movable upward and downward for compressing, at high pressure, the cylindrical vessel in the compression sleeve. The compression sleeve includes an upper straight large diameter portion, a lower straight small diameter portion and an intermediate tapered portion, thereby compressing the cylindrical vessel and reducing its volume in three dimensional directions by compressing the vessel radially inwardly at the tapered inner surface of the intermediate tapered portion and compressing axially at the inner surface of the lower straight small diameter portion when the cylindrical vessel in said upper straight large diameter portion is urged by said press ram in a uniaxial direction.
