WasteWater is a valuable resource that everybody generates everyday.
Transformed wastewater enables to reduce risks and production costs.
Virus detection in WasteWater enables early warnings, monitoring and tracking of viral outbreaks.

The providers of wastewater get Back2You Rewards

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 more efficient than the classical alternatives.

About 380km3 of municipal and 600km3 of industrial wastewater are produced every year and are  full of valuable substances like phosphorus, nitrogen and potassium. Approximately 80% of wastewater is still not treated and the balance often not transformed efficiently. 

To scale-up the necessary wastewater transformation (into energy, fertilisers, clean water, bio-cements …etc…) our matching services are backed-up with our Back2You services rewarding wastewater of quality enabling efficient up-cycling. Our Back2You Rewards create the intersection between the W2AREX market participants for optimal up-cycling with Zero Waste, wastewater-based epidemiology and stress-tests of interdependencies. 

Our Back2You Rewards give the following advantages :

– the producers of goods improving upgradability or reusability  of this vital raw material (e.g. the biodegradable laundry soap) can get part of the margins of wastewater circular economy enabling them to become more competitive, 

– the suppliers of wastewater with optimal quality for efficient and profitable transformation (mainly into renewable energy, clean water and bio-fertilizers) 

  • their expenses for wastewater treatment are reduced or eliminated, they therefore become more competitive 

  • they can exchange their wastewater against goods or services from our list of Back2You rewards while they contribute and benefit to a cleaner environment reducing uncertainties

  • they benefit virus detection early warnings, monitoring and tracking reduce : they can be labeled for their contribution to public health;

– the (public) procurements,  financing or trading of goods and services prioritising inputs from transformed wastewater can benefit directly from the rewards and indirectly via the leverage effects.  For example; our rewards can be allocated to banks active in financial inclusion or in micro-credits to equip houses to enable more wastewater transformation: the reimbursement of micro-credits will be directly via the valued and rewarded wastewater of the credit takers. 

The Rewards can be exchanged against:
–  products generating biodegradable residues and adding value for circular economy;
– goods or services with inputs from wastewater;
– products recovered or made from wastewater. 


Those advantages can be cumulated: for example, a producer of biodegradable cosmetics or soaps can:

– get funds to become more competitive and therefore increase its market share (branding possible) if the related wastewater enables efficient up-cycling;

–  enjoy alerts to get inputs (e.g. vegetable oil thanks to bio-fertilisers from wastewater) made with wastewater by-products internalising externalities and available at cheaper rates than classical alternatives;

– receive extra revenues and/or additional advantages or compensation if matched within our network. 

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.
