Abstract
The objective of this study is the treatment and energy recovery from household waste, rich in organic matter, by anaerobic digestion, to counteract the harmful effects of pollution and produce a green energy that is biogas. Anaerobic digestion offers multiple benefits to its increasing use. In the case of waste from the landfill, it enables the reduction of odors and the reduction of the volume of waste discharged. During this experiment we took a mass of fermentable waste from the landfill which was finely divided and mixed with water with a dilution rate of 80%. The biogas produced at the end of digestion, has a fairly good yield (50% -60%) and a volume of the order of 400 mL for a residence time of less than 25 days, this is due to the biodegradability of this substrate. This biogas is flammable, these satisfactory and encouraging results, confirms to us, that the energy recovery of organic waste from the dump is a very good alternative of pollution control.
