With increasing environmental concerns associated with the production of fibres from cotton and other plant based sources, Nanollose, an innovative Australian company, has developed what it believes is a revolutionary plant-free viscose-rayon fibre product. With its new development, the company aims to offer sustainable alternative to plant-based fibres such as viscose-rayon, which are commonly used but which the company says have significant environmental impacts. Viscose-rayon is a wellestablished fibre made from cellulose predominantly derived from woodpulp, and used to make everything from home furnishings to clothing. However, there might be significant environmental concerns surrounding its production, as a considerable number of trees are cut down, chipped and then treated with chemicals, followed by energy intensive purification process to source the cellulose required for rayon production, Nanollose says.
