In 2025, SK Hynix generated a total of 615,779metric tonnes of waste.a
Of this amount, 99.85% of SK Hynix's total waste generated was recovered through methods such as recycling, reuse, or composting, while 0.15% was disposed of through landfilling, incineration, or combustion.a
In 2025, SK Hynix reported a total waste generation of 615,779 metric tonnes, of which 99.85% was recovered through recycling, reuse, or composting.This high recovery rate suggests that SK Hynix has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2022, SK Hynix's total waste generation increased by 4.31%, including a 8.18%increase in 2025, indicating a persistent upward trend that may reflect scaling operations, inefficiencies in resource use, or a lack of effective waste minimization practices.a
Over the same period, SK Hynix's waste recovery rate remained stable both in the long term and in 2025, suggesting limited progress, or consistent recovery performance, without major shifts in strategy.a
Overall, SK Hynix's waste generation is rising, yet its recovery rates have remained stagnant. This suggests that the company’s operational growth is not being matched by parallel improvements in its waste treatment practices, potentially increasing its environmental footprint.
In 2025, SK Hynix generated a total of 615,779 metric tonnes of waste.a
Of this amount, 64.46% of SK Hynix'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.35.54% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2022, SK Hynix's total waste generation increased by 4.31%, including a 8.18% rise in 2025, reflecting a persistent upward trend that could be linked to operational growth, inefficient material use, or limited investment in waste prevention systems.a
Over the same period, SK Hynix reduced the hazardousness of its waste by 5.98%, with a further 1.11% decline in 2025, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.a
Overall, SK Hynix is generating more waste but has significantly reduced the share of hazardous materials, suggesting a partial decoupling of volume and toxicity that could reflect more responsible inputs or enhanced treatment.a
In 2025, SK Hynix reported that 396,916 metric tonnes of its total waste output were classified as hazardous. This represents 64.46% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (99.77%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that SK Hynix has established processes to reduce the environmental burden of its most harmful waste streams.a
