An open-circuit organic waste processing method, a plant therefor, and the uses of said method, are disclosed. The processing method comprises (a) collecting the waste, (b) feeding the waste into a first reactor without prior sterilisation, (c) decomposing the waste in said reactor by means of mesophilic or thermophilic anaerobic bacteria, (d) recovering the resulting liquid effluent and transferring it into a second reactor containing heterotrophic or photoheterotrophic bacteria, (e) using the heterotrophic or photoheterotrophic bacteria to produce an edible biomass consisting of said bacteria, and (f) recovering and packaging the resulting biomass. The method is particularly suitable for recycling organic animal waste such as liquid manure or water purification sludge. |
