Webinar: Value-adding sewage sludge in concrete

Ramboll is part of a team working on a state-of-the-art technology to make concrete more sustainable by using wastewater sludge as a key ingredient. Learn about the method and how the project is progressing in a webinar on October 2nd.

People worldwide are trying to find a way to make concrete production more sustainable. The ‘Ash2Phos’ process, where phosphorus is recovered from sewage sludge, leaves a silicate sand residue that can be used as cement-replacement in concrete. A team consisting of EasyMining, Ragn Sells, Technical University of Denmark (DTU), Ramboll, and BIOFOS is therefore working on further development of this new type of concrete.
You can get a first-hand insight into the project by participating in a webinar on October 2nd from 9-11 am. The team will present the project and talk about its sustainable dimension and future perspectives.
Katrine Orland Led is Ramboll’s representative in the project. She will present the market analysis giving the view on how the value chain can cooperate to lower CO2 emissions and make concrete more sustainable.
The team expects that a full-scale production can be ready by 2023-24.
