<p>A process for producing methane from process water and biogenic material such as that occurring in the production of sugar and ethanol, wherein at least one mixing/preliminary tank is supplied with process water and biomass, and optionally with washing and/or fresh water and/or substrate water to produce a mash, the mash is set to a suitable pH value and temperature. The mash is transferred into at least one bioreactor with anaerobic methane bacteria for biogas production, the biogas developed is extracted and the biodegraded fluid is drawn off. A biogas plant for performing this process has at least one mixing or preliminary tank for mash provided with a heat exchanger system, and at least one downstream biogas reactor having bacteria producing biogas. The biogas plant is used for producing biogas and storing waste and process water and by-products from the sugar and ethanol production operation.</p> |
