Lab-scale anaerobic digestion of cassava peels: the first step of energy recovery from cassava waste and water hyacinth.

Cassava processing in Republic of Benin, which is used to produce different food products, discharges a large amount of polluting organic matter into the environment in the form of peels and wastewater. Besides, water hyacinth a rich nitrogen plant invades Benin water streams leading in aquatic ecosystem asphyxia and blocks the navigation. Both cassava wastes and water hyacinth show a high biodegradable content enable to be treated through anaerobic digestion.
