In 2025, SK Chemicals generated a total of 32,034metric tonnes of waste.a
Of this amount, 80.85% of SK Chemicals's total waste generated was recovered through methods such as recycling, reuse, or composting, while 12.9% was disposed of through landfilling, incineration, or combustion.The remaining 6.25% was either treated using unspecified methods or not clearly categorized.a
In 2025, SK Chemicals reported a total waste generation of 32,034 metric tonnes, of which 80.85% was recovered through recycling, reuse, or composting.This high recovery rate suggests that SK Chemicals has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2023, SK Chemicals's total waste generation decreased by 7%, including a further 15.42% drop in 2025, highlighting a consistent and deliberate reduction in waste production over time.a
Over the same period, SK Chemicals's waste recovery rate declined by 6.06%, with a further 7.27% drop in 2025, underscoring a weakening in waste diversion performance and a potential drift away from circular waste strategies.a
Overall, while SK Chemicals has successfully reduced its total waste generation, its waste recovery efforts have also declined. This pattern could suggest a shift in strategy away from circular treatment methods or a lag in recovery infrastructure development.
In 2025, SK Chemicals generated a total of 32,034 metric tonnes of waste.a
Of this amount, 35.46% of SK Chemicals's total waste generated of was classified as hazardous waste, characterized by properties such as toxicity, flammability, corrosiveness, or reactivity that may pose risks to human health, ecosystems, or the environment.64.54% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2023, SK Chemicals's total waste generation decreased by 7%, with an additional 15.42% decline in 2025, suggesting a consistent and deliberate effort to minimize waste generation at the source.a
Over the same period, the share of hazardous waste in SK Chemicals's total output increased by 22.63%, including a further 28.07% rise in 2025, suggesting a troubling upward shift toward more environmentally harmful waste streams that could raise compliance costs and environmental risks.a
Overall, SK Chemicals's waste and hazardousness trends are mixed or inconclusive. A more detailed review of its materials, industry standards, and operational changes would help clarify the net environmental impact of its waste strategy.a
In 2025, SK Chemicals reported that 11,358 metric tonnes of its total waste output were classified as hazardous. This represents 35.46% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (60.87%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that SK Chemicals has established processes to reduce the environmental burden of its most harmful waste streams.a
