United Circles – Zero-waste cities and decarbonised industries that support sustainable growth and resilient communities

United Circles - Implements a partnership of 44 partners across 16 countries & 1 United Nations body to connect to the Hubs4Circularity EU Community of Practice and to EU & global circularity, process industry & decarbonisation networks.

General Assembly: Athens 18-19. November 2025

The main objective of United Circles is to accelerate our progress to a fully decarbonised future without waste and with closed water loops. By fostering a problem-solving circularity culture, we address urban waste at its source and across process industries.

United Circles is leading the change by showing how cities and industries can work together to upcycle waste into value-added products. By connecting urban and industrial systems with a set of new technologies and collaborative models (Hubs4Circularity).
