摘要

PCT No. PCT/FR97/00316 Sec. 371 Date Dec. 7, 1998 Sec. 102(e) Date Dec. 7, 1998 PCT Filed Feb. 20, 1997 PCT Pub. No. WO97/31120 PCT Pub. Date Aug. 28, 1997The present invention relates to an open circuit organic waste treatment method, to a plant for carrying out the method, and to applications of that method. The treatment method is characterized in that it comprises the following steps: a) collecting the waste; b) introducing the waste into a first reactor without prior sterilisation; c) decomposing the waste in said first reactor using mesophilic or thermophilic anaerobic bacteria; d) recovering the liquid effluent resulting from said decomposition and transferring it to a second reactor containing heterotrophic or photoheterotrophic bacteria; e) using the heterotrophic or photoheterotrophic bacteria to produce an edible biomass constituted by said bacteria; and f) recovering and packaging the biomass produced. A particular application of the method is that of recycling organic waste of animal origin such as liquid manure or sludge originating from water purification.
