NOVELTY - System (100) for processing organic waste comprises anaerobic bioreactor (110) for fermenting organic waste to generate biogas, where bioreactor includes inlet (1) and outlet (6); fermentation tank (9) disposed between inlet and outlet for fermenting organic waste to generate the biogas; and biogas outlet (4) for outputting biogas generated in the fermentation tank; and aerobic bioreactor covering at least in part the anaerobic bioreactor and containing a further organic waste, which decomposes and thermally regulates the anaerobic bioreactor.    USE - For processing organic waste such as piggery waste and biomass compost material, to generate biogas (claimed).    ADVANTAGE - The fermented or digested waste from the anaerobic reactor is discharged and separated, and the liquid portion undergoes aerobic remediation to reduce the nutrient content and dissolved organic carbon (DOC) in the wastewater; thus allowing the remediated liquid fraction to be discharged safely into the environment. The compost undergoes an aerobic composting process which warms the anaerobic fermentation tank to ensure that an optimum fermentation temperature is maintained in the fermentation tank. The composted biomass can also be removed and used as fertilizer, with new batches of biomass added to the top of the bioreactor to ensure the bioreactor's temperature remains steady.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for processing organic waste involving inputting the organic waste into anaerobic bioreactor for fermenting organic waste to generate biogas; fermenting the organic waste passing through anaerobic bioreactor to generate biogas; outputting the organic waste from anaerobic bioreactor; outputting biogas from anaerobic bioreactor; and thermally regulating the anaerobic bioreactor using decomposing further organic waste in aerobic bioreactor covering the anaerobic bioreactor.
