Wastewater = a resource that everybody generates everyday
Wastewater = a valuable resource when answering certain criteria
Wastewater = enabling massive, cheap and real time virus detection for early warnings

UNEP/UN Habitat wastewater definition

  • black water (excreta, urine and faecal sludge)
  • greywater (kitchen and bathing wastewater),
  • water from commercial establishments and institutions, including hospitals; industrial effluent,
  • stormwater and other urban run-off; agricultural, horticultural
  • aquaculture effluent. 


About 380km3 of municipal and 600km3 of industrial wastewater is produced every year and is  full of valuable substances like phosphorus, nitrogen and potassium. 

Transforming wastewater locally enables us to secure the sourcing of clean water, renewable energy, bio-fertilisers, polymers and other basic needs. In 2010 Prof. Willy Verstraete, environmental biotechnologist at Ghent University, calculated that every 1,000 gallons of wastewater contained the equivalent of $1.88 worth of fertilizer, energy as methane, and clean water. Since then, new technologies enable wastewater to be transformed efficiently into polymers, biogas, biofuels, bio-cements, clean water…etc and resources such as phosphorus can be recovered. In addition to the leverage effects of wastewater transformation on health, biodiversity and ecosystem services and resilience; using them as production inputs can give competitive advantages. Most of those wastewater by-products are indeed cheaper, locally available and with a high value, not limited to environmental benefits.

To scale-up wastewater transformation (into energy, fertilisers, clean water, bio-cements …etc…) our matching services are backed-up by  our rewarding services valuing wastewater according to the quality enabling efficient up-cycling.
