NOVELTY - The method comprises: drying sludge; transferring the sludge to an extractor (117) containing a predetermined level of heated solvent; continuously adding the solvent to maintain the predetermined level of the solvent; separating miscella from the sludge leaving solids using the solvent; transferring the miscella to an evaporator (131); separating the solvent to the extractor; removing residual solvent from the solids; drying the solids; and recycling the solvent to the extractor. The miscella is an oil/solvent mixture.    USE - The method is useful for reclaiming usable products from a sludge (claimed), where the sludge is useful for biodiesel production and the products include an oil and a fertilizer.    ADVANTAGE - The method enables efficient recovery of the solvent in an economical manner thus producing a clean, environmentally friendly fertilizer.    DETAILED DESCRIPTION - The method comprises: drying sludge; transferring the sludge to an extractor (117) containing a predetermined level of heated solvent; continuously adding the solvent to maintain the predetermined level of the solvent; separating miscella from the sludge leaving solids using the solvent; transferring the miscella to an evaporator (131); separating the solvent to the extractor; removing residual solvent from the solids; drying the solids; and recycling the solvent to the extractor. The miscella is an oil/solvent mixture. The method further comprises separating oil from the oil/solvent mixture at the evaporator, separating 80-90% of the solvent from the oil/solvent product utilizing waste heat from the extractor, condensing vapors from the evaporator, and separating water from the solvent. The solvent includes non- polar or polar aprotic solvents. A time period of the sludge contacting the solvent is maintained to produce a concentration of 5-25% oil in the solvent, and is sufficient to produce a solvent content of the solids upon exiting the extractor that is less than 30% of the solvent. The sludge is dried to a moisture content of below 10-15%, and is immersed in the solvent during separation of the solids and non-solids. The sludge within the extractor flows from a first end to a second end and counter-current to a flow of the solvent such that miscella is removed near to solids inlet at the first end. The solvent is present in fed at the second end opposite to the counter-current flow with solvent vapors that are removed between the first end and the second end. The solids are immersed in the solvent during counter-current flow of solids and solvent. The extractor maintains the solvent below the boiling point of the solvent of 10-20 degrees F. The method comprises transferring the solid to a desolventizer (121) to remove solvent from the solids, drying the desolventized solids, and transferring the oil/solvent mixture to another evaporator until the oil/solvent mixture reaches 97% of oil. The solids are dried to a moisture content of 10%. The oil is extracted from the solvent in an oil stripper (141). The solids are used as a fertilizer meeting Class A Exception Quality Biosolids in accordance with Code 40 CFT part 503. An INDEPENDENT CLAIM is included for a method for producing fertilizer.
