About

NXSTEP is a new generation of wastewater treatment plant. It relies on the microalgae-bacterial symbiosis to offer intensive wastewater treatment. Using photobioreactors, this biotechnology was the subject of two demonstrators in 2018 and 2023 to meet the challenge of operating at positive energy and negative carbon with a view to reusing wastewater.

This program is the result of multi-partner work (CNRS/INRAE).
