This study explores the integration of nanotechnology in the leather industry, especially on leather manufacturing, a sector historically recognized by significant environmental challenges. Traditional leather manufacturing, while economically substantial, contributes to extensive pollution and waste as well as greenhouse gas emission. This research examines the application of nanomaterials across various leather manufacturing stages, aiming to mitigate ecological impacts. The findings reveal that nanomaterials enhance eco-friendly curing and tanning processes, reducing reliance on harmful chemicals, huge amounts of water, and pollutants. Innovations in beam house operations and finishing techniques are highlighted, where nanotechnology introduces functional properties such as antimicrobial and self-cleaning features. The study also emphasizes waste reduction and the promotion of a circular economy through efficient recycling and repurposing of leather waste. The implementation of nanosensors ensures quality control and resource efficiency. Overall, the research underscores nanotechnology’s pivotal role in steering the leather industry toward sustainable practices and net zero goals, enhancing its global competitiveness and environmental responsibility.
