Waste Water

 

Today, 1 in 3 people – around 2.2 billion of total population – live without safe drinking water on one hand, while on the other hand, a large volume of water is consumed for industrial purposes, which eventually generates a high amount of wastewater. Globally, 2 million tons of sewage, industrial and agricultural waste is discharged into the world's waterways thereby polluting more freshwater. Wastewater generally contains organic and toxic chemicals and hence is unfit for consumption without proper treatment. Considering these scenarios, utilization of wastewater and in-turn reducing the freshwater intake is how JSW Group as an organization has resolved to take part in resource conservation and play an important role to fight water waste.

SDG 6: Clean Water and Sanitation

 

  • JSW Steel understands the importance of water as raw material and hence has adopted the following innovative methods of water conservation through treatment and reuse of industrial effluents and domestic sewage.
     
  • Zero Liquid Discharge 

    JSW has come up with an initiative to reduce wastewater discharge from its premises by the installation of a Zero Liquid Discharge (ZLD) facility across all its steel manufacturing locations. ZLD is an advanced water treatment process that purifies and recycles the wastewater, besides helping industries limit wastewater discharge and maintaining a sustainable environment. Key areas where wastewater is reused include slag cooling, slag granulation plant. There are a number of benefits of ZLD for JSW:
    • Lowered waste volumes decrease the cost associated with waste management.
    • Recycling water on site - lowering water acquisition costs and risk.
    • Recycling on-site can also result in fewer treatment needs, versus treatment of effluent required to meet stringent environmental discharge standards.
    • Improvement in environmental performance
 

  • Sewage Treatment Plant

    Apart from industrial effluent, JSW Steel also manages sewage through sewage treatment plants and recovers quality water through reverse osmosis which is used in horticulture. Additionally, JSW has also been able to supply recycled water for irrigation in water-starved regions around the operations.
 

 

Water Consumption & Conservation trend of JSW Steel

 

Recycling of treated waste water has helped JSW reduce specific fresh water consumption by 8.32% in FY19 compared to FY18

JSW Steel, through various well thought initiatives, has been able to increase the water recycled over the course of past three years.
