Grønn Vekst retains major contract for municipal biosolids management for Bergen, Norway
Grønn Vekst, part of Cambi’s Solutions segment, has received an award notification from Bergen municipality, through Bergen Vann, for the continuation of a long-standing service agreement covering the handling and final disposal of biosolids, or digestate, from Bergen Vann’s biogas operations in Bergen.
Following standard Norwegian public procurement procedures, the agreement is expected to be signed after completion of the statutory standstill period, subject to no successful appeals.
Grønn Vekst thus preserves an important contract in Norway. Service delivery under the new contract is scheduled to start on 1 July 2026. The agreement is Grønn Vekst’s largest ever, with a firm duration of five years and three unilateral one-year extension options for the contracting authority, giving a maximum duration of eight years.
The total contract value, including all option years, places the contract in Cambi’s “Major” category for contract announcements, i.e., above NOK 200 million. The expected volume is expected to increase gradually during the period.
Under the scope, Grønn Vekst will receive digestate in Bergen, transport it by rail to Eastern Norway, and secure final utilisation through agriculture and Grønn Vekst’s soil production facilities. The logistics solution reduces long-distance haulage and limits CO2 emissions from transportation. Established agricultural and soil-production outlets will return nutrients and organic matter to productive use.
Bernd Anders Keller, CEO of Grønn Vekst, said:
“Grønn Vekst is pleased to be selected to continue supporting Bergen Vann with a robust and circular solution for biosolids from Bergen. The assignment is technically and logistically demanding, requiring reliable capacity, environmental performance, and secure downstream outlets. Our rail-based logistics and established network within agriculture and soil production provide a scalable solution that returns valuable resources to productive use.”
Bergen Vann is the agency responsible for water supply and environmentally sound wastewater management in the municipality of Bergen. The agency operates and manages municipal water and wastewater facilities in Bergen municipality and Bjørnafjorden municipality.
