Returns On Investment

Traditional investments in wastewater infrastructures limit their scope of pay back generally only via compliance (tariffs for sanitation/sewage services) and more recently with the integrated approach - water for energy and at energy for water.


The WasteWater Reuse Exchange goes further than that to give flexibility and returns to the investors notably as follows:

  • the investors have the choice to be reimbursed in wastewater by-products. In the context of today’s increasing water and other resources scarcity, this first refusal option is important;
  • increased access to water, sanitation and energy creates high leverage effects that can be allocated directly to the investors selling products enabling efficient wastewater reuse (e.g. cosmetics, detergents) or selling products with a link with the bio-refinery hub.
  • the margins of the WAREX are according the proactive organised off-takes of wastewater by products of the bio-refineries;
  • the transactional flows of traded wastewater by-products enable to identify the goods and/or services that will be produced competitively and with a high impact value chain. This visibility for reputation, competitiveness and sourcing security is key for investments strategies;
  • the redistribution of part of the dividends of the bio-refineries under the WAREX scheme to the suppliers of wastewater and organic wastes (see smart-meters, internet of bins…), enables investors producing or selling goods or services with inputs from wastewater by-products (energy, cooling water, fertilisers, …etc) to benefit solvency and market organisation thanks to monetised wastes;
  • investing via the W2AREX means acting for public interest and for a decarbonised economy: case by case, the related advantages (e.g. carbon credits) can improve the investment returns.
