Hindustan Zinc Limited and Silox India have strengthened their long-standing partnership with the adoption of Hindustan Zinc’s low-carbon zinc brand, EcoZen, across Silox India’s manufacturing operations. The move marks a key step in advancing low-carbon manufacturing practices and underlines the role of upstream material producers in enabling downstream decarbonisation across India’s industrial value chains.

EcoZen is Asia’s first low-carbon zinc produced entirely using renewable energy and carries a verified carbon footprint of less than one tonne of CO₂ per tonne of zinc—around 75% lower than the global industry average. The product also offers full traceability and third-party verification, allowing customers to transparently account for the environmental impact of their raw material choices. In downstream applications such as galvanising, EcoZen can help avoid nearly 400 kg of CO₂ emissions per tonne of steel compared with conventional zinc.

A Vedanta Group company, Hindustan Zinc supplies zinc to a wide range of sectors including infrastructure, automotive, power, chemicals and renewables. As part of its sustainability strategy, the company has focused on reducing emissions across its own operations as well as customer value chains. EcoZen plays a central role in this approach by supporting customers in achieving Scope 3 emission reduction targets. Hindustan Zinc is also a member of the International Council on Mining and Metals (ICMM), reflecting its alignment with global standards on responsible mining and climate action.

Silox India, a key customer of Hindustan Zinc in chemical applications, specialises in inorganic chemistry and non-ferrous metal derivatives. By integrating EcoZen, the company aims to reduce the embedded carbon footprint of its zinc-based products while maintaining performance and quality standards for global markets.

“Decarbonisation at Hindustan Zinc is not limited to our own operations; it extends to how our products are used across industries,” said Arun Misra, Chief Executive Officer & Whole-time Director, Hindustan Zinc. “EcoZen represents a step change in how zinc can support cleaner manufacturing.”

Prakash Raman, Managing Director, Silox India, said, “Integrating EcoZen into our manufacturing processes allows us to lower embedded emissions across our product portfolio while continuing to deliver high-performance solutions to our customers.”

The collaboration highlights how cross-value-chain partnerships can accelerate India’s transition towards a more sustainable industrial economy.
