Abstract
The objective of this work is the management of organic solid waste, rich in organic matter, by anaerobic digestion. The device set up is a batch reactor for the production of biogas. The organic waste used comes mainly from households, consisting of 80.4% organic matter. The anaerobic digestion of this waste gave in 70 days 9 liters of biogas composed of 57.35% methane and 32.4% carbon dioxide. Upgrading of biogas would allow to produce 1235.27 kWh of primary energy per ton of solid household waste treated and to avoid an emission of 6.34 tCO2eq. It would make it possible to avoid 77.54% of the emissions compared to landfilling.
