Asker, 01 July 2021, 12:46 CET

Grønn Vekst, the Recycling sub-segment of Cambi Invest, has been awarded a contract for handling biosolids by the municipality of Bergen, Norway. Following standard public procurement procedures, the contract is expected to be signed after a notice period expiring 12 July 2021 (Norwegian ‘karenstid’).

The biosolids contract in Bergen is among the largest regularly on tender in Norway, and Grønn Vekst is currently holding it. The new contract has an estimated value of NOK 16 million per year. Its firm duration is two years with two options for one-year extensions, for a maximum of four years. The total estimated contract value, including options, is NOK 64 million.

 “Winning the biosolids tender in Bergen is an important milestone for Grønn Vekst in 2021, securing a significant contract for the coming years. We are pleased that our services during the past four years are appreciated by the municipality and remain the most competitive in the market. We look forward to the continued collaboration”, said Bernd Anders Keller, CEO Grønn Vekst.

In the tender award criteria, environmental aspects were weighted 50%. The Grønn Vekst solution is to transport the pasteurised and dewatered biosolids from the Rådalen biogas plant for application as a soil improver to farmland, partially substituting mineral fertiliser. Part of the biosolids is currently transported emissions-free by train to Eastern Norway before utilisation on farmland. Grønn Vekst is considering opportunities to produce peat-free soil locally in the Bergen region. 

The start date is set for 1 January 2022, upon expiry of Grønn Vekst’s current contract for the same services.
