NOVELTY - Converting biosolids into fuel comprises providing biosolids containing cells and cell-bound water; applying pressure to biosolids to maintain liquidity; heating pressurized biosolids to rupture cells and free cell bound water to form ruptured biosolids cells slurry; depressurizing slurry of ruptured biosolids cells; and removing a portion(s) of freed cell-bound water from the slurry to provide (partially) dewatered ruptured biosolids product.    USE - The invention is useful for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering.    ADVANTAGE - The invention provides an environmentally acceptable disposition of biosolids, as well as energy for various energy consumers, e.g. cement kilns and electric power plants. It provides increases in the availability and environmental acceptability of renewable fuels. It minimizes wastes to be land filled. It reduces the moisture (water) content of waste going to landfill. It reduces fouling and slagging. It provides fuel that is compact and easy to store and transport. It provides sterile fuel that is storable without deterioration. It provides economical ways of co-firing a non-compliant fuel. It reduces disposal costs. It can be used for fertilizer. It is free of odors, as well as harmful substances, e.g. viruses or pathogens.    DETAILED DESCRIPTION - Converting biosolids into a fuel comprises providing biosolids containing cells and cell-bound water; applying pressure to the biosolids to maintain liquidity; heating the pressurized biosolids to a first temperature to rupture cells and free the cell bound water to form a slurry of ruptured biosolids cells; depressurizing the slurry of ruptured biosolids cells; and removing a portion(s) of the freed cell-bound water from the slurry to provide (partially) dewatered ruptured biosolids product.
