KG is present on the market far beyond the boundaries of Germany.

Till today projects have been developed and realised in Great Britain, Hungary, the Czech Republic, Italy, Spain, Poland and Turkey. All challenges have always been met with expertise, dedication and reliability.

The international distribution of the biogas technology will continue to have a high level of importance. In times of globalisation and climate changes, challenges do not stop at national borders.

bwe biogas weser-ems GmbH & Co. KG was founded in 2000 by Eng. Klaus Hanneken and Eng. Johannes Gehlenborg. Prior to the establishment, both founder engineers were active in the biogas sector, bringing their know-how and expertise together.

The first biogas plant was built in 1997. Even before establishing the company bwe biogas weser ems the two engineers Gehlenborg (mechanical engineering) and Hanneken (civil engineering) planned biogas plants. These facilities treated fats, sludge and waste residual products from the food processing industry. The successful cooperation of the shareholders allowed the rapid evolution of the medium-size company.

In 2000, the new Renewable Energy Act in Germany facilitated considerably the demand for biogas plants installation.

With the amendment of the Act in 2004, the perspectives for biogas facilities increased. The interest in facilities treating renewable raw materials was growing.

In 2006, the first large-scale biogas plants were put in operation, such as the biogas park in Felgentreu in Brandenburg – a European milestone project unrivalled in both environmentally friendly and socio-political context.

Mid 2010, Johannes Gehlenborg resigned from the management board and subsequently the partnership as well, leaving Klaus Hanneken as the whole-owner of bwe biogas weser-ems GmbH & Co. KG since 2013.
