Operation Water Efficiency

At KNPL, water is used as a raw material for water-based paints, in utilities, for cleaning of process equipment, landscaping and horticulture development as well as for domestic purposes. Being a responsible organisation, we understand the importance of water management and have established water management goals for reducing water usage across all plants.

Key water conservation initiatives are:

  • Reuse of boiler condensate as boiler feed
  • Multiple effect evaporator condensate recycled in boiler feed
  • Utility RO reject reused for pallet cleaning and boiler ash quenching
  • STP treated water reused for gardening/toilet flushing
  • ETP treated water reused for utility make-up
  • Provision of filter at cooling tower area for recycling of reactor drained water
  • Stripping water recycling in tanker cleaning
  • Preventive maintenance of steam traps
  • Installation of softener plant to reduce RO rejects
  • Installation of dry screw vacuum pump in place of water based vacuum pump
  • Water losses (Drift and Evaporation) reduction by routing the water directly from inlet pump to the collection tank, thereby bypassing the cooling tower whenever the inlet water temperature goes below a defined set-point

Our Specific Water Consumption decreased by 20% since FY 2015-16. We have adopted an incremental target of reducing our SWC by 5% year-on-year till 2021, since FY 2018-19.

Water usage in KL/Tone of FG

Through the years, we have managed to gradually increase our recycled water consumption. Our recycled water consumption has increased from 10% to 22% since FY 2015-16.

All our facilities are equipped with rainwater harvesting systems. At Lote, the collected water is used in process whereas in other plants, a groundwater recharge set-up is installed.

GRI 103-1 Management approach: Explanation of the material topic and its boundary

Material aspects & scope

GRI 103-2 Management approach: The management approach and its components
GRI 103-3 Management approach: Evaluation of the management approach
GRI 306-1 Water discharge by quality and destination Effluent treatment
GRI 306-2 Waste by type and disposal method We have a dedicated storage for category-wise waste in scrapyard across all plants. The waste generated is segregated and then disposed as per statutory requirement to authorised Treatment, Storage and Disposal Facilities (TSDFs), who then dispose, reuse or recycle it as applicable.
GRI 306-3 Significant spills During the year, there were no cases of significant spillage at any of our manufacturing sites.
GRI 306-4 Transport of hazardous waste No hazardous waste transported internationally. All are disposed to local authorised TSDF. Material and waste management
GRI 306-5 Water bodies affected by water discharges and/or runoff All major facilities are zero effluent discharge; hence water bodies are not affected adversely

Keeping Our Waters Clean

Zero Liquid Discharge: Our two-way approach of Reduction at source and Reuse has enabled us to be a Zero Liquid Discharge Organisation.

Installed dedicated treatment facilities for domestic and industrial effluents across all our plants

Our industrial effluents are treated in Effluent Treatment Plant (ETP) and then passed through Reverse Osmosis (RO) and Multi Effect Evaporator (MEE)

All plants are equipped with in-house laboratory to monitor the quality of effluent to ensure compliance with Central Pollution Control Board (CPCB) and State Pollution Control Board (SPCB) norms
