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.

Highlights and sustainability benefits

When compared to one kilogram of petrochemical dye, one kilogram of Pili dye saves 100kg of crude oil and 10kg of toxic chemicals.

Recognition

 BPI France contributed €1.6 million ($1.9M) via the Global Innovation Challenge in 2018 to support the development of Pili's dyes

About the Work

Once an effective enzyme cascade is designed, large-scale production can begin. They produce their dyes by integrating the genes for each enzyme into bacteria or other microorganisms, our cell factories. These bacteria are grown in water-based bioreactors, using sugar as their main food source. This process requires no fossil fuels and no toxic inputs, and produces no harmful byproducts, making their bacterial biofactories both highly efficient and non-polluting. The company is currently developing its initial product line and refining the process to work at industrial scale.

About the Innovator

Founded in 2015 in Paris at La Paillasse, PILI is a Rebel Bio alumni (SOSV) and a member of the Toulouse White Biotechnology (TWB) consortium. Now located in France at Le Cnam (Paris) and TWB (Toulouse), Pili is the world’s leading company in the production of biotech dyes and pigments using proprietary fermentation technology. The company is co-founded by Jérémie Blache, Guillaume Boissonnat, Marie-Sarah Adenis, and Thomas Landrain.
