TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The method (M1) involves applying waste heat recovered from the external heat source or another external heat source to the liquid mixture to generate a renewable fuel mixture with ratio of hydrogen to carbon which is higher than hydrocarbon and alcohol produced from the biomass waste dissociation. The method (M1) involves dissociating the hydrogen-dense fuel in presence of waste heat recovered from the external heat source to produce high specific energy hydrogen and carbon monoxide. The hydrogen-dense fuel comprises at least one of hydrocarbon, alcohol and ammonia in method (M1). The hydrocarbon comprises methane. The alcohol comprises methanol. The method (M1) involves transporting the hydrogen-dense fuel to a remote location before applying waste heat to produce high specific energy hydrogen and carbon monoxide. The method (M1) involves transporting the liquid mixture to a remote location before applying waste heat to produce high specific energy hydrogen and carbon monoxide. The method (M1) involves dissociating the biomass waste comprising hydrogen, carbon donors in addition to the hydrocarbon and alcohol. The method (M1) involves reacting the carbon donors with hydrogen produced from biomass waste to generate hydrogen-dense alcohol. The method (M1) involves reacting carbon donors with water to generate additional alcohol. The hazardous contaminant comprises at least one of colloidal carbon, fat, carbohydrate, sugar, rejected waste material from a polymer plant, carbon dioxide from exhaust of an industrial process, dust from coal, dust from grain, dust from polymer processing, and distilled solids from ethanol plant waste stream. The method (M1) further involves filtering out at least one of a halogen and carcinogen from the contaminants. The method (M1) involves dissociating biomass waste to produces wet alcohol that reduces the availability of ethanol. The method (M1) further involves using the wet alcohol as a solvent to dissolve a hazardous contaminant to generate a liquid mixture. EXAMPLE - No suitable example given.
