Project NAUTILUS, 2028, Switzerland

Commercial Plant · 2028

The project in Switzerland represents Planeteers’ next commercial deployment at a wastewater treatment plant, applying our approach under Swiss regulatory conditions.

Developed in collaboration with our Swiss partner and investor Energie 360°, the project is designed as a commercial installation to advance deployment readiness beyond Germany. 

The project demonstrates Planeteers’ ability to deploy and further develop its technology across different regulatory contexts while maintaining a consistent operational and scientific foundation.
