Welcome ...

Green Technologies Inc. was founded by Ralf-Peter Busse, Ingo Schaefer and Anja Busse. Ralf-Peter Busse is the owner and manager of Busse GmbH Germany that developed the Busse MBR system and holds the patent. An independent engineering firm Busse GmbH has over 25 years of experience in the area of plant construction, especially the commissioning of industrial and waste water treatment systems. As a result of this extensive know-how the membrane activated sludge treatment process for the treatment of on-site waste water was developed.

Ingo Schaefer has been working since 2002 to increase the interest and awareness for the decentralized waste water treatment with membrane technology in the US and to get the Busse system certified, approved and established in North America. He is a US citizen based out of Chicago, Illinois.

Anja Busse owns and manages the German company Busse Innovative Systeme GmbH that produces the Busse MBR systems and distributes them within Europe.

The Busse Innovative Systeme GmbH is the current production facility for Busse MBR systems certified by NSF International. In the future it is planned to also establish a production facility in the US to manufacture the Busse small scale waste water treatment systems with MBR for the North American market.


MBR sewage treatment systems designed for 250 to 2000 Gal/d

The small scale sewage treatment system BusseGT with membrane bioreactor technology (MBR) turns domestic waste water into useable non-potable water that meets all reduction standards.

Wastewater Recycling

The domestic waste water from decentralized and centralized buildings is recycled by the Busse membrane bioreactor technology and can be re-use as non-potable water, for example for toilet flushing or garden irrigation.

Closing this ecological loop is not only protects the environment and saves drinking water resources but also results in cost savings.

Special Applications

The application range of the BusseGT systems compasses solutions for yachts, theatre & restaurant ships, house boats, hotel resorts, campgrounds, historical buildings, like castles and palaces as well as mobile container systems. The MBR technology is even used for waste water free fish farming.
