Demo Showcase of Recycling at the Source of Agro-Industrial Wastewater Into High Value-Added Products Through a Reinforced Territorial Symbiosis

To innovate in water treatment and waste recovery, companies from the Victoriaville industrial park, together with the City of Victoriaville, its economic development corporation and academic partners, are pushing back the limits of industrial symbiosis in Quebec through a circular innovation project aimed at the optimal use of resources at each stage of the life cycle.

This project consists of using the thermal, organic and mineral potential of the effluents from these industries to heat a greenhouse and produce microalgae. In addition to cleaning up the wastewater, the latter will be thermoformed into tens of thousands of containers with improved compostability for the needs of the companies in this same industrial park. The whey from one of these companies will be converted into bioethanol and other products for which the same companies in this park will be clients. A market garden production coupled with the microalgae cultivation system will complete the loop producing more than three tons of vegetables for the citizens.
