All a question of technology.

Inside the fermenter at the ReFood biogas plant in Malchin: the bubbles on the surface of the biomass indicate that methane gas is being produced here.

When food waste arrives in the reception hall of a ReFood operation, the first step is crushing. In a subsequent step, packaging such as glass and plastics and other extraneous matter is removed. Before going into the fermenter of the biogas plant the organic waste is heated to above 70 degree Celsius for an hour in a hygienisation unit to sterilise it.

State-of-the-art
Our technicians continually strive to improve the technology deployed by ReFood. Generating biogas typically produces small quantities of hydrogen sulphide. ReFood filters off this harmful substance and feeds only clean biogas into the combined heat and power (CHP) plant. This not only ensures our employees are safe but also means that the emissions from electricity generation are significantly below prescribed limits. Our technicians are also working to produce biogas of the same quality as natural gas. This will open up other fields of application in future, such as biogas filling stations.

Besides, our plants:

• comply with the DIN EN ISO 9001 standard,
• are certified specialist disposal facilities,
• and are operated in line with our own HACCP policy (Hazard Analysis and Critical Control Point).
