In 2025, Methanex generated a total of 5,582metric tonnes of waste.a
Of this amount, 28.81% of Methanex's total waste generated was recovered through methods such as recycling, reuse, or composting, while 71.19% was disposed of through landfilling, incineration, or combustion.a
In 2025, Methanex reported a total waste generation of 5,582 metric tonnes, of which 28.81% was recovered through recycling, reuse, or composting.This moderate level of recovery indicates that Methanex is taking steps toward improving its waste diversion practices, though there is still room to enhance recycling and recovery efforts.a
Since 2021, Methanex's total waste generation increased by 56.67%, including a 15.79%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, Methanex's waste recovery rate increased by 31.42%, while holding steady in 2025, suggesting past gains in recovery performance have stabilized.a
Overall, Methanex’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, Methanex generated a total of 5,582 metric tonnes of waste.a

Since 2021, Methanex's total waste generation increased by 56.67%, including a 15.79% 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, the share of hazardous waste decreased by 18.03%, yet rose by 133.45% in 2025, potentially signaling operational variability, temporary setbacks, or less effective hazardous waste mitigation in the short term.a
Overall, Methanex'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, Methanex reported that 1,265 metric tonnes of its total waste output were classified as hazardous. This represents 22.66% of its overall waste generation.a
The company treated this hazardous waste using a combination of methods.A majority (75.34%) was diverted from disposal through recovery-oriented treatments such as recycling or reuse. This suggests that Methanex has established processes to reduce the environmental burden of its most harmful waste streams.a
