Hindustan Zinc Limited (BSE: 500188, NSE: HINDZINC) has signed a Memorandum of Understanding (MoU) with The Energy and Resources Institute (TERI) to develop a 250-hectare ecological restoration project in Rajasthan. The project will be located at Hindustan Zinc's Chanderiya Lead Zinc Smelter Complex in Chittorgarh district and is described as potentially becoming the "world's largest green cover area within industrial premises."

The initiative aims to restore industrial land into a self-sustaining natural ecosystem, enhancing biodiversity and climate resilience. The project will follow a scientific, multi-layered ecological restoration approach comprising native trees, shrubs, herbs and grasses suited to the local landscape. It will include measures for invasive species management, support for water bodies and aquatic ecosystems, and development of long-term maintenance and protection protocols.

This collaboration builds on previous successful restoration work between the companies. At the Jarofix Yard (where residue from zinc smelting is stored), restoration activities covering 22.25 hectares have been completed in two phases, transforming degraded industrial land into ecologically functional and biodiverse green cover. Using TERI's Mycorrhiza technology, this initiative enabled the plantation of nearly 56,400 native trees. A parallel 6-hectare biodiversity park is being developed atop the secured landfill within the complex.

The project supports Hindustan Zinc's Sustainability Goal 2030 focused on halting and reversing biodiversity loss through measurable improvements and working toward delivering a Net Positive Impact (NPI).

CEO Arun Misra stated that sustainability is paramount to company operations, with focus on water stewardship, circularity, decarbonisation and biodiversity conservation. He noted the company is the first Indian company to join the International Council on Mining & Metals (ICMM) and remains committed to global benchmarks in sustainable mining.

The initiative aligns with the company's broader Environment, Social & Governance (ESG) roadmap emphasizing land restoration, biodiversity conservation, water stewardship, decarbonisation and responsible natural resource management.

The disclosure is made in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.
