Renewable textile dyes using enzymes and microorganisms - Innovation @ E2Expo
Updated : December 2020
Microbial fermentation for renewable dyes
Pili uses enzymes and microorganisms to transform sugar into vibrant, fully renewable pigments for textiles through natural processes. Pili aims to replace chemical processes with microbial fermentation. Fermentation allows micro-organisms to break down renewable plant-based matter like sugar or wood, to reshape it into dyes. This process has a reduced energy balance since the enzymes in these microorganisms work at room temperature, without toxic solvents, and using far less water and energy than petrochemical processes. It uses five times less water and works at room temperature, where industrial dyes often reach over 300°C.

When compared to one kilogram of petrochemical dye, one kilogram of Pili dye saves 100kg of crude oil and 10kg of toxic chemicals.
BPI France contributed €1.6 million ($1.9M) via the Global Innovation Challenge in 2018 to support the development of Pili's dyes
