The WasteWater Reuse Exchange



  • 1kg of refined cane sugar has an average water footprint of about 1400 liters (see The Buyer of treated wastewater might be the farmer or its client buying sugar to be produced partialy with recycled wastewater as per ISO 16075.
    If only 1% of water used to produce sugar comes from treated wastewater, a cargo of 20'000 tons of sugar can cover sanitation infrastructure for 13'698 people living near the sugar plant (1,5 m3/ton water footprint per 20'000 tons / 100 for only 1% of water used from treated water = 300'000m3 = 60 liters wastewater of 13'698 inhabitants during 365 days).

  • The Buyer puts his request on the W2AREX┬«
    The Seller of recycled wastewater responsible for collecting and sanitizing wastewater puts his offer of treated wastewater on the W2AREX®
    The W2AREX filter both the offer and the demand of treated wastewater to be delivered and off-taken from an agreed date.

  • Our algorithms using artificial intelligence are then checked with wastewater supplies even if related infrastructures do not yet exist. Contracts for wastewater supplies include wastewater quality request to enable efficient circular economy and sharing of wastewater valorisation.

  • When the 3 commitments are matched and organized though our services, the wastewater valorisation can take place to deliver irrigation water for the cane, potable water for Human rights and renewable energy. The buyer of the sustainable refined sugar gets the invoice for his order with the deduction of the treated wastewater amount (pre-financed).

  • Reporting include proposals of goods/services available for the value of shared profits of the wastewater valorisation.
