Patent ·
OSTI ID:5007032

A process is described for the chemical treatment of organic waste materials contaminated with a pathogenic microorganism, such as raw sewage, sewage sludge and other organic waste products, and to the treated organic waste material so obtained. The process comprises pre-reacting the organic waste material with a water-soluble methylol compound subject to condensation, such as a methylolurea compound, under alkaline pH conditions; and, thereafter, condensing the methylol compound by establishing an acid pH condition to form a solid waste product comprising a condensation polymer containing methylene bridges and a sterile solid waste material.
