The invention relates to a method for treating organic waste, in particular to a method for treating sludge from wastewater treatment plants, in order to produce power and/or hygienized organic matter, including a first step of mesophilic or thermophilic digestion ( 13 ) of at least one fraction of a stream of organic waste, and comprising the following steps: dehydrating ( 15 ) all of the digested and non-digested waste; aerated thermal hydrolysis ( 16 ) of the dehydrated waste, including an injection of an oxidizing agent in a quantity lower than the stoichiometric quantity for oxidizing organic matter, and setting to the required temperature by a heating means; and a second mesophilic or thermophilic digestion ( 17 ) of the stream of hydrolyzed waste. |
