<p>The invention concerns a method for treating sludge, grease and other waste material derived from domestic and industrial wastewater treatment, characterized in that the sludge, grease and other waste material are subjected to an enzymatic treatment, in the absence of aeration, instead of hydrolysis and acidification steps prior to methanization for digesting the sludge, said treatment, producing hydrolysis of the sludge, being carried out by combining pluri-enzymatic combinations selected in accordance with the composition of the sludge to be treated, the reaction pH and temperature corresponding to optimal use values of the selected enzymes.</p> |
