Biogenic Refinery with SCR System Using Urea Extracted from Feedstock

A method involves the processing of a feedstock comprising sanitary products with human waste in a biogenic refinery. The feedstock is shredded to reduce a particle size of the feedstock. The liquid and solid components of the feedstock are separated and the solid components are transferred to a conveyor and moved on a conveyor to a pyrolysis pot of the biogenic refinery. The solid components are heated in the pyrolysis pot to generate an exhaust. The exhaust is directed to a plenum that extends, respectively downstream, to a pollution control device and a heat exchanger. The liquid components are directed through a heat exchanger of the biogenic refinery. The liquid components are heated, concentrated, and injected into the exhaust in the plenum prior to the exhaust flowing to the pollution control device.
