Abstract This study examines the potential of utilizing calcium carbide residue (CCR) to improve the engineering properties of black cotton soil (BCS) for landfill liner applications, addressing concerns related to municipal solid waste (MSW) disposal. By evaluating the impact of CCR addition on soil character-istics such as compaction behavior and hydraulic conductivity, the research aims to create a tighter packed soil structure, essential for effective landfill liners. Through a combination of BCS and CCR, the study seeks to enhance waste containment while promoting CCR recycling. The primary objective is to investigate the feasibility of the soil-CCR blend as a sustainable solution for waste disposal in India's central region. This research fills a gap in under-standing the combined utilization of BCS and CCR for landfill purposes, contributing to sustainable waste management practices. Furthermore, the study observes a stepwise increase in Optimum Moisture Content (OMC) as CCR content rises, indicating improved moisture retention capabilities of the soil-CCR mixture. The higher OMC values correlate with decreased MDD, signifying a trade-off between soil density and moisture content. This phenomenon suggests that CCR addition not only improves soil engineering properties but also influences its moisture behavior, which is vi-tal for long-term stability and performance as a landfill liner. Moreover, the research anticipates that the incorporation of CCR in BCS will result in a consistent enhancement of shear strength, a critical parameter for landfill liner materials. This improvement in shear strength underscores the potential suitability of the soil-CCR mixture as an effective barrier against the migration of leachate and contaminants, thus minimizing environmental risks associated with waste disposal. Overall, the findings highlight the prom-ising potential of CCR-modified BCS as landfill liners, offering improved engineering properties and environmental benefits. The observed trends in compaction behavior and moisture content signify the positive impact of CCR addition on soil stabilization, paving the way for further research and development in sustainable waste management practices. Future investiga-tions will delve into detailed material mixes to elucidate the extent of en-hancement in soil properties and validate the suitability of the soil-CCR mix-ture for landfill liner applications. As the Optimum Moisture Content (OMC) increases, the Maximum Dry Den-sity (MDD) decreases with an increase in the percentage of CCR. This study anticipates that adding CCR to BCS will lead to a denser soil structure and potentially lower hydraulic conductivity. Moreover, the soil-CCR mixture is expected to show significant improvement in shear strength, making it suita-ble for landfill liners. More testing will be done to confirm these results and see how different mixtures perform.
