Patent ID: 7487601

Claim:
A method for treatment of waste material feedstock comprising: operating a gas turbine generator to produce electricity and exhaust gases having a temperature greater than 1,000° F.; contacting the exhaust gases having a temperature greater than 1,000° F. directly with waste material feedstock having a moisture content of at least 30% by weight in a dryer vessel for a contact time sufficient to produce without significant pyrolysis of the waste material feedstock a dried material having a moisture content of less than about 20% by weight; granulating, pelletizing or prilling the dried material to produce a dried solid food product, a dried solid fertilizer product or dried solid soil builder product suitable for conventional dry product handling, transport or use; and wherein plant or animal nutrient values in the dried material are maximized by avoiding significant composting or digestion of the waste material feedstock prior to contacting the waste material feedstock with the exhaust gases.
