Short description
This contest comprises both disposal of the sludge, and transport of the sludge from the treatment plant at Søndre Follo Renseanlegg IKS. . It is only possible to submit tenders that cover both transport and disposal of the sludge.
The amount of sludge covered by the contract is estimated to be approx. 3,200 t / 3.500 t in 2022, but this can be reduced somewhat in the contract period as SFR will carry out an innovative project where a new type of biogas reactor will be tested. The amount of treated sludge will probably be reduced then by an estimated 300 t / 600 t based on a pilot that has been carried out. Note that SFR cannot give an exact figure now. There will be a reduction, but the amount is uncertain.
The produced sludge is split into four categories in accordance with the table in the regulation dated 4.7.03 no. 951 on fertiliser products, etc., of organic origin (the fertiliser regulations).
