with resource-saving and sustainable solutions in the field of wastewater and biogas technology.

Shaping the future together sustainably – customers and partners who trust us:

That makes us innovative


Anaerobic wastewater treatment is the first and only of its kind in a compact container design. This enables the effective and efficient removal of impurities in the wastewater in just a few process steps, as well as a permanently positive energy balance.


We generate energy from your wastewater. The associated savings in CO 2 also avoids negative environmental influences. Hardly or very little sewage sludge is produced. All of these aspects enable sustainable corporate development and create an additional source of income.


Thanks to the unique container design of our wastewater treatment systems, it is possible to transport our wastewater treatment systems easily, to install them quickly and easily (plug & play) and to equip them with additional modules (modular principle). You don’t have to invest in the final expansion stage today. You invest as needed.


Less sewage sludge – more energy: With the anaerobic wastewater technology we use, the organic matter in the wastewater is converted into methane-rich gas (approx. 90 – 95%) by microorganisms.

Delivered systems

Sewage treatment plants

We manufacture and market a specially developed process for anaerobic wastewater treatment in a compact and modular design. The FlexBio compact systems can be transported quickly and easily. The systems are pre-assembled in our factory and delivered after a test phase. The design enables a space-saving installation according to the plug & play principle, so that the connection of the compact systems is possible on most companies.
