Important results from the project
The project has successfully achieved its goals. A variety of biomaterials was investigated to assess the potential for recycling the contained nutrients. A chemical process that effectively recovers high purity potassium salts from bio-derived wastes was developed. The performance these fertilizers was successfully validated in pot trials. The LCA analysis showed that the recycled fertilizers have a significantly lower environmental footprint compared to those produced via conventional mining.
Expected long term effects
There is high demand for circular solutions and sustainable sources of raw materials. The future availability of fertilizers is a top priority since they are critical for crops and for sustaining life. Implementation of the developed process can significantly reduce the amounts of bio-derived materials discarded in landfills because of their contamination. In addition, it provides an alternative source of high purity fertilizers with well-defined chemistry and better climate footprint.
Approach and implementation
All the actions and tasks were carried out during the project timeframe defined at the start of the project. No major deviations or setbacks occurred, and the project developed as intended. The collaboration between the members of the consortium was very good, leading to a successful completion of the actions and milestones. Other collaboration areas between partners were identified, and these are being further explored outside the project, for example in new projects.
