VTT turns discarded textiles into cellulosic man-made fibers 



70,000 tonnes of textiles is thrown away in Finland each year, and most of it is currently burned to energy. Around one third of the discarded textiles are made of cotton. Hence there is a huge and underutilized source of cellulosic raw material in Finland only. VTT coordinates a project called The Relooping Fashion Initiative that aims at modelling and demonstrating how closed-loop recycling of discarded textiles into new material can be done. The partners of the project; Ethica, Suez, Helsinki Metropolitan Area Reuse Centre, Seppälä, Pure Waste Textiles and Original Repack, represent the whole closed-loop value chain, and participate in a unique pilot production experiment in Valkeakoski, Finland.....
