Surat/Hazira (Gujarat) [India]: ArcelorMittal Nippon Steel India (AM/NS India) has announced an investment of Rs 273 crore for zero liquid discharge and other environmental initiatives at its Hazira steel complex.
According to AM/NS India, the Zero Liquid Discharge system will cover the entire Hazira plant and help AM/NS India in eliminating liquid waste by enabling the reuse of the entire treated effluent with RO units. The zero liquid discharge system is being set up at the cost of Rs. 77 crore. The total length of the network is 14 km. The contracts related to civil works and other contracts have already been awarded, and the system is expected to be completed by March 2023.
The plants covered in the first phase include Steel Making Plants 1 and 2, Hot Strip Mill, CRM-DSC, ASU, DRI-5-6, COREX 1-2, Plate mill, and INOX cryogenic Air Separation Unit (ASU).
“AMNS is committed to the best environmental norms and adopting green practices at our Hazira plant. We have undertaken various environmental improvement-related projects which are in line with the global steel manufacturing standards,” said Santosh Mundhada, Executive Director at AM/NS India.
AM/NS India has also finalised an Environment Improvement Roadmap plan that will entail an expenditure of Rs. 173 crore in the initial phase. This includes measures to reduce the ambient dust level by installing various air pollution control measures in the plants, besides road strengthening, deployment of more sweeping machines on the material handling roads, etc.
AM/NS India is also expanding the green belt within the Hazira plant complex by planting 3.60 lakh trees this year at a cost of Rs.12 crore.
“The plant’s greenbelt area will cross 33% when the tree plantation campaign is completed by December. The increased greenbelt will also help in controlling the ambient dust level,” said Mr. Mundhada.
To mitigate sulphur emissions, AM/NS India is looking to make maximum use of natural gas and use coal with low sulphur content.
AM/NS India has announced plans to increase its steelmaking capacity at Hazira from 9 million tonnes per annum to 18 million tonnes with an investment of Rs. 45,000 crores.
