Development of a dynamic circularity indicator for wastewater treatment plants taking into account local territorial specificities

Wastewater treatment plants are traditionally built to protect human health and natural ecosystems. The principle is based on a linear chain of physical, chemical and biological processes to remove pollutants and contaminants from water, in accordance with regulations. This principle is not conducive to the circular economy concept. Yet these materials are potentially resources that can be exploited according to local and cultural conditions. By developing a dynamic indicator of circularity while complying with environmental regulations on treated water discharges, the project aims to provide decision-makers and managers with a dynamic tool for improving the implementation of circular economy concepts in the design and management of produced and recovered materials.
