Fresh air ventilation system is integrated with active cooling system to improve indoor air quality, which would enhance occupant comfort. One-site renewable energy of 100 kWp is installed that would generate 1,62,000 units every year. Online energy monitoring system is installed to track the energy performance of the project and would help in identifying energy use by various building component such as lighting, UPS, air-conditioning, exterior lighting usages, etc. water meters are installed at several places to record water usages.
HZL and IGBC would work together to further enhancing the building performance and would play greater role in green building movement led by IGBC.
Hindustan Zinc has developed a lush green belt across its corporate office and residential colony. Hindustan Zinc has already installed solar roof top projects. The Yashad Bhawan, head office of Hindustan Zinc too runs on Solar Power. The Company is also looking to develop solar energy projects in other parts in the State of Rajasthan. Hindustan Zinc has been working progressively towards setting up 115 MW of solar energy projects with an investment of Rs. 630 crores. Hindustan Zinc also has over 1.3 million green plantations across its business locations.
The Company’s mining and smelting operations are based on environment friendly technologies that led the plant to conserve water and energy. The operations are working on zero discharge principle and the Company is putting all efforts and research for gainful utilization of waste generated at its mines, smelters and power plants.
Hindustan Zinc has installed Adiabatic Cooling Towers (ACTs), air cooled heat exchangers for minimizing loss of water through evaporation. ACT installation has resulted in overall reduction in usage of water.
The Company has also installed Effluent Treatment Plant (ETP) for treating the ‘effluents’ generated by different processes at smelters. The ETP with reverse osmosis plants installed at all smelting locations is resulting in reducing freshwater foot prints of the Company. The treated effluents are recycled in the process ensuring ‘Zero Discharge’.
Hindustan Zinc has commissioned Udaipur’s first Sewage Treatment Plant (STP), with a capacity to treat 20 MLD of sewage, under the public-private-partnership model. This STP has effectively addressed the growing problem of pollution in Udaipur city’s water bodies and contributed towards enhancing the overall aquatic life and aesthetic look of lakes. Hindustan Zinc is now considering enhancing the capacity of current STP from 20 MLD to 40 MLD.
The Company also has green wind energy farms with 274 MW of power generation capacity located in Gujarat, Karnataka, Rajasthan, Tamil Nadu and Maharashtra.
