Abstract:
An open circuit method for converting organic waste into an edible biomass, comprising the steps of:a) collecting said organic waste;b) introducing said organic waste into the vessel of a first reactor without prior sterilization;c) decomposing said organic waste in the vessel of said first reactor by mesophilic or thermophilic anaerobic bacteria for a time sufficient to convert said organic waste into a liquid effluent containing carbonaceous and nitrogenous compounds assimilable by heterotrophic or photoheterotrophic bacteria;d) recovering said liquid effluent;e) transferring said liquid effluent to the vessel of a second reactor;f) culturing heterotrophic or photoheterotrophic bacteria in the vessel of said second reactor whereby an edible biomass is produced by assimilation of the carbonaceous and nitrogenous compounds present in said liquid effluent by said heterotrophic or photoheterotrophic bacteria;g) recovering said edible biomass; andh) packaging said edible biomass.
