摘要： A production process for producing biogas by means of anaerobic co-digestion which includes (a) preparing hydrolyzed biomass from organic solid waste by means of a thermal hydrolysis treatment of waste at between 1.5 and 4.5 bar and between 120 and 160° C., generating raw biomass from which foreign matter is separated, giving rise to clean hydrolyzed biomass with at least 90% organic matter, a volatile solids to total solids ratio of at least 0.6 and at least 5% total solids; (b) mixing the clean hydrolyzed biomass with sludge from a wastewater treatment plant (WWTP), generating a mixture with a concentration of solids of less than 30% which is conditioned to a concentration of less than 20%; and (c) a step of wet anaerobic digestion in a digester at between 25° C. and 40° C. or between 50° ° C. and 60° C. and during an HRT of between 12 and 30 days, generating biogas and a digestate.

摘要： The present invention relates to a method for municipal solid waste (MSW) reclamation in a continuous or discontinuous process first for converting said waste into organic biomass and subsequently extracting and recovering the most chemical compounds contained in said biomass possible, such as triglycerides, sugars and proteins. Therefore, the invention is comprised in the field of recycling, transforming solid waste into reusable solids and biofuels.
