Project objective:

The ReNuW-Hubs project improves nutrient (phosphorus and nitrogen) recycling and water reuse from community wastewater, including human sludge, using a physico-chemical treatment system housed in a 20-foot mobile container (MWWTD). The project enhances the system’s efficiency and promotes the use of recycled nutrients and reclaimed water for irrigation by farmers, horticulturalists, and municipalities.

Project results:

Improving the Mobile Wastewater Treatment Device (MWWTD) will create better opportunities to recycle nutrients from community wastewater, thereby supporting the use of recycled nutrients and reducing the need for natural fertilisers. Similarly, using reclaimed water lessens the demand for potable water in irrigation. Both of these recycled resources will be produced for commercial use. The mobile technology also offers a flexible solution for remote areas that lack adequate wastewater treatment capacity due to high seasonal variation in wastewater generation-for example, popular tourism destinations. In addition to the technical development, the ReNuW-Hubs project will examine consumer attitudes towards recycled resources derived from human-based wastewater. Based on this research, the project aims to support and influence positive changes in these attitudes.

The project is implemented within the Central Baltic cross-border cooperation programme 2021–2027.
