Abstract:
1. A method for the continuous drying of waste organic material to produce a combustible fuel product comprising the steps of: (i) in a first stage of the method, carrying out aerobic decomposition of pre-blended portions of the organic material deposited sequentially into a heating zone of a chamber; (ii) withdrawing hot exhaust gases generated by the aerobic decomposition of the waste organic material from the heating zone thereby effecting an air-to-air heat exchange with clean ambient intake air to produce a stream of heated air for drying; and (iii) in a second stage of the method, sequentially moving portions of the waste organic material from the heating zone to at least one drying zone of the chamber and, distributing hot air from said stream through the material to bring it to a state of dryness having a moisture content of about 20% for use as a fuel.
