ReLEAF and UPSTREAM are both EU HORIZON JU Innovation Action projects. ReLEAF aims to develop bio-based fertilizers that can compete in the European and global markets, create new value chains and reduce the environmental impact of urban and agricultural waste. UPSTREAM aims to improve the cleanliness and water quality of European rivers that flow through several major European capitals and into five sea basins. Both have an interest in wastewater treatment plants.

Specifically, they are keen to promote the transition of wastewater treatment plants into circular economy hubs for resource recovery. It's logical: ReLEAF wants to test new technologies to recover nutrients, biostimulants and other products from bio-wastes and UPSTREAM wants wastewater treatment plants to remove microplastics from the water before it reaches rivers and send it for recycling.

They are now gathering input on key messages to support the transition of wastewater treatment plants into circular economy hubs for resource recovery. It may seem that this is an idea which doesn't need advocacy but unfortunately - and as usual – it's not simple. Short-term public procurement contracts, rigid legislation and limited public awareness are barriers to this switch. Both projects are flagging up the need to extend contract durations, allow for real-world pilot testing and foster greater public engagement in order to foster a more sustainable and circular water sector.

Have a look at their joint message and give them your input!
