Confidence across the entire value chain

We help you recycle your organic residuessafely and in a truly circular way — turning them into fossil-free energy and returning vital nutrients to agriculture. We collect, process, and utilise organic residues from cities, farms, and industries, converting them into biogas at our own plants.

For you, this means a fully integrated value chain with guaranteed off-take and complete traceability. We make sure your organic residues are put to optimal use and contribute directly to a fossil-free future.

The value chain

Organic residues

We receive your organic residues safely and efficiently – with full traceability throughout the process.

Biogas production

We digest the residues at our own plants and can adapt our facilities to handle even the most complex biomasses.

Green energy & nutrients

The biomass is converted into green energy for transport, cities, and industry, giving you secure and reliable offtake for your materials.

Metropolis, agriculture & industry

The green energy and recycled nutrients are returned to society – and the circular loop continues.

Guaranteed off-take

With our own biogas plants and strong connections across the industry, we can always secure a stable and reliable outlet — regardless of the type or volume of organic residues.

Handling the tough materials

We deal with what others can’t. Whatever the challenge, we find a solution — tailored, efficient, and with a sharp focus on compliance.

Full transparency

We offer complete traceability so you always know where your organic residues come from, how they’re treated, and the value they generate.

Our biogas plants turn food waste into energy, cutting CO₂ emissions by more than one tonne for every tonne processed. A single plant can reduce CO₂ emissions by over 250,000 tonnes per year.

Our services

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.

Full transparency and recirculation

We recycle organic residues into renewable energy. Processing at our own plants also ensures that essential nutrients are returned to farmland. This enables you to document safe and responsible recycling in your ESG reporting.
