About Us

BTA International GmbH is the leading specialist for the wet-mechanical pretreatment and digestion of all types of organic waste containing contaminants.

Thanks to highly efficient contaminant removal, BTA® Pulper and GRS produce a clean suspension for the subsequent wet digestion. At the end of the BTA® process, biogas, digestate and separated impurities can be put to further use.

Already in the early 1980s, our founders were concerned about the effects of the then common waste disposal, the devastating consequences for the environment and the waste of resources. With the conviction that environmentally friendly recycling was possible, they set out to develop the best technology for processing organic waste.

35 years and 50 successful projects later, we are still working with the same conviction and the same aspiration to develop and implement first-class technical solutions. The Bavarian company with the somewhat unwieldy name "Biotechnische Abfallverwertung GmbH & Co. KG" has in the meantime become an international player with references from Canada to Australia. A corresponding range of cultural backgrounds also characterises our team of biologists, chemists, engineers and business economists, among others.

With this experience and our comprehensive range of services from planning to service & operation of plants, we develop custom-fit solutions for individual customer requirements.
