<p>PROBLEM TO BE SOLVED: To provide a method for producing a fuel from a biomass, in more detail, a method for producing the fuel such as ethanol and methane by using minute algae, and weeds and crops as raw materials, degrading the raw materials in supercritical water to reduce the molecular weights, and carrying out alcohol fermentation of the degraded raw materials by alcohol yeast or methane fermentation thereof by gasification bacteria. SOLUTION: This method for producing the fuel from the biomass comprises collecting the biomass, pulverizing the collected biomass, adding water to the pulverized product to form a slurry, keeping the resultant slurry in the subcritical state or the supercritical state to degrade polysaccharides included in the biomass to saccharify the polysaccharides, and fermenting the saccharified product to produce the objective fuel.</p> |
