TRANSFORMING TRANSFORMING TRANSFORMING SUSTAINABILITY REPORT FY 2023 COMMUNITIES THE PLANET THE WORKPLACE Management of Non-Hazardous Waste High Volume Low Toxicity Waste Non-hazardous waste covers general waste like paper, plastic, wood, Our operations generate High Volume Low Toxicity Waste (HVLT) like fly ash, bottom ash, red mud (aluminium refinery scrap metals and food waste. Given our commitment towards zero waste waste), jarosite (from zinc smelting), slag, lime grit (process residues from smelters and aluminium refineries), and to landfill, we aim to utilize all non-hazardous waste. phosphogypsum (phosphoric acid plant). TSPL follows a strict ‘No Single-Use Plastic’ policy and has received Single High-Volume-Low-Toxicity Waste Use Plastic Free certification from the Confederation of Indian Industry (CII). FY 2021 FY 2022 FY 2023 As a part of the certification process, verification is done by CII, under the Generated Recycled/ % Generated Recycled/ % Generated Recycled/ % provisions of the Plastics-use Protocol: Verification and Certification (Million MT) Reused Recycled (Million MT) Reused Recycled (Million MT) Reused Recycled (1.0). Cairn has received a similar certification from CII.
