The WasteWater Exchange© , W2AREX® collects, filters and matches offers and demands of wastewater by- or recovered products to secure the analysis (e.g. for early warnings of future outbreaks of corona virus)  and the up-cycling of wastewater.

Our matching services enable to plan activities and/or not miss any opportunities to: 

  • off-take products derived from wastewater; 
  • sell WasteWater by- or recovered products;
  • deliver and be rewarded for WasteWater supplies.


Our company reserves its rights to accept or refuse some requests. Users of our solution authorise our company to use their data for matching, rewarding and tracking purposes.
