NOVELTY - Transforming waste organic material to produce a liquid transportation or heating fuel, involves: (a) subjecting waste organic material to anaerobic digestion; (b) collecting crude biogas; (c) removing impurities from the crude biogas; (d) introducing combustible fluid feedstock from the step (b) or (c) to a fuel production facility; (e) withdrawing combustible fluid feedstock; (f) processing combustible fluid feedstock to produce renewable hydrogen; (g) producing liquid transportation or heating fuel; and (h) generating or causing generation of a renewable fuel credit.    USE - The method is useful for transforming waste organic material to produce a liquid transportation or heating fuel, including gasoline, diesel, heating oil or jet fuel (all claimed), where the fuel is useful in automobiles.    ADVANTAGE - The method is capable of efficiently transforming waste organic material in a simple and cost-effective manner.    DETAILED DESCRIPTION - Transforming waste organic material to produce a liquid transportation or heating fuel, involves: (a) subjecting waste organic material to anaerobic digestion by microorganisms in a biogas production facility that incorporates apparatus to collect the microbially generated biogas; (b) collecting an amount of crude biogas from the biogas production facility; (c) removing impurities from the crude biogas to yield a combustible fluid feedstock; (d) introducing a first amount of combustible fluid feedstock from the step (b) or (c) to apparatus for delivering a combustible fluid feedstock to a fuel production facility; (e) withdrawing for use at a fuel production facility a second amount of combustible fluid feedstock; (f) processing at the fuel production facility the second amount of combustible fluid feedstock to produce renewable hydrogen; (g) producing a third amount of liquid transportation or heating fuel by a process that comprises combining renewable hydrogen derived from the second amount of combustible fluid feedstock with a desulfurized, crude oil derived liquid hydrocarbon in a reactor under conditions to hydrogenate the liquids hydrocarbon with the renewable hydrogen; and (h) generating or causing generation of a renewable fuel credit.
