In 2025, Ajinomoto generated a total of 1,842,290metric tonnes of waste.a
Of this amount, 98.96% of Ajinomoto's total waste generated was recovered through methods such as recycling, reuse, or composting, while 1.04% was disposed of through landfilling, incineration, or combustion.a
In 2025, Ajinomoto reported a total waste generation of 1,842,290 metric tonnes, of which 98.96% was recovered through recycling, reuse, or composting.This high recovery rate suggests that Ajinomoto has implemented strong circular economy practices and actively prioritizes sustainable waste management.a
Since 2021, Ajinomoto's total waste generation remained relatively flat, but increased by 7.85% in 2025, potentially signaling a short-term operational expansion or reduced focus on waste prevention.a
Over the same period, Ajinomoto's waste recovery rate remained stable both in the long term and in 2025, suggesting limited progress, or consistent recovery performance, without major shifts in strategy.a
Overall, Ajinomoto’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, Ajinomoto generated a total of 1,842,290 metric tonnes of waste.a
Of this amount, 7.41% of Ajinomoto'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.92.59% was identified as non-hazardous waste, generally considered less harmful and subject to lighter regulatory controls.a
Since 2021, Ajinomoto's total waste generation remained relatively stable, but increased by 7.85% in 2025, potentially indicating a short-term uptick in output or weakened controls over material efficiency.a
Over the same period, the share of hazardous waste in Ajinomoto's total output increased by 61.46%, including a further 40.41% rise in 2025, suggesting a troubling upward shift toward more environmentally harmful waste streams that could raise compliance costs and environmental risks.a
Overall, Ajinomoto'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, Ajinomoto reported that 136,446 metric tonnes of its total waste output were classified as hazardous. This represents 7.41% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (99.29%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Ajinomoto has established processes to reduce the environmental burden of its most harmful waste streams.a
