About atres

For what atres stands for?

Atres stands for anaerobic technique and renewable energy systems.

Who is atres?

The company was founded by Dipl.-Ing. Gunther Pesta in 2006 as “Atres engineering biogas”. Simultaneously to the addition of the business areas analytics, research, academy, consulting and products, we abbreviated the company name into “atres”.

Atres is still owner-managed – economically and personally independent from its customers. The interdisciplinary team of atres ensures a competent treatment of the queries and professional support.

What does atres offer?

Atres offers consulting and laboratory services for energy provision out of organic residual material, regrowing raw material and high polluted wastewater through fermentation into biogas. We support our clients to solve technical, process technical and process biological issues – from planning to commissioning, to extension and efficiency increase.

Our own biogas special laboratory for chemical technical analysis and our biogas technical center with laboratory and pilot biogas plants for research and experiments, is located in Freising-Weihenstephan.
