Industrial wastewater treatment solution inspired by nature: microalgae

Circularity, the backbone of the process

ZENI is an impact-driven company that offers a solution inspired by nature, microalgae, for sustainable and circular water management in industries.

Our solution is based on the ability of microalgae to purify water (treat nitrates, phosphates and other pollutants).

It allows wastewater to be reclaimed by producing:
treated water that can be reused
microalgae suitable for valorization.
It supports manufacturers in their environmental transition.

“Our biomimetic solution provides a dual ecological and economic benefit, through the production of reusable treated water and valorizable biomasses.”
Jean-Michel Pommet

The benefits of our solution

Zeni reclaims wastewater, making it possible to preservve natural resources and produce high-value-added algal biomass for agriculture and animal feed.
