Grønn Vekst, part of Cambi's Solutions segment, has been awarded a multi-year
contract by Sirkulær Bestiller for the transport, treatment and final management
of sewage sludge from municipal wastewater treatment plants in Bamble,
Holmestrand, Horten and Sandefjord.
 
Following standard Norwegian public procurement procedures, the agreement is
expected to be signed after a twelve-day standstill period following the award
notification (Norwegian "karenstid").

Service delivery starts on 1 February 2026 and runs for six years until 31
January 2032. The contracting authority holds two unilateral extension options
of one year each. Including options, the total contract value falls within
Cambi's "Major" category for contract announcements, i.e., higher than NOK 200
million. The annual volume is approximately 10,000 tonnes of biosolids.

Under the scope, Grønn Vekst will collect biosolids from participating plants,
transport them to treatment, and manage the digestate after processing.
Treatment will take place at the new Krogstad sludge treatment centre in
Lillestrøm, near Oslo, under a cooperation agreement established with Nedre
Romerike vann- og avløpsselskap IKS (NRVA) for this contract. The new facility
uses Cambi's thermal hydrolysis technology, supporting efficient biogas
production and high-quality downstream handling.

The procurement placed significant weight on environmental performance. Price
accounts for 70% of the evaluation, while climate and environmental criteria
account for 30%, with specific emphasis on biogas-based treatment, the upgrading
of biogas for transport, and low-emission logistics.

Bernd Anders Keller, CEO of Grønn Vekst, said:

"Grønn Vekst is grateful for being entrusted with this important contract, which
demonstrates our capacity, preparedness, and environmental credentials. In close
collaboration with NRVA, the solution will maximise energy recovery through
biogas and ensure responsible biosolids management. The team looks forward to
working with Sirkulær Bestiller and the municipalities throughout the contract
period."

Sirkulær Bestiller is a Norwegian contracting authority established to procure
treatment solutions for food waste and biosolids on behalf of its owners,
municipalities and municipal owned companies along the west side of the Oslo
Fjord from Drammen to the Grenland area. For this procurement, the participating
municipalities are Bamble, Holmestrand, Horten and Sandefjord.
