The International Solid Waste Association (ISWA) is a global network dedicated to promoting and developing sustainable, professional waste management and supporting the transition to a circular economy. Its vision is a world with no waste, where materials are reduced and reused, waste is collected and treated responsibly, and residual materials are safely disposed of to protect public health and the environment. ISWA brings together national and other members, regional chapters, partners, sponsors, and waste-management professionals to share knowledge and encourage international collaboration.

The association’s work spans topics including recycling, biological treatment, waste collection and transport, energy recovery, hazardous and healthcare waste, landfill, climate change, governance, and marine litter. It supports projects, task forces, working groups, and a scholarship programme, and provides resources such as a knowledge base, publications, technical collections, and the Waste Management and Research journal. ISWA also offers member and sponsor opportunities, professional events, webinars, training, awards, and the annual World Congress.
