The International Solid Waste Association (ISWA) is an international network of waste professionals and experts from around the world whose mission is ‘To Promote and Develop Sustainable and Professional Waste Management Worldwide and the transition to a circular economy.’  ISWA hopes to achieve this by bringing together waste experts from around the world to network, create best practices, produce industry reports, as well as publishing its own scientific journal Waste Management and Research.

The Environment and Resources Authority is a Silver Member of ISWA, giving it right to actively participate in ten working groups dealing with solid waste on a global level.
