At a dairy and arable farm in Den Bommel (NL), biomethane is produced and delivered to the natural gas network. In the Microferm digestion plant built by HoSt, 8,000 tonnes of cattle manure is digested annually. The produced biogas is upgraded to natural gas quality and then fed into the natural gas network. The amount of produced natural gas is 180,000 Nm³ annually, which is equivalent to the consumption of 125 households.

It is the first plant in the Netherlands where 100% manure is digested in combination with the production of biomethane on this scale. The plant consist of a Microferm digestion tank, a gas tight after-storage, a container with the biogas upgrading and control panel, and a skid on which the biogas treatment, manure heat exchanger, and heat pump are mounted.
