Abstract:
Abstract: This study presents an inclusive review and proposed design for a modern, environmentally friendly landfill utilizing an advanced lining system to mitigate the environmental impacts of municipal solid waste (MSW). The research focuses on the implementation of a dual-liner system, combining bentonite clay for its high absorption capacity with a high-density polyethylene (HDPE) membrane, to prevent leachate leakage and groundwater contamination. The design also incorporates a gravel layer with embedded pipes for efficient leachate collection, directing it to a treatment facility for purification. Daily soil cover is applied to minimize odors and pests, while a final capping system, including a geomembrane and soil layer, ensures long-term environmental protection.
The study highlights the urgent need for sustainable waste management solutions in Sirte, Libya, where uncontrolled dumping poses significant health and environmental risks. By analyzing climatic conditions, waste composition, and population growth projections, the proposed landfill design addresses local challenges while adhering to international standards. Key outcomes include reduced greenhouse gas emissions, minimized leachate infiltration, and the potential for land reclamation post-closure, transforming the site into usable green spaces.
