Different categories of wastes and residues generated during cassava processing must be properly managed so as not to constitute environmental hazard. The huge cost of treatment and disposal create avenue for alternative uses to be explored. This study reviewed the various value added products which can be produced from cassava wastes substrate as feed-stock for bio-energy. Theoretically, it was estimated that one kilogram of cassava peelings will yield 118 g of bio-methane and 226 g of bio-ethanol, one litre of cassava wastewater will yield 16 g and 9 g of bio-ethanol and bio-methane, respectively whereas 20 g and 10 g of bio-ethanol and bio-methane, respectively will be obtained from one litre of bagasse. These was also compared with the estimated values obtained based on Chemical Oxygen Demand (COD):23.9g of CH4/gCOD in one litre of cassava wastewater, Volatile Solids (VS):23.1g of CH4/gVS in one litre of cassava wastewater and Total Solids (TS):22.9g of CH4/gTS in one litre of cassava wastewater and 0.414g using Buswell’s equation. This is study can be utilized when making decision on the potentials of cassava wastes for value added products. Keywords: Cassava, wastes, bioenergy, bioethanol, biomethane
