Our Technology relies on

powerfull color cell factories






How it works

We build powerfull enzymes to transform sugar into colors

The core of our technology is based on enzymes.

Enzymes are very powerful proteins that catalyzes most biological reactions. All living beings have enzymes.

Enzymatic synthesis is particularly interesting for biomaterial production in a sustainable way for it has a remarkable energy efficiency, and high specificity in the production of molecules.

At PILI we develop a proprietary technology based on the design of enzymatic cascades to obtain dyes from renewable carbon sources (sugar and other nutrients).

Thanks to the specificity and efficiency of the enzymes, we develop tailored colors adapted to various applications

We use microorganisms as a biofactory to scale 

To replicate this process on a large scale, we integrate those enzymes in microorganisms such as bacteria.

Bacteria grow in water, use sugar as a renewable raw material and do not generate any polluting byproduct (they do not need any fossil ressources, no toxic chemicals, and need low T°C)

Bacteria are very powerful « biofactories » as they have a very high efficiency without polluting.

We grow them with renewable nutrients


This biological process is not only efficient and sustainable, it is also scalable!

Microorganisms replicate the tools very efficiently as they reproduce. And they reproduce very fast : nearly every 20 minutes! At the end of a day, we have billions of microorganisms, each of them producing pigments!

We produce the pigments in large quantities through fermentation

We grow bacteria thanks to fermentation processes.

Just like beer, in big fermentors but instead of brewing beer, we brew renewable colors!

The processes we use are very well-known in big scale productions of other compounds such as insuline in the pharmaceutical industry. We thus know that our technology can be brought up to high scale with low costs and accurate production.

At the end of this process, we separate bacteria from the pigments by filtering them (the size of a bacteria is 1000 times bigger than the targeted molecules so that's very easy.

After filtration, we formulate the dyes for various applications


Among all the applications,

we focus on textile as this industry requires the largest volumes of color.

Here lies the main sustainability challenge.


Finally, we deliver dyes to our clients!



We are currently developping our products with our clients by testing the dyes in differents applications based on their technical specifications.
