Make Environment Save

Our Mission

To identify, evaluate, and implement initiatives targeting the conversion of leather industry waste into valuable byproducts. Additionally, we aim to optimize water efficiency and reuse treated water for industrial purposes while upholding sustainability within the tanning industry.

Our Vision

Our vision is to safeguard the environment and promote the leather industry by supporting the implementation of modernization and technological advancements. We aim to enhance occupational safety and health standards in factories and ensure the protection of public health.

As global awareness of environmental issues grows, NGOs and social activists are increasingly influential in advocating for the environment and the rights of individuals. In Tamil Nadu, the vigilant Tamil Nadu Pollution Control Board and the judiciary play crucial roles in enforcing pollution control laws and addressing environmental concerns. The leather processing industry is often cited for its environmental impact, as the process of turning raw hides into finished products generates both solid and liquid waste that must be treated to meet environmental standards. CEMCOT is committed to addressing these challenges through innovative solutions and sustainable practices.
