The IWWG runs several task groups on a range of topics. The aim of these task groups is to coordinate interdisciplinary research and experience on these topics and discuss and disseminate related results.
In order to join the task groups an IWWG membership is required. Groups typically meet once a year, mostly in the context of an IWWG conference.  The outcome of the scientific work within the groups is disseminated via the official IWWG journal Waste Management, in monographs or special publications or presented in the framework of conferences or workshops.

In order to harmonise, coordinate and facilitate the activities of the task groups, the task group leaders nominate two chair persons. In October 2017, Evangelos Gidarakos and Maria Aivalioti (both from the Technical University of Crete, Greece, leader and co-leader of the TG Industrial Waste Management) have been appointed by the Board as TGs chair and co-chair.

At present, the task groups listed on the left hand side are operational. Select individual groups for detailed information on their members, aims and objectives, current tasks, scheduled meetings and contact details.
