Business Profile

Reliable solutions for commercial success and a sustainable future.


Our components are known for their outstanding operational reliability, availability and high-quality workmanship. We set technological standards that stand out on the practical level with exceptional efficiency standards. And all this at a price in line with the market.

Our core business is dry digester technology and landfill gas technology. Municipal solid waste (MSW) is converted into energy by separating inert materials and treating the organic fraction by anaerobic digestion. Produced biogas and landfill gas can be used for electricity and heat generation or is upgraded to biomethane which is a substitute for fossil natural gas.

We have built and operated dry fermentation plants successfully for more than 10 years, processing approximately 10.000 tons per day of mixed collected municipal solid waste.

The combination of large-scale waste treatment and biogas production as a renewable energy source makes our mission sustainable. AAT&ANKA is committed to a cleaner planet with experience, know-how and technology.
