Assessing Leachate and Landfill Biogas Generation: Key to Sustainable Waste Solutions

Accurate landfill leachate and biogas production estimation is essential for effective waste management and environmental protection. In this study, we look at the range of techniques available for estimating landfill leachate and biogas production, considering various influencing factors such as waste composition, environmental conditions, and landfill design. Through the practical application of these estimation methods to the Oum Azza landfill, we discovered valuable information about the dynamics of leachate and biogas production at this specific landfill. In particular, our research identified the water balance method as the most accurate and suitable approach for estimating leachate quantities. In contrast, the LandGEM multiphase method was optimal for estimating biogas. The implications of our results go far beyond the scope of this study, as they highlight the profound importance of accurate estimation in the development of sustainable waste management strategies. The insights gained from this research pave the way for designing and implementing waste management practices that are both environmentally friendly and economically viable, thus contributing to a more sustainable and ecologically harmonious future.
