AAT is not only well-known for its state-of-the-art biogas plants, but also for successful operation of these during their entire lifespan. More than 1000 biogas plants built and operating in more than 30 countries verify AAT’s success; the result of 30 years of experience and on-going in-house research and developed by highly motivated staff.
