Expansion of the industry membership body extends reach to an international group of 7000 members
The Chartered Institution of Wastes Management (CIWM) has announced a significant expansion in its global focus with the acquisition of the Circular Economy Institute (CEI) and its non-profit arm, the Circular Economy Club (CEC). The strategic move aligns with CIWM's objectives to develop professional standards beyond the UK.
The CEC currently has over 7,000 members across 140 countries, encompassing a range of businesses, governments, financial institutions, and academic entities. The club offers a free membership and operates more than 280 local clubs worldwide.
The incorporation of both CEI and CEC under CIWM's umbrella aims to deliver wider benefits to the members and customers of each organisation. CIWM, CEI, and CEC will operate independently, while offering their members a wider range of thought leadership, collaboration opportunities, and knowledge sharing. This integration will expand its international impact and membership size, with CIWM focused on supporting the ongoing growth of both CEI and CEC.

Sarah Poulter, CEO of CIWM, commented: “Whilst we recognise that each of the organisations we have brought together will have their own distinct priorities, there is also a significant degree of common thinking and a shared desire to better manage the Earth’s finite resources. The creation of this group will facilitate the growth of a powerful and respected global community with the scale and resources required to drive meaningful and lasting change.
“We look forward to supporting CEI in its mission to promote the highest standards of practice in the circular economy field, and in building the strong international leadership needed to shift from linear to circular practices. We are also extremely excited by the opportunity to grow the CEC community and cement its position as the primary platform for ambitious professionals committed to a circular future"
Founded by circular economy pioneer Anna Tari in 2012, CEI offers a range of training courses, workshops, and seminars in over 30 countries. Beneficiaries of CEI's training include organisations like the United Nations One Planet Network, Harvard School of Design, and London City Council.
Anna Tari commented on the transition: “The recent growth of the CEI and CEC means the time is right to hand over their custodianship to those with a shared purpose and strategy. With 125 years of experience, CIWM has proven itself as a highly successful membership organisation and training provider which has been instrumental in developing and promoting the more sustainable use of resources. It was this, together with its clear commitment to developing the circular economy, that led me to approach them.
“I am confident that their support for the CEI and CEC will ensure they retain their individual identities, keeping each community’s best interests at heart. The CEI and CEC have come a long way in a short space of time and I’d like to thank everyone who has been involved in this journey. I look forward to witnessing the next stage of its evolution and growth and will continue to be involved as part of the CEI steering group.”

How will the government and DMOs address the challenges of including glass in DRS while ensuring a level playing field across the UK?
There's no easy solution to include glass in the DRS while maintaining a level playing field. Potential approaches include a phased introduction of glass, potentially with higher deposits to reflect its logistical challenges. The government and DMOs could incentivise innovation in glass packaging design and subsidise dedicated return points for glass-handling. Exemptions for smaller businesses unable to handle glass might also be necessary. Any successful solution will likely blend several approaches. It must address the differing priorities of devolved administrations, balance environmental benefits with logistical and cost implications, and be supported by robust consumer education campaigns emphasizing the importance of glass recycling.
