Zusammenfassung:The invention relates to a process for the treatment of biomasses, e.g. sludges produced during biological purification of effluent, manures, and other microbiological or cultured biomasses. According to the invention the biomass is treated, with or without, pretreatment by temperature-pressure hydrolysis (TPH) at 150 to 300 DEG C, preferably at 180 to 300 DEG C, in a single- or multi-step hydrolysis system, with or without the use of inorganic catalysts such as Ca, Na and K, a residual mass being produced as a solid phase and a liquid phase enriched with valuable organic monomeric materials.
