Ecomondo is Europe's leading trade fair dedicated to the circular economy, renewable energy, and environmental technologies. Now in its 2026 edition at the Rimini Expo Centre (3–6 November), it brings together over 1,500 exhibitors from around the world and more than 130,000 professional visitors across four intense days of conferences, exhibitions, and networking. The thematic areas cover the full spectrum of sustainability: waste management and material recovery, water treatment, environmental remediation, bioeconomy, energy efficiency, and industrial decarbonisation. The Scientific and Technical Committee — made up of over 100 international experts — coordinates a programme of 200+ scientific sessions and workshops. Ecomondo is also an institutional reference point, hosting government delegations, environmental agencies, and international bodies such as UNEP. For professionals, companies, and researchers in the environmental sector, it is the essential annual appointment.
