NOVELTY - A formate produced by reacting hydroxide on carbon monoxide obtained by carrying out partial-oxidation processing of organic waste material is used as snow-melting agent, flower thinning agent, photo-oxidation disorder preventing agent or fertilizer, or aqueous solution of the formate is used for direct formate fuel-cell electric power generation. The strong base emitted during electric-power generation is recovered. Thus, circulation of resource is enabled. The apparatus used for formate synthetic reaction is also claimed.    USE - For circulating resources for direct formic acid fuel cell for electric power generation for motor vehicle, household appliances, robots and ships, and for soil improvement material and fertilizer.    ADVANTAGE - The method enables effective and efficient circulation of resources and suppression of environmental pollution.    DETAILED DESCRIPTION - A formate such as sodium formate, potassium formate and calcium formate produced by reacting sodium hydroxide, potassium hydroxide or calcium hydroxide at high temperature and high pressure on carbon monoxide obtained by carrying out partial-oxidation processing of organic waste material (combustible waste material) at high temperature is used as a snow-melting agent, flower thinning agent, photo-oxidation disorder preventing agent or fertilizer, or aqueous solution of the formate is used for direct formate fuel-cell electric power generation. The strong base simultaneously emitted during electric-power generation is recovered. Thus, circulation of resource is enabled. The apparatus used for formate synthetic reaction is also claimed.    INDEPENDENT CLAIMS are included for the following:    (1) method and apparatus for manufacturing fertilizer, soil improvement material and other fermentation production using the fermented-liquor residue produced after hydrogen-formic acid fermentation;    (2) suppression of carbon dioxide emission; and    (3) electric power or gasoline-station state power station, which carries out battery supply to motor vehicle which does not have fuel cell and which has charger mounted as electric power source and which effectively uses the electric power generation by the resource circulation method.
