The idea to build ökoStrom – a biogas power plant – came in 2000. Now it collects sewage and liquid waste from agriculture in huge tanks. The mixture is then sealed into tanks and under an anaerobic process it produces biogas that produces electricity as well as a little bit of heat. The company, together with locals, decided to use better technology for emission extraction from the escaping air. | The idea to build ökoStrom – a biogas power plant – came in 2000.

SEEG, the last of the trinity, is responsible for biodiesel production from rapeseed. Biodiesel is used by local farmers but mainly by public transport companies and SEEG’s trucks. In addition, it also powers a biogas unit and local heating. There is also the possibility of using cooking oil as an additional material. A few years previously restaurant chains were happy to get rid of used cooking oil but later on its value was recognised and competition between biofuel companies arose, and so its price increased. | SEEG, the last of the trinity, is responsible for [[biodiesel]] production from rapeseed.

Because of the lower price of electricity, the companies are not only dependent on subsidies and other new investments must be found. Therefore, there is new PV power plant on the field next to the site. Even more efficient is the idea to build a glasshouse with organic vegetables and PV panels on the roof, which is better subsidized. | Because of the lower price of electricity, the companies are not only dependent on subsidies and other new investments must be found.
