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).
