ABSTRACT:
A method of treating and using waste products and to products produced thereby is described. The method comprises agitating the sewage sludge mixture and waste products with a co-agent to bind the mixture in a mixing chamber (1) having paddles (2). The mixture is fed via a controlled feed (3) to a worm pump (4) leading to the base of cyclone (5) where it is broken down into a coarse particles using air from a blower fan (6). The coarse particled mixture is passed to a cyclone dryer/disinfector (7) for sterilisation by steam from an injector (8). The treated sludge mixture may be fed via a hopper (9) to an auger press (10) from which it is extruded and passed for radiation and sterilisation in a microwave oven (12) and then cut into bricketts. Alternatively, the treated sludge mixture can be passed to hopper (16) via a controlled feed (17) to plank molds (19). The moulds pass under a press (20) to form bio-degradable planks (21) for building shuttering.
