The ThermoFuel process is a renewable energy process that provides a cost-effective solution for biosolids disposal for municipal wastewater treatment. ThermoFuel integrates advanced primary sludge digestion with hydrothermal treatment of waste activated sludge to expand the capacity of municipal wastewater facilities. This is designed to be a compact, environmentally effective method of upgrading existing wastewater treatment plants to Exceptional Quality ("EQ") Class A biosolids production without the use of storage ponds or lagoons, as is common in some municipal wastewater facilities. EQ Class A biosolids denotes the least health risk of human exposure to biosolids as defined in the 40 CFR Part 503 Risk Assessment study of the US Environmental Protection Agency ("EPA"). Over 95% of all municipal wastewater treatment plants in the U.S. currently produce Class B biosolids that do not meet the required pathogen and vector attraction reduction requirements and as such pose a potential health risk in direct human contact. The high energy and low moisture content of the ThermoFuel make it suitable for use as a fuel substitute or blending agent for power plants, municipal solid waste incinerators, cement kilns, and similar applications.
