In 2025, Sumitomo Chemical generated a total of 448,218metric tonnes of waste.a
Of this amount, 62.68% of Sumitomo Chemical's total waste generated was recovered through methods such as recycling, reuse, or composting, while 37.32% was disposed of through landfilling, incineration, or combustion.a
In 2025, Sumitomo Chemical reported a total waste generation of 448,218 metric tonnes, of which 62.68% was recovered through recycling, reuse, or composting.This moderate level of recovery indicates that Sumitomo Chemical is taking steps toward improving its waste diversion practices, though there is still room to enhance recycling and recovery efforts.a
Since 2020, Sumitomo Chemical's total waste generation increased by 13.26%, including a 4.73%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, Sumitomo Chemical's waste recovery rate remained relatively flat, but increased by 16.23% in 2025, hinting at early momentum toward stronger circularity practices or more robust waste treatment reporting.a
Overall, Sumitomo Chemical’s waste generation and recovery data show a mixed and inconsistent trend. A deeper analysis of the company's activities, industry benchmarks, and operational changes is needed to assess its sustainability performance more precisely.
In 2025, Sumitomo Chemical generated a total of 448,218 metric tonnes of waste.a
Of this amount, 27.05% of Sumitomo Chemical'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.54.58% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.The remaining 18.37% was either treated using unspecified methods or not clearly categorized.a
Since 2020, Sumitomo Chemical's total waste generation increased by 13.26%, including a 4.73% 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
Overall, Sumitomo Chemical'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, Sumitomo Chemical reported that 121,265 metric tonnes of its total waste output were classified as hazardous. This represents 27.05% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.Approximately 45.22% was managed through recovery methods, indicating a moderate integration of circular practices into its hazardous waste management. However, a significant share was still directed toward disposal, highlighting room for improvement in reducing the long-term impact of hazardous materials.a
