SK Spildevand A/S has been working for a long time to find suitable recipients of PFAS-containing sewage sludge. A solution has proven to be very challenging, as there are not many plants with the necessary technology for handling. Therefore, SK Spildevand A/S has decided to build a local sludge incineration plant at the existing Slagelse Wastewater Treatment Plant. SK Spildevand A/S expects that the construction of a sludge incineration plant will significantly boost the natural and aquatic environment, thereby significantly reducing the discharge of PFAS, heavy metals and other pollutants into the natural and aquatic environment. Instead, the environmentally hazardous substances are incinerated in the sludge and the remaining residue could be used as a soil improver due to the content of phosphorus and carbon that improves agricultural soils and binds CO2. This tender includes the design, production, supply and installation of a sludge incinerator including drying (supply). A sludge incineration plant with an annual capacity of approximately 6,600 tonnes of sludge is required. The plant is to be classified as a single-tier facility, but is to be prepared for conversion to a two-tier facility in order to ensure the future treatment of larger quantities of sludge. In addition, the tender includes an option on a service agreement, which includes assistance and assistance to SK Spildevand A/S in connection with its use of the sludge incineration plant, but the service agreement shall not include spare or consumable parts. The service agreement is priced as an option that SK Spildevand A/S may choose to exercise. The fulfilment of the contract offered by the Process Supplier, including the fulfilment of the warranty requirements, shall not be conditional on SK Spildevand A/S exercising the option and entering into a service agreement with the Process Supplier. The tendered plant is described in more detail in the tender documents. Contract: A contract for the design, production, delivery and installation of processing plants is concluded on the basis of the draft contract which is part of the tender documents. This project – the construction of a sludge incinerator – also includes, inter alia, a contract for the construction of a building housing the incinerator, as well as installations, sewage pipes, surrounding fortifications and access roads, etc., which is put out to tender in a separate tender and the related turnkey contract. SK Spildevand A/S has assessed that the handling of interfaces, responsibilities and risks within each tender/contract is best placed with the turnkey contractor/process supplier, respectively. Further splitting of the project/contracts entails an increased risk for SK Spildevand A/S, including increased costs for construction management, etc., which is why SK Spildevand A/S has considered it appropriate not to split the project/contracts further. In the contract notice, the contracting authority has set the duration of the contract at 18 months. The contracting authority notes that this period reflects only the expected time of conclusion of the contract up to delivery and that the contract ends when each party has fulfilled its obligations under the contract.
