Immobilization of Heavy Metals Present in Biomedical Waste Ash by Using Sulphur Based Geopolymer Concrete – A Review

Bio-Medical Waste Ash (BWA) is a hazardous waste substance having extensive potential to cause significant health detriments to both the environment and individuals, including cancer, genetic risks, early mortality, and chronic diseases. This debris is relegated to landfill, resulting in the contamination of subterranean water and the ecosystem. The optimal method for disposing of BWA is to repurpose it into a construction material, hence mitigating dangerous toxic substances. The potential use of Bio- Medical Waste Ash (BWA) as a replacement for Ground Granulated Blast Furnace Slag (GGBS) in Geopolymer Concrete (GPC) has been untouched in the research. Research has been conducted on the utilization of Geopolymer Concrete (GPC) in conjunction with BWA to develop a novel kind of Green Concrete. The substitution of BWA in geopolymer concrete demonstrates improved mechanical characteristics. The results indicated from the review is that BWA might serve as a partial substitute for the raw material in Geopolymer Concrete. This research may aid in diminishing hazardous BWA as a construction material.
