A green leather processing technology and keratin biomass recycling system to address the challenges faced by tanneries in Kenya. The traditional use of toxic chemicals in leather processing is no longer sustainable due to pollution concerns and strict government regulations. Dr. Wanyonyi's innovative biotechnology process ensures environmental protection and zero waste discharge, providing high-quality leather production without health risks. By introducing eco-friendly chemicals and biotechnology, this technology benefits both tanneries and end users by eliminating pollution, reducing waste management costs, and producing high-quality leather products. The bio-valorization of tannery waste streams enhances resource recovery and contributes to employment creation, wealth generation, and a cleaner environment.
