| 28. 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 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 waste material feedstock is contacted with the exhaust gases at a waste generation site to voiding significant decomposition
of the waste material feedstock.
