Methanol is produced from an organic waste material such as sewage by a process wherein an arc heater or “plasma jet”performs novel process steps including: (1) partially vaporizing an organic sewage sludge (a semi-liquid material produced by bacterial digestion of the sewage); (2) reacting the gas products obtained by the sludge vaporization, together with a digester gas (obtained by digestion of the sewage), to form a synthesis gas comprising principally H2, CO, CO2, H2O and CH4, and (3) optionally, driving a water shift reaction to convert a portion of the output gases to additional H2 and CO for use as a feed stream to the jet. The synthesis gas is converted to methanol in a subsequent process step.

The method of producing methanol from organic waste comprising, digesting the waste to produce a digester gas comprising a mixture of CO2 and CH4, and a sludge, supplying said digester gas into the arc of a plasma jet, also supplying H2 and CO gases into said arc, said plasma jet producing a hot output gas stream containing principally H2, CO, and CO2, applying heat from said output gas stream to said sludge to gasify a portion of said sludge, thereby producing a synthesis gas comprising a mixture of H2, CO, CO2, H2O and CH4 as the major components thereof, and an ash residue, and converting said synthesis gas to methanol.
