Sustainability

Water pollution is a major environmental concern today that adversely affects the surroundings, causing serious injury to environment as well as human health. At JSPL, water pollution is controlled by following a range of stringent regulatory measures and monitoring processes. The company has attained ‘Zero Discharge’ status by adopting state-of-the-art technology for water treatment. As per the guidelines of CREP, a 4.3 – 4.9 m³ per T of long product is currently being used by JSPL.

Some of the measures, which have been implemented for effective control of water pollution, are as follows:   

• Coke Oven Quenching: The wastewater generated during quenching is taken to settling tanks. After settling, the water is reused for quenching.
• Sinter plant: Blow-down water is used in sinter nodulizing.
• Blast furnace: Dust laden wastewater is treated in effluent treatment plants and treated water is recycled back to the process.
• SMS: The wastewater is taken to a settling tank and outlet water of the tank is reused. The blow-down water is used in slag granulation.
• Rolling mill: Process wastewater is skimmed for oil and scale and then recycled back to the plant. No wastewater is discharged. 
• DRI: Cooling close-circuit effluent-recycling system has been installed. Wastewater from cooling section is taken to hot water well, from where it is taken to the cooling tower and then to the cold water well, from where it is recycled back to process.
• Power Plant: DM plant wastewater is treated in neutralization pit. After treatment, the water is reused for wet ash handling system.
• Submerged Arc Furnace: Wastewater is reused for slag cooling and dust suppression.
• Sewage Treatment Plants - Three sewage treatment plants have been installed. The treated water is reused in greenery development.
• Garage, DG Set & Compressor Houses: Oil separators have been provided. Clean water is further treated in STP.
