Life cycle assessment studies to evaluate the sustainability of various facemasks used during COVID-19: A UAE case study
|||||

This paper evaluates the environmental impacts of various facemasks available in the UAE market through a Life Cycle Assessment (LCA) study. SimaPro software was used to conduct a cradle-to-grave LCA with a functional unit of “the number of face masks required by a person in the UAE over a month (30 days).”. Long-distance transportation was found to be a major hotspot for global warming potential. N95 facemasks were found to have the highest impacts in all categories, with cloth masks having the lowest. Other hotspots identified include polypropylene material in filtration layers, aluminium in nosepieces, electricity usage in cloth masks, and disposal scenarios. Multiple supply chain optimisations were suggested, such as the substitution of recycled aluminium in nose pieces, the use of sustainable transportation, and limiting the use of packaging material to the bare minimum to improve the sustainability of the face mask industry.
