In 2023, Rohm generated a total of 14,606metric tonnes of waste.a
Of this amount, 98.6% of Rohm's total waste generated was recovered through methods such as recycling, reuse, or composting, while 1.4% was disposed of through landfilling, incineration, or combustion.a
In 2023, Rohm reported a total waste generation of 14,606 metric tonnes, of which 98.6% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Rohm has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2019, Rohm's total waste generation increased by 3.77%, but declined by 12.64% 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, Rohm's waste recovery rate increased by 2.77%, while holding steady in 2023, suggesting past gains in recovery performance have stabilized.a
Overall, Rohm’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 2023, Rohm generated a total of 14,606 metric tonnes of waste.a
Of this amount, 26.22% of Rohm'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.73.78% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2019, Rohm's total waste generation rose by 3.77%, but dropped by 12.64% in 2023, indicating a possible turning point driven by improved waste-reduction practices or production slowdowns.a
Over the same period, Rohm saw a long-term increase of 16.15% in hazardous waste share, but a 1.43% reduction in 2023, indicating a recent improvement that may reflect updated production inputs, enhanced treatment, or stricter controls.a
Overall, Rohm'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 2023, Rohm reported that 3,829 metric tonnes of its total waste output were classified as hazardous. This represents 26.22% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (99.97%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Rohm has established processes to reduce the environmental burden of its most harmful waste streams.a
