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.

Our plants power the green value chain

Bigadan owns and operates a number of biogas plants that, every day, convert large volumes of organic waste into green energy, useful residues, verifiable CO₂ reductions and recirculate essential nutrients back to agricultural soil.

We collaborate with agriculture, industry, utilities, and municipalities to deliver solutions for responsible waste management, local energy production, and the supply of biogas, biogenic CO₂, and fertilizers. Because we own the entire value chain, we can design and tailor our plants to handle even the most demanding biomasses.

Each plant is technically advanced, reliable in operation, and fully integrated into our circular bioenergy model. We handle everything ourselves—from sourcing and process control to upgrading and distribution—and can document the climate impact end to end.

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.

A network of green plants

Behind our solutions is a portfolio of modern biogas facilities that we own and operate—across the country. Every day, they convert large volumes of organic waste into green energy and circular fertilisers.

“Our job is to make the complex work simply—so waste becomes energy with measurable impact.”
