Vestergaard Bioenergi, Denmark

Vestergaard, a cattle farm in Rødkærsbro in Denmark, today has a large number, of cattle that produce large amounts of manure and cow dung. Vestergaard’s owner made an agreement with a nearby Arla dairy to supply biogas to the dairy and thereby convert agricultural waste into a stable income.

The biogas plant was put into operation in March 2017 and has been running successfully ever since.  The daily operation of the biogas plant is carried out by the farmer himself and a half-time assistant.
