BioP-Rec

The project experimentally develops a new method for recovering phosphorus from wastewater. Soluble phosphorus is precipitated as struvite in the biological phosphorus recovery (BioP) wastewater process. Struvite is a fertilizer product containing phosphorus, nitrogen, and magnesium in a form that is usable by plants. The project also investigates the use of new precipitation chemicals and bio-based polymers.

Through the project results and communication activities, the aim is to further develop the BioP process and struvite production and to promote their adoption at wastewater treatment plants. The project supports phosphorus recycling from wastewater for plant use and improves the security of supply of current precipitation chemicals.

The project is part of the RaKi Programme of the Ministry of the Environment of Finland and is implemented in cooperation with regional wastewater treatment plants, biogas plants, as well as other chemistry and biochemistry companies and research institutions.
