Fumer Technology: Gainful waste utilisation
While mining brings employment, government revenues, and opportunities for economic growth and diversification, it also impacts the environment we live in. At Hindustan Zinc, we conduct our business in a responsible manner and in a way that has minimal environmental and social impact. Technology and innovation have been integrated in to the way we conduct our business strategy which ultimately enables us to sustain long-term stakeholder value.
Both our products and processes have sustainability at their core. Our products - Zinc, Lead and Silver - help us in protecting the environment and minimising any negative impact. Zinc prolongs the life of steel and iron structures by protecting them from corrosion and in the process saves raw materials, energy and water which would otherwise be required for replacing the corroded structures. Lead is mostly used for manufacturing of lead acid batteries; lead sheets are used in building industry for roofing and cladding. Silver is used in silverware and jewellery making, while its anti-microbial as well as non-toxic properties make it useful in medicine and several consumer products.
Our processes are designed to check and ensure that the environment remains undisturbed during all stages of operation; be it reducing the dust and suspended particles which cause air pollution, to setting up zero discharge plants that do not contaminate water sources, and transitioning from open pit to underground mining.
We have embedded sustainability in all stages of mining and smelting - right from exploration, design and planning to construction, production, closure and reclamation. Planning for project closure begins even before we start, and we restore the land for productive post-operation land uses after closure.
Vision 2020
To be an industry leader in using green technologies for reducing our environmental footprint; this we envisage to achieve by innovating processes for water stewardship; introducing captive usage of energy from renewable sources; and adopting new methods for waste reduction.
Aspect Boundaries
Mining and smelting operations are hazardous to the environment by nature. Unless the associated risks are managed properly, it can have a negative impact on the communities surrounding our operations.
