ABSTRACT:
A waste recycling system which separates the reusable components within waste such as tires by incomplete burning followed by a series of separation steps. The incomplete burning is carried out within a chamber having at least two hollow perforated rollers on which the waste is supported. The tires are ignited and caused to smolder within the chamber, allowing gaseous and vapor by-products to be released and travel downward into the rollers. Inorganic solid matter remaining from the combustion process continuously falls between the slowly rotating rollers into a removal bin or conveyor. The gaseous combustion by-products are directed through an oil bath filter having a mesh on which sprayers apply a cooling oil mist to capture the oil vapor. The remaining hydrocarbon emissions are burned incompletely, and the resulting carbon black within the effluent filtered out. The effluent is then completely combusted generating heat and then scrubbed to emit a relatively clean gaseous discharge.
