Valorization of Household Waste in Algeria Using the Methanization as a Source of Renewable Energy

Currently, the release of gases from landfills constitutes a substantial contributor to air pollution. It is of paramount importance to reduce and efficiently utilize these gases, considering their significant implications for both public health and the global environment. Methanization represents a substantial opportunity as a clean and sustainable energy source. It contributes significantly to lowering greenhouse gas emissions, improving waste management efficiency, and generating renewable energy. This process plays a crucial role in the transition toward more environmentally friendly and sustainable energy systems. The objective of our study is to assess the quantity of biogas (specifically methane) generated at the Algerian landfills using the different mathematical models. Our findings, as derived from the models, indicate a substantial release of biogas, which contributes to the issue of global warming. This energy loss is quantified and it possesses the potential to be converted into electricity. Consequently, this conversion could render the landfill self-sufficient in terms of electricity production, serving as an economically viable energy source while simultaneously reducing greenhouse gas emissions.
