Cheap electricity thanks to green energy from wastewater

FlexBio Technologie GmbH is an innovative environmental technology company with its unprecedented anaerobic biological wastewater treatment plants. We create resource-saving and lasting solutions in the fields of biogas technology and wastewater treatment. We have thus developed a system for the sustainable use of water, one of the most valuable resources on our planet. With our innovative process, we are committed to harnessing potential. This includes, in particular, energy from wastewater. Because: Our wastewater treatment plants enable energy to be recovered from wastewater and also ensure a reduction in the cost of wastewater disposal. Both pre-treatment to avoid heavy pollution charges and full clarification for direct discharge can be realized with the standardized process. The FlexBio plants to generate energy from wastewater are offered in compact and modular container solutions. With these anaerobic wastewater treatment plants, we are already a small step closer to our vision of a sustainable future.

That makes us innovative


The anaerobic wastewater treatment in compact container design is the first and only of its kind. It enables effective and efficient wastewater treatment in just a few process steps. In addition, our plants ensure a permanently positive energy balance.


We generate energy from your wastewater. The CO2 savings associated with our wastewater treatment plants avoid negative environmental impacts. Hardly or very little sewage sludge is produced. These aspects enable sustainable business development and create an additional source of revenue.


Due to the unprecedented container design of our anaerobic biological wastewater treatment plants, it is possible to transport our systems comfortably, to install them quickly and easily (Plug&Play) and to equip them with further modules (modular principle). You don’t have to invest in the final expansion stage today. You invest as needed.


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