Cassava processing generates both solid and liquid wastes that are hazardous to the environment. The two important biological wastes that may cause damage to the

environment from this processing activities are the cassava peels and the liquid effluent (wastewater) squeezed out of the fermented mash. The peels are usually discharged on land or water as wastes and allowed to rot in the open thus resulting in health and environmental hazards. The wastewater contains a heavy load of microorganisms capable of hydrolyzing the glucosides. Continuous discharge of this wastewater into the soil for a long period of time leads to the extinction of some bacteria and fungi types that were originally available in the soil. When this effluent is released directly into streams and rivers, it causes rapid growth of bacteria, resulting in oxygen depletion and death of fish and other aquatic life. The wastewater (which contain large amounts of organic compounds) then begin to ferment, emitting methane -
a greenhouse gas whose impact on the climate is 20-times that of CO2.

Our solution addresses this challenge by mitigating its climate-change and environmental pollution effects via the conversion of cassava

wastewater effluent and peels into clean energy in the form of Biogas fuel and Biofertilizer.
