Aarsleff to build 'largest biogas plant in Northern Europe'

Per Aarsleff, a Denmark-based contracting company, has signed an agreement to develop what it is calling 'Northern Europe's largest biogas plant' on a 12 hectare plot in the Danish town of Tønder.

The contract value of the biogas plant in Tønder is approximately DKK300 million (€40 million). There is also an option to build a similar plant in Aabenraa town, bringing to total investment to DKK600 million.

The contract is to be carried out as a turnkey contract for Envo Biogas Tønder. The project is commenced by a design phase which is expected to be followed by a contract for the execution phase.

Per Aarsleff will carry out the civil engineering work, including earthwork and concrete work, whereas the technical installation contract, comprising electricity, pipe work and processing plant, is to be carried out by the subsidiary Wicotec Kirkebjerg. The process technology will be supplied by the German collaborative partner LimnoSun.

Work on the biogas plant has started, with completion expected within 22 months. The option for the second biogas plant in Aabenraa is planned with a staggered execution start of six months.
