Hindustan Zinc Limited and Silox India have strengthened their long-term partnership as Silox India adopts Hindustan Zinc’s low-carbon zinc brand, EcoZen, across its manufacturing operations, marking a key step toward industrial decarbonisation in India.
Under the collaboration, Silox India will integrate EcoZen into its zinc-based chemical production, helping lower embedded carbon emissions while maintaining global performance and quality standards. EcoZen is Asia’s first low-carbon zinc produced entirely using renewable energy, with a verified carbon footprint of under one tonne of CO₂ per tonne of zinc—around 75 per cent lower than the global industry average. In downstream applications such as galvanising, its use can help avoid nearly 400 kg of CO₂ emissions per tonne of steel.
Hindustan Zinc, a Vedanta Group company, supplies zinc to sectors including infrastructure, automotive, power, chemicals and renewables. EcoZen forms a core part of its strategy to support customers in achieving Scope 3 emission reductions, aligned with global responsible mining practices.
Silox India said the move aligns with its ESG goals, enabling lower-carbon offerings across its product portfolio. Executives from both companies said the partnership demonstrates how upstream innovation can accelerate sustainability outcomes downstream. Kolkata is seeing a growing demand from eastern India’s chemicals, infrastructure and manufacturing clusters for traceable, low-carbon materials. The adoption of EcoZen is expected to resonate with regional manufacturers and exporters seeking to meet tightening ESG norms and global customer expectations, reinforcing Kolkata’s role as an emerging hub for greener industrial supply chains.
