NOVELTY - Processing of organic waste materials comprising dewatering the comminuted material, fermenting the water to produce biogas, carbonizing the solids to produce process gas, size-fractionating the char, and steam reforming the fine char fraction and process gas, is new.    USE - The process is useful for converting organic waste materials, especially refuse, wood, garden waste, food waste, hydrocarbons and/or organic compounds, into fuels (especially hydrogen, biogas and methanol), electricity and fertilizer.    DETAILED DESCRIPTION - Processing of waste materials comprising biogenic materials and/or hydrocarbons or other organic compounds to convert carbonaceous materials into fuels, electricity and fertilizer comprises:    (i) comminuting and mixing the materials;    (ii) dewatering the comminuted material;    (iii) fermenting the water in one or more reactors and passing the resulting biogas to a power station and/or a pressure reactor;    (iv) heating the solids to 450-480 degrees Centigrade in a low-oxygen atmosphere to produce process gas and a dry residue;    (v) separating the dry residue into a coarse fraction comprising mainly ferrous and nonferrous metals and inert minerals and a fine fraction comprising more than 99% solid carbon; and    (vi) passing the fine fraction and process gas to a pressure reactor.    An INDEPENDENT CLAIM is also included for the apparatus for carrying out the process, comprising a combination of at least one conversion or carbonization apparatus, at least one fermentation reactor, at least one power station and at least one pressure reactor.    DESCRIPTION OF DRAWING(S) - The drawing shows an installation for carrying out the process, comprising a material receiving bay (A), a sorting and processing unit (B), a power plant for internal heat supply (C), a synthesis gas processing unit (D), a power plant for electricity generation (E), a fertilizer processing unit (F), working and laboratory space (G), a 4-stage biogas fermenter (H), office and recreational space (J) and a thermal sludge dewatering unit (K).
