Abstract

The invention relates to apparatus and a method for the processing of waste material. The apparatus includes a shaft (14) which passes along a chamber (12). The chamber has flights (22) formed therealong and which act to move waste material along the chamber. The shaft is formed of two portions, a first portion (36) which is rotatable in first and second directions, and a second portion (38) connected to the first via a clutch assembly (34) which is rotatable in only one of said first or second directions. The provision of the apparatus allows the processing and disposal of waste material in liquid and liquid/ solid solution from one discharge outlet (8) and the discarding of the remaining waste material in an other form from a second discharge outlet (18) using the same item of apparatus.
