1. A Fisher-Tropsch liquid fuel derived from biogenic carbon materials obtained solely from processed municipal solid wastes, the fuel derived from a process comprising the steps of:

  • a) in a feedstock processing step, removing non-biogenic derived carbon materials and non-carbonaceous materials from municipal solid wastes (MSW) that contain materials that are produced from plant derived carbon (biogenic) as well as non-biogenic derived carbon (fossil based) materials, to produce a processed MSW feedstock that contains a greater concentration of biogenic carbon than non-biogenic carbons along with other non-carbonaceous materials from the municipal solid wastes; and

    b) converting the processed MSW feedstock into Fischer-Tropsch liquids in a bio-refinery while maintaining the concentration of biogenic carbon up to 90% from the processed MSW feedstock.
