The 2027 ISWA World Congress will take place at the WTC Rotterdam in the Netherlands from 27–29 September 2027.

The Congress welcomes everyone with an interest in sustainable resources, waste management, and the circular economy, including professionals from the public and private sectors, researchers, consultants, local authorities, and NGOs.

The theme of the 2027 Congress is Shifting Systems – Future Cities in Motion.

ISWA2027 explores how cities can become more resilient, circular and sustainable by transforming interconnected systems for waste, resources, energy and materials.

Six themes address the key shifts needed to shape the future of urban living:

• Organics and Biological Resource Management
• Waste Prevention, Sustainable Collection and Recycling Systems
• Managing Residual Waste through Energy Recovery and Landfilling
• Governance, Legal Issues, Financing & Ethics
• Ethics, Equity & Social Responsibility
• Resource Efficiency, Circular Design & Urban Mining
