Miljøvenlige mursten fremstillet med kommunalt spildevandsslam efter fosforindvinding

Project Details


As we move towards a circular economy, managing resources and innovatively utilizing waste becomes crucial. This project aligns with that vision.

The overall project goal is to investigate the possibility of using sewage sludge as a secondary resource for phosphorus extraction and then as a partial replacement for clay in producing bricks. As a by-product of wastewater treatment, sewage sludge is typically disposed of by spreading it on fields or incinerating it. However, these methods have limitations, such as restrictions on spreading sludge containing pollutants and challenges in sparsely populated areas where incineration may not be feasible. The proposed approach reduces the need to extract phosphorus from mines and lessens the demand for clay in brick production. This alternative could be particularly significant in regions where traditional disposal methods face constraints.
