In 2025, ATS generated a total of 4,209 metric tonnes of waste.a
Of this amount, 10.79% of ATS'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.89.21% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2023, ATS's total waste generation decreased by 39.85%, with an additional 4.97% decline in 2025, suggesting a consistent and deliberate effort to minimize waste generation at the source.a
Over the same period, ATS saw a long-term increase of 90.59% in hazardous waste share, but a 4.64% reduction in 2025, indicating a recent improvement that may reflect updated production inputs, enhanced treatment, or stricter controls.a
Overall, while ATS is generating less waste and has made recent gains in reducing hazardousness, the long-term increase in harmful materials still casts doubt on the sustainability of its waste stream.a
