The worldwide leather tanning industry is crucial in global trade, making around US$50 billion in sales. However, its fast growth has caused significant environmental issues, prompting a careful reconsideration of the industry's operation. Tanneries, often situated near the water, highlight the difficulty of balancing making money with caring for the environment. Having good plans for managing waste is crucial to deal with these issues. Leather Working Group (LWG) certification is a way to transform the industry. Getting LWG certification allows tanneries to sell their products to the EU and other places that care about the environment. However, there are challenges for tanneries trying to get this certification. This study uses a Multi-Criteria Decision-Making tool to prioritize these challenges systematically. By focusing on these obstacles, the research aims to help the industry move towards more sustainable practices, ensuring it stays competitive globally while taking care of the environment.
