The Rejuice project's main goal is to develop at least three sustainable and economically interesting value chains for processing and reusing the liquid fraction from green waste streams.

The project focuses not only on roadside clippings and grass but also other common green waste streams such as tomato stems, leek waste, flower stems and duckweed. This means reuse (Re) of sap streams (Juice), but also more efficient use of raw materials (Rejuice = Reduce).

Specific objectives:

  • developing a green residue calendar
  • optimising the refining process
  • optimise promising products in various application areas (namely alternative proteins, microalgae, biodegradable plastics (PHA plastics), bio-fertilisers and biogas)
  • improving logistics
  • testing fermentation techniques
  • applying for end-of-waste status. 

ReJuice aims to build a bridge between knowledge institutions, industry, government and citizens, with co-creation clusters and an advisory board. The opportunities for circular and bio-based economy, as well as the importance for achieving climate goals, make this project crucial for both Flanders and the Netherlands.
