Introduction: Given the current industrial development, the footprint of chemical production’s environmental toxicity is increasing. The toxicity footprint depends on the environmental conditions and the time of poisoning agents’ entry into the environment, as well as the properties of the substance released in terrestrial and aquatic (fresh and salty) ecosystems. In environmental management, a comprehensive understanding of the toxicity footprint and its causes is of paramount importance. Using life-cycle assessment, the toxicity footprint may be studied comprehensively and integratedly and based on the life cycle perspective, resulting in the identification of the most important life cycle components and stages affecting it. The present study was aimed at investigating the toxicity footprint of methanol production severally by utility and process units in terrestrial and aquatic ecosystems by the life-cycle assessment method. Identification and quantification of the toxicity footprint severally by process and utility units would contribute to better recognizing the methanol production unit’s situation. By determining the necessary priorities, the plan of reducing the footprint of the product could be initiated. The system boundary was gate to gate of methanol production from natural gas.
Materials & Methods: The functional unit in this study was one thousand tons of methanol production.
Results: According to the current study results, compared to the utility units, the process units were more effective in the toxicity footprint of terrestrial ecosystems, freshwater, and seawater.
Conclusion: The rate of toxicity footprint associated with process units in terrestrial ecosystems, fresh water, and seawater was 96.3%, 77.3%, and 76.4%, respectively.
