In 2023, ONEOK generated a total of 39,909metric tonnes of waste.a
Of this amount, 1.9% of ONEOK's total waste generated was recovered through methods such as recycling, reuse, or composting, while 98.1% was disposed of through landfilling, incineration, or combustion.a
In 2023, ONEOK reported a total waste generation of 39,909 metric tonnes, of which 1.9% was recovered through recycling, reuse, or composting.This low recovery rate highlights limited waste diversion and suggests that ONEOK may be relying more heavily on landfill or incineration, underscoring opportunities for stronger resource recovery initiatives.a
Since 2019, ONEOK's total waste generation increased by 36.55%, but declined by 41.45% in the year 2023, suggesting a potential shift toward more efficient material use or the early impact of waste reduction strategies.a
Over the same period, ONEOK's waste recovery rate increased by 1.29%, including a 263.11% rise in 2023, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, while ONEOK has increased waste over the long term, recent reductions in waste generation and strong improvements in recovery indicate a strategic pivot toward better waste management and more sustainable practices.
In 2023, ONEOK generated a total of 39,909 metric tonnes of waste.a
Of this amount, 0.47% of ONEOK'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.99.53% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2019, ONEOK's total waste generation rose by 36.55%, but dropped by 41.45% in 2023, indicating a possible turning point driven by improved waste-reduction practices or production slowdowns.a
Over the same period, the share of hazardous waste in ONEOK's total output increased by 202.44%, including a further 350.14% rise in 2023, suggesting a troubling upward shift toward more environmentally harmful waste streams that could raise compliance costs and environmental risks.a
Overall, while ONEOK has recently reduced waste output, its hazardous waste share continues to rise, raising concerns about treatment efficiency or growing reliance on harmful materials despite short-term volume improvements.a
