Competent and customer-orientated support in all phases of your sewage sludge disposal project

sludge2energy GmbH

Our vision:

Thinking the sewage treatment plant through to the end.

In every sewage treatment plant, sewage sludge is produced as a by-product during wastewater treatment and needs to be disposed of. Through the thermal utilisation of sewage sludge, our plants make an important contribution to environmental protection and disposal safety. This guiding principle led to the development of the "sludge2energy process" and the founding of sludge2energy GmbH.

Our Mission:

We deliver competent and customer-oriented support in all phases of your sewage sludge utilisation project.
