The WasteWater Reuse Exchange© , W2AREX® platform matches offers and demands of wastewater by-products to secure the transformation and valorisation of wastewater. The World Health Organisation is stating that every dollar invested in water can generate $34 leverage effects.


The more wastewater is transformed, the more nature can clean for free the environment, preserve the ecosystems and reduce greenhouse gas emissions.

This enables also to reduce costs and risks, create value and to generate new incomes and/or jobs.


Smart metered wastewater resources are valued according to the difficulty to treat them; the W2AREX enables:

  • responsible products to become more competitive than products generating heavy noxious wastes and/or to get financial incentives
  • suppliers of wastewater to get revenues and/or goods or services and/or financial inclusion or micro-credits for the value of their wastewater.


On the transformed wastewater purchase side, Products/Services produced with wastewater by-products can be traced towards a circular economy approach and reported for their positive impact.
