Leathercrete-A Sustainable Approach to Fine Aggregate Replacement

Concrete is the most utilized construction material globally, owing to its abundance, durability, extended lifespan, high resilience, and countless applications. Conversely, its extensive usage has considerable environmental implications, including increased carbon emissions and the exhaustion of natural resources. Thus, at the turn of the century, the demand for new building ideologies that incorporate sustainable construction practices—that is, emphasizing sustainable construction while maintaining performance standards—has increased [23]. Worldwide, the increased amount of waste generation from leather industries presents an opportunity to develop a sustainable alternative. This study analyses the feasibility of using leather waste as a partial or complete replacement for fine aggregate in concrete by evaluating its mechanical properties, environmental impact, and economic viability. The findings highlight the potential of leathercrete as an eco-friendly alternative to conventional concrete, reducing waste accumulation and conserving natural resources.
