Spotted: A French startup, PILI, is using microbial fermentation to produce sustainable textile dyes. The company’s technology offers four essential building blocks: sustainability, high-scale production, high performance and accessibility to the masses.

PILI’s approach avoids the use of fossil fuels and corrosive chemicals that have a harmful environmental impact. It uses microorganisms that are needed in the fermentation process of, which allows microorganisms to break down renewable plant-based matter that can be reshaped into dyes.

The company has raised €3.6 million to brew colours at an industrial scale. With its new funding, PILI plans to take its technology to pilot scale and to validate the performance of its dyes with industry partners. They estimate that production will reach the kilogram scale this year, with the first products being sold a year or two later, at which point production is expected to reach an industrial scale.
