Bio-methanisation potential (BMP) test for organic waste available in the south region of Tunisia

Driving into renewable energy production from organic resources and wastes becomes the most effective solution to cover the energy demand and to reduce the environment issues. Recent studies report that anaerobic digestion, especially the co-digestion, is an efficient alternative technology that combines bio-energy production with sustainable waste management. Tunisia is one of the countries which suffer from energy demand problems and environment issues. Thus, Tunisian government turns on the development of renewable energy. Therefore, this study focuses on the evaluation of biogas and bio-methane yield from the co-digestion of three available and abundant bio-wastes in the south regions of Tunisia. In this context, bio-methanisation potential test (BMP) was carried out to this evaluation. As a result, the biogas and bio-methane cumulative were respectively equal to 0.263 Nm3 biogas/ Kg VS, 0.166 Nm3CH4/Kg VS for bottle 1 and 0.134 Nm3biogas/ Kg VS, 0.069 Nm3CH4/Kg VS for the blank. This test gave volatile solids reduction equal to 98.99% and 96.81 %.
