Working Group
Governance and Legal Issues
The Working Group on Governance & Legal Issues (WGGLI) serves as a platform for knowledge exchange and as the principal resource to ISWA on legal issues related to waste and resource management. The overall interest for the Working Group is the exchange of information and views on legal aspects concerning hot topics in waste management. Currently there is much focus on EU-waste legislation, environmental responsibility and the legal aspects of different kinds of public private partnership.

As presented in ISWA 2019 World Congress in Bilbao, the working group, with the kind support of Expra, has created a collection of papers on the history and current status of EPR programs and producer responsibility programs around the world. Click here to explore the EPR Library.
