WASTE & EFFLUENT MANAGEMENT

Thrust Areas: For Judicious Waste Management

• Dedicated storage for category-wise waste in scrap yard across all plants
• Systematic tracking of the quantity of waste generated and waste disposed
• Ensure proper waste disposal – diverting waste away from landfill
• Imbibing the principle of 3R – Reduce, Reuse and Recycle
• Sensitisation of employees on waste handling methods

Waste Generated

In FY 2021-22, our organisation-wide total waste generation was 12,579 MT, of which 827 MT was hazardous waste, 21 MT was E-waste, 0.09 MT was bio-medical waste while the rest was non-hazardous waste.

Our organisation-wide Specific Hazardous Waste Generation (SHWG) was 2.31 Kg/KL of FG while our Specific Hazardous Waste Generation for our manufacturing facilities accounted to 2.30 Kg/KL of FG

Hazardous waste generated due to our operations mainly includes distillation residue, Effluent Treatment Plant (ETP) sludge, paint sludge, dirty resin, contaminated barrel/tins, filter cartridge, and contaminated cotton waste.

a) Manufacturing Facilities - Specific Hazardous Waste Generation is ratio of hazardous waste generated in Plants to Production of Finished Goods during specified period.
b) Organisation-wide - Specific Hazardous Waste Generation is ratio of hazardous waste generated in Plants and R&D centre to Production of Finished Goods during specified period.

Waste Disposal

At KNPL, the waste generated is segregated and then disposed as per statutory requirement and applicable norms to authorised Treatment, Storage and Disposal Facilities (TSDFs), who then dispose, reuse or recycle it as applicable. We have been successful in diverting most of our hazardous waste away from landfill through adoption of co-processing of hazardous waste to cement kilns.

Waste Diverted From Disposal

• Reusable cartridge in the filtration process
• Cleaning solvents of all major resins are reused in the next batch of same resins
• In paint section, system controls have been implemented to ensure reuse of paint filled in part filled cans in the next compatible batch of paint
• In operations, cleaning solvent is reused after distillation process again for equipment cleaning
• Paint Pigging wash water reuse
• TiO2 recovery through de-dusting
• Reusing drums and barrels
• Take-back mechanism with suppliers supplying raw materials in plastic bags

Waste Directed to Disposal

• Barrels/Tins are recycled through authorised vendors
• Plastic waste, corrugated boxes and metal scrap generated within factory premises is recycled through authorised vendors
• Raw materials procured in recyclable packaging material
• E-waste sent through buy-back programme

Plastic Waste Management

At KNPL, we have taken concerted efforts to reduce our plastic waste generation through our manufacturing facilities. Through rigorous due-diligence process and constant communication, we encourage suppliers to substitute plastic with alternate materials or implement a take back mechanism. During the reporting period, we ensured zero procurement and usage of packing material less than the thickness limit in microns set by the regulatory bodies.

Extended Producer Responsibility

We, at KNPL, have initiated our efforts to meet the targets laid under EPR and tackle the challenge of eliminating plastic waste from the ecosystem to the maximum extent. We are currently in the process of our registering ourselves on the newly launched centralised e-portal by Central Pollution Control Board (CPCB). We have also associated with external agency to ensure diligent collection, treatment and disposal of postconsumer plastic waste in line with the EPR target and maximum traceability.
