Abstract
This invention discloses systems and methods for conversion of high moisture waste materials to dry or low moisture products for recycle or reuse. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel and wherein the processing unit forms the dried material from the dryer vessel into granules, pellets or other desired form for the final product. Optionally, the systems and methods further provide for processing ventilation air from manufacturing facilities to reduce emissions therefrom.

57. A method for reducing atmospheric release of emission gases from a manufacturing operation comprising:
-
enclosing at least a portion of the operation that produces emission gases to contain the gases;
directing at least a portion of the gases to a combustion air intake of a gas turbine, oil or gas burner or a reciprocating engine;
directing at least a portion of the exhaust gases from the turbine, burner or engine to a dryer vessel for drying or treating a waste material feedstock. - View Dependent Claims (58, 59)
