Lundsby Renewable Solutions is leading the ongoing upgrade of Langaa Bioenergi – a project that supports Denmark’s transition toward sustainable, CO₂-neutral energy.
All work is being carried out while the plant remains operational, ensuring minimal downtime.
Tank renovation:
The existing storage tank is being transformed into a primary reactor tank. The old membrane has been dismantled and the tank cleaned, repaired, and insulated. Several new service hatches and masts have been installed to improve mixing efficiency, and an external heat exchanger will soon be connected.
New piping system:
A completely new piping network is being established, connecting both existing and new solid feed systems. The upgrade also includes new raw slurry and substrate lines, as well as a new gas pipeline designed to enhance overall reliability and reduce system vulnerability.
New solid feeding system:
The project features the installation of a new Premix line and BIG-MIX feeding module, housed within a newly constructed, insulated technical building.
Current project status:
Pipeline installation is nearly complete. The storage tank has been taken out of operation, insulation work is in progress, the technical building is being erected, and new hatches have been installed.
Next steps:
In the coming phase, the external heat exchanger will be connected, the new membrane measured and installed, the technical building completed, and the new feeding system commissioned.
This project is a great example of how existing biogas plants can be modernized to meet future energy demands – ensuring continued delivery of sustainable, CO₂-neutral energy.
