Anaerobic digestion is a natural process of transforming organic matter into energy by methanogenic bacteria. This process is performed in the digesters in the absence of oxygen, they produce biogas composed mainly of methane (CH4) which is a combustible natural gas we can used in everyday life. In this work, we produced biogas using a continuous digester with a capacity of 4m3 and after the biogas purification; we used methane produced to run the generator to produce electricity. The results are very encouraging, where we have to produce electricity and cover the daily needs of the Algerian individual in electricity using 1m3 of biogas from our digester
