WOW!: Wider business Opportunities for raw materials from Waste water.


The WOW! project aims to make the transition to a more circular approach by matching supply and demand of cellulose, lipids and bioplastics (PHA) from sewage.

The following activities are part of the project:

  • Identify high potential value chains for raw materials from sewage.
  • Develop a Decision Support Tool that guides sewage treatment plants in their transition towards a circular approach on sewage.
  • Build and run three WOW! pilots to optimize and implement innovative recovery and upcycling techniques.
  • Create bioproducts made out of sewage, such as bioplastics, biofuel and bio-char.
  • Create national policy action plans and an EU policy roadmap.
