CiNURGi Support Center for Recycled Nutrients Fertilizer production on the road in Sweden during summer of 2025

As a support center in CiNURGi project, RISE aims to support piloting of solutions for developing recycled nutrient fertilizers. The focus is on transforming raw materials like manure, sewage sludge, food industry residues, and agricultural by-products into valuable fertilisers that can replace mineral-based alternatives.

As part of this effort, a mobile container pilot has been introduced to support testing of raw material separation, a crucial preprocessing step in the fertiliser production process. By refining separation processes, the aim is to ensure maximum recovery of nutrients such as nitrogen and phosphorus while minimizing waste.

The RISE team has installed a decanter centrifuge onto a mobile set up, which can be transported by truck to any wanted location to conduct tests on the materials at hand. This facility provides the means to evaluate separation efficiency for different substrates, test various processing inputs like polymers, and perform solid/liquid separation to prepare for further processing. Further processing could be pelletising of the solid phase or membrane separation of liquid. These steps are essential for the formulation of high-quality fertilisers derived from recycled nutrients.

The CiNURGi team at RISE is currently fine-tuning the pilot’s operations and in the summer of 2025 the mobile container will be used to conduct tests in Sweden. This initiative aims not only to enhance nutrient recycling but also to enable external stakeholders to explore the benefits of sustainable fertilisers.
