Description
Summary:This paper examines Municipal Solid Waste (MSW) Management with a high organic matter content employing the Waste and Resource Assessment Tool for the Environment (WRATE) and the Ecoinvent database, by conducting a Life Cycle Impact Assessment (LCIA). Four scenarios, aligned with Algeria’s National Waste Management Strategy, are analyzed as case studies. LCA results identify the baseline scenario (current state) as the worst case. Significant improvements (84% reduction in climate change impact) are observed for scenario 2 to 4, which incorporate methane capture and energy recovery. Likewise, acidification potential was reduced, while eutrophication balanced positively for scenario 1 to 3 and negatively for scenario 4, promoting sustainable practices. This study proposes an optimal solution where the MSW service covers the charges and starts generating profit by shifting from a flat rate of 2000 Algerian Dinars (DZD) per household per year to 1% of household income. This change aims for at least 41% cost recovery from citizens at the national level, with minimum recovery targets for composting (50%), recycling (25%), and efficient landfilling (15%), alongside 20% energy recovery. To align with the Waste Hierarchy priorities, the Algerian government should gradually restrict organic waste landfilling (54% of MSW) and promote composting. Additionally, Algeria should establish regulations to encourage recycling programs, such as implementing Extended Producer Responsibility (EPR) regulations and setting recycling targets for various waste streams.
