Bioenergy
We build and operate the biogas plants of tomorrow
With more than 40 years of experience, we design, construct, and operate biogas plants that turn organic waste into green energy and circular value.
Agriculture
From slurry to green energyWe work with farmers to turn livestock manure and residues into biogas, circular fertilizers, and documented CO₂ reductions—benefiting climate, soil, and local communities.

Metropolis
Local energy from local wasteOur metropolis concepts help cities manage commercial food waste efficiently and convert it into green energy and fertilizers—produced and used locally, with full traceability.

Industry
Plants for even the most complex biomassesWe are skilled at adapting our biogas plants so we can receive and digest even the complex organic by-products from industry. This creates strong partnerships and enables circular, efficient and reliable solutions at the local level.

Kalundborg Bioenergy
Turning insulin waste into energy
In partnership with Ørsted, Bigadan established a full-scale biogas plant, which we now operate. The plant converts organic residues from insulin and enzyme production at Novo Nordisk and Novonesis into sustainable energy.
“Our job is to make the complex work simply—so waste becomes energy with measurable impact.”
