Background & Scope

The IWWG set up the C&D Task Group to provide an international platform for C&D waste information exchange and dissemination; research and innovation; and practical applications for members and those engaged with the planning, procurement, design, construction, refurbishment, and demolition activities in the built environment.

This engagement provides IWWG members with a unique insight into policy and regulation updates; emerging methods and techniques; and the opportunity to influence policy and industry development.
  • Networking: knowledge sharing and exchange between research centres, groups, and individuals across the World to keep IWWG members informed on developments affecting C&D waste management in both construction and the wider built environment.
  • Knowledge transfer: C&D Task Group activities facilitate knowledge and best practice transfer between IWWG task groups on the one hand; and between business and the science-base, and businesses and across sectors on the other.
  • Conferences and events: IWWG rolling programme of conferences and events is designed to raise awareness, share knowledge and promote discussion on new and emerging WM topics, with specific discussions and workshops on C&DWM.
  • Publications: the majority of C&D Task Group activities culminate in the publication of joint journal and conference papers, guidance documents, and best practice case studies.
