Hindustan Zinc Limited will collaborate with Tata Steel Limited to expand the use of EcoZen zinc in steel manufacturing, the companies said. The partnership is intended to test and scale a low-carbon galvanising solution across selected steelmaking processes, with Hindustan Zinc Limited referred to as HZL and Tata Steel Limited as Tata Steel in subsequent references. The move is aimed at reducing embodied carbon in coated steel products and at promoting cleaner input materials across supply chains.

The firms plan to evaluate process compatibility, environmental impact and commercial viability through joint trials and shared optimisation work. HZL will supply low-carbon zinc and will work with Tata Steel engineers to adapt galvanising lines, and Tata Steel will assess coated product performance and market acceptance. The collaboration will also explore traceability features to assure buyers about material provenance and carbon credentials.

Industry observers noted that zinc coating is widely used to protect steel from corrosion and that lower carbon inputs can reduce lifecycle emissions for infrastructure and automotive applications. The partnership aligns with broader decarbonisation efforts within heavy industry where material substitution and process innovation are being prioritised. By combining mining and processing expertise with steelmaking capabilities the collaboration seeks to create demand for lower carbon zinc and to incentivise upstream improvements.

The companies indicated that initial work will focus on trials and scaling in domestic plants with potential to extend to export supply chains subject to market response and regulatory approvals. Company executives signalled that success could encourage similar partnerships and help meet corporate sustainability targets while offering steelmakers a lower carbon coating option. The initiative is expected to progress over the coming months with detailed commercial terms and timelines to be finalised as trials conclude.
