Summary: Resumo This work compares the environmental impacts of cellulose nanowhiskers obtained from four tropical vegetal fibers: cotton linter, cotton plume, green coconut husk, and sugarcane bagasse. Life cycle impact assessment was performed, according to ISO 14040, considering the following impact categories: eutrophication, human toxicity, ecotoxicity, and climate change. The evaluation showed that the lowest impacts occur when cotton plume is used as the source of cellulose to the extraction of nanowhiskers.
