Solid urban waste (SUW) is an abundant source for circular products production, but it is generally not exploited. In fact, over 500 kg of municipal waste per capita were generated in Europe in 2020, while only 45% was recycled.

The proximity of resources and people, a sufficient scale for effective markets and the ability to shape urban planning and policy are key factors for cities to achieve advancements in this area.

REDOL has been conceived to take advantage of this scenario and transform cities into hubs for circularity that implement zero residues strategies while fostering industrial-urban symbiosis (I-US) approaches among local and regional actors.
