Novel chemical free wood pulp cellulose production - Innovation @ E2Expo
Updated : December 2020
Traditional cellulose fibre production involves chemical treatment using harmful solvents which pose a problem to the environment and workers.
Spinnova, a Finland based firm has developed an innovative technology to convert wood pulp into textiles without the use of chemicals. The new technology uses a mechanical process to convert wood pulp into microfibrillated cellulose which is then converted to textile fibres.
The technology requires only 1% water as the cellulose is sourced from trees which do not need irrigation, thus having an advantage over cotton. Chemical free process has a positive environmental and social impact. Once used, Spinnova’s waste textile materials can easily be upcycled into new textiles rather than the traditional process of making insulation materials. The company also plans to use other agricultural waste sources in future.
The company has won the Fast Company’s 2019 World Changing Ideas Award in the experimental category for creating fibre from cellulose.
