Fuel composition comprised of heat-treated dewatered sewage sludge and a biocide-containing fuel oil
An improved fuel composition is described comprised of a colloidal dispersion of a sewage sludge in a fuel oil. The composition consists of (1) from about 20 to 70 percent by weight of a heat-treated dewatered sewage sludge comprising from about 50 to 85 percent by weight of water with the remainder comprising solids, the sewage sludge having been heat-treated under conditions effective to substantially reduce the microorganism activity within the composition while maintaining the water content of the sewage sludge within the range, and (2) from about 30 to 80 percent by weight of a fuel oil containing a biocide which is at least oil soluble or dispersible in an amount effective to inhibit the growth of microorganisms within the composition.
