In 2025, Bangkok Expressway and Metro generated a total of 1,158metric tonnes of waste.a
Of this amount, 10% of Bangkok Expressway and Metro's total waste generated was recovered through methods such as recycling, reuse, or composting, while 90% was disposed of through landfilling, incineration, or combustion.a
In 2025, Bangkok Expressway and Metro reported a total waste generation of 1,158 metric tonnes, of which 10% was recovered through recycling, reuse, or composting.This low recovery rate highlights limited waste diversion and suggests that Bangkok Expressway and Metro may be relying more heavily on landfill or incineration, underscoring opportunities for stronger resource recovery initiatives.a
Since 2023, Bangkok Expressway and Metro's total waste generation increased by 38.9%, including a 8.79%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, Bangkok Expressway and Metro's waste recovery rate increased by 87.89%, including a 227.68% rise in 2025, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, Bangkok Expressway and Metro has seen a consistent rise in waste generation both over the long term and in the year 2025. However, the company has also steadily improved its waste recovery performance, suggesting that it is actively working to offset the environmental consequences of increased production through enhanced circularity efforts.
In 2025, Bangkok Expressway and Metro generated a total of 1,158 metric tonnes of waste.a
Of this amount, 8.51% of Bangkok Expressway and Metro'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.91.49% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2023, Bangkok Expressway and Metro's total waste generation increased by 38.9%, including a 8.79% 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, Bangkok Expressway and Metro reduced the hazardousness of its waste by 5.47%, with a further 6.15% decline in 2025, suggesting a sustained and meaningful shift toward safer waste profiles and lower environmental impact.a
Overall, Bangkok Expressway and Metro 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, Bangkok Expressway and Metro reported that 98 metric tonnes of its total waste output were classified as hazardous. This represents 8.51% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (69.62%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Bangkok Expressway and Metro has established processes to reduce the environmental burden of its most harmful waste streams.a
