Landfill gas mitigation using steel slag as a Biocover – A case study

This study explores the potential of use steel slag as a biocover for dumpsite gas mitigation. Landfill sites are significant sources for greenhouse gases (GHGs), particularly methane (CH₄) and carbon dioxide (CO2), which contribute to global warming and create environmental and health problems. This study explores the potential use of steel slag, an industrial byproduct, as an alternative bio cover material for LFG emission control and the study found that steel slag achieved a higher carbon dioxide reduction efficiency compared to soil covers. This research highlights the dual benefits of utilizing steel slag for gas control and promoting sustainable waste management by reuse of industrial byproducts. Based on the series of batch test slag showed sequester of 64.10mg/g carbon dioxide at moisture condition tested in 24hours. The primary objective of this study is to know the feasibility of using steel slag as a biocover material for mitigating gas emissions from landfills. This study aims to provide an alternative, cost-effective, and sustainable solution for landfill gas management while addressing the issue of industrial waste utilization, this work concludes that steel slag is a promising alternative biocover material for landfill gas mitigation.
