WELTEC BIOPOWER orders first Greenvironment plant for large biogas park in Barsikow
WELTEC BIOPOWER orders first Greenvironment plant for large biogas park in Barsikow

• 1st installation of a microturbine plant in the field of biomethane upgrading
• Long-term technology cooperation with WELTEC BIOPOWER

Berlin, 17th January 2011 – WELTEC BIOPOWER GmbH, the world market leader in the production of stainless steel biogas plants, has placed an order for the first microturbine combined heat and power plant from Greenvironment GmbH, a 100% subsidiary of Greenvironment plc.

Greenvironment will install a CHP plant with a CR600-microturbine and the SCADA system for remote monitoring in a large biogas park (24,000 square meters) in Barsikow (Brandenburg), about 100 kilometers to the west of Berlin. Based on the input materials corn, whole crop silage and dry chicken manure 8.4 million standard cubic meters of biogas and 3 million standard cubic meters of biomethane will be produced here annually starting in the summer of 2011.

In this biogas project, microturbines are combined with a biogas upgrading plant. The thermal energy
contained in the exhaust stream of the microturbine is used as process heat for the biogas upgrading
plant. The treatment is based on the principle of chemical wash (amine scrubbing). The goal is a
self-sufficient process heat supply of the upgrading plant by a head load controlled CHP with
integrated microturbines. The generated electricity is fed into the grid of the local utility. The
amount corresponds to an electrical capacity of 2.2 megawatts.

"During the processing of biomethane, the process energy (water) needs to have a temperature of 140 degrees Celsius. Therefore microturbines offer a clear competitive advantage thanks to their high thermal efficiency, which helps us to significantly increase the overall economics of the biomethane production", says Robert Tholen, technical director of WELTEC BIOPOWER. Further advantages are the compact and modular design of the package that can be upgraded as needed.

"Greenvironment has quickly developed solutions that have all facilitated a good connection to the existing biogas upgrading plant", Robert Tholen stated the reason for awarding the contract to the Berlin-based technology specialist.

"This initial contract by WELTEC BIOPOWER is a good start into 2011. In addition to that, negotiations with other clients regarding further major contracts are also well advanced. Therefore we expect a significant jump in revenues this year", commented Radu Anghel, managing director of Greenvironment GmbH.
