The proposed concept utilises a variety of waste streams from industry thus saving energy and environmental impacts by avoiding manufacture of raw materials. Furthermore as a method of wastewater treatment, en­ergy and associated impacts will be saved by avoiding alternative meth­ods of treatment. The energy recovered through anaerobic digestion or combustion can be returned to the system, powering the units which re­quire an energy source (paddlewheel or centrifugation). The waste heat can be used to dry the biomass if required or alternatively used to heat the ponds if the temperature falls below optimal conditions. The residual waste from the energy recovery system can be fed back into the treat­ment ponds supplying additional nutrients if required or alternatively sold as a fertiliser.
