This project focuses on scaling circular potassium recovery by turning bioindustry waste into clean, high‑quality fertilisers—supporting a more resilient and sustainable nutrient supply in the Nordics.
Potassium and phosphorus are vital nutrients, yet fertiliser production today relies largely on mined resources while valuable nutrients are lost in waste streams. Ashes from fish feed production and straw combustion can contain over 20% potassium, representing a significant opportunity to recover domestic resources, reduce import dependency, and improve circularity in Europe.
Building on previous research, the aim of this project is to establish the foundation for the first regional industrial implementation of a circular solution for clean and safe potassium fertilisers. EasyMining’s technology for potassium recovery will be optimised for these waste streams to produce high‑purity, heavy‑metal‑free potassium salts.v
Together with partners across the value chain, the project will evaluate the technical, environmental, and economic feasibility of large-scale nutrient recovery in Sweden and the Nordic region. Activities include process development and pilot-scale validation, agricultural field trials to verify fertilizer performance, life cycle assessment (LCA), and studies supporting future commercialization.
By transforming waste into valuable fertilizer products, the project contributes to a more resilient nutrient supply, reduced dependence on imported raw materials, and a more circular and sustainable agricultural sector.
