The Danish Finance Minister Kristian Jensen has now officially inaugurated Denmark's first organic biogas plant.

Representing an investment of DKK 130 million (≈ EUR 17.4 million), the Nature Energy Månsson biogas plant in Brande converts ecological chicken litter and vegetable waste to ecological biomethane/green gas for injection into the national gas grid.

Renew Energy has been a responsible process advisor and also been the supplier of core biogas plant units including a receiving section for solid biomass.

"It has been exciting to take part in the design, engineering and construction of the Nature Energy Månsson Biomethane Plant. Although Renew Energy has many years of experience in designing biogas plants, the challenge has been that no plant is identical. That is why it has been important to use our long experience and know-how to design a flexible and well-functioning plant. New biogas plants require much higher flexibility regarding raw material composition. As a result the project has invested in a large solid biomass receiving section, where a crane / grabber mixes up the solid biomasses before it is sent into a premix system that size-reduces the biomasses and mix it with a reflux stream of digestate to form a pumpable mixture that is sent into the biogas reactors. Pumpable biomasses such as food waste / industrial waste, glycerine and manure are introduced to the reactors via separate feed systems" says project manager Jan Thorup Hansen, Renew Energy and supplements:

"We have built the reactors with a pump room in between the three reactors so that maintenance and service are easy and convenient. With an external heat exchanger for each reactor we ensure an optimal and very stable temperature in the reactors"
