Udaipur, September 4 (Kiran News): Hindustan Zinc Limited (BSE: 500188, NSE: HINDZINC), India’s only and the world’s largest integrated zinc producer, has achieved a major sustainability milestone by recycling 71 billion litres of treated sewage water between FY2016 and FY2025, thereby reducing its freshwater dependence by 28%. The recycled volume is equivalent to meeting Udaipur’s water needs for more than 500 days.
Operating in water-stressed Rajasthan, Hindustan Zinc has established itself as a 3.32x water-positive company by treating, recycling, and reusing all process water across operations, safeguarding local ecosystems, and reinforcing its commitment to UN SDG 6 (Clean Water and Sanitation).
Udaipur’s First Sewage Treatment Plant under PPP
In partnership with the Government of Rajasthan, Hindustan Zinc set up Udaipur’s first sewage treatment plant (STP) in 2014 under a public-private partnership model. Over the past decade, its capacity has expanded to 60 million litres per day (60 MLD). The plant plays a vital role in preventing untreated sewage from polluting Udaipur’s lakes while supplying treated water through a dedicated pipeline to Hindustan Zinc’s operations.
CEO’s Statement
“Water is a shared legacy, and at Hindustan Zinc, we’ve embraced stewardship that turns challenges into opportunities,” said Arun Misra, CEO – Hindustan Zinc Limited.
