摘要: Method for the continuous production of hydrogen (H2) and methane (CH4) from zootechnical effluents, comprising steps of: in a first tank (SI), preparing feeding mixture containing effluents agro-food wastes rich fermentable molecules, which include substance carbohydrates consisting whey, scotta or glycerol; bioreactor (Bl), causing fermentation said mixture, under anaerobic conditions, darkness controlled temperature, pH pressure, by means inoculation mesophilic microorganisms promoting phase hydrolysis, acidogenesis acetogenesis, order to produce H2, acidic wherein step (Bl) is obtained at subatmospheric pressure; second (B2), methanogenic digestion fermented broth resulting temperature pH, methanogenesis, CH4, neutral conditions; introducing into (B2) least part H2 produced CH4 (B2); controlling composition accordance with quantities be obtained.
