Circul’R was established in 2017 and is now a leading voice on the circular economy in France and internationally thanks to the close links it has established with all stakeholders: large companies, VSEs/SMEs, producer responsibility organisations (PROs), public institutions and local governments. Circul’R is firmly committed to supporting organisations - whether public or private - in their transition to circular models and modes of operation.

To achieve this mission, Circul’R works at three levels: 
1. Training - Raising awareness of the circular economy among managers and employees and enhancing their skills in this area.
2. Leading coalitions - Creating and leading coalitions of committed players to set new standards in circularity.
3. Consulting - Support private and public organisations in setting up circular economy projects, from roadmap to operations.

Circul'R has a team of 40 circular economy experts.

At Circul’R, he now leads projects with private companies and public authorities in France and internationally, supporting the design and implementation of circular strategies. He actively facilitates dialogue between sectors to overcome barriers to circularity, notably through coalitions and collaborative projects. As part of the ECESP Coordination Group, he aims to foster cross-sectoral cooperation and share field insights to advance Europe’s circular transition.

Academics for Circular Economy (ACE) is an international non-profit network connecting PhD researchers, postdocs and early-career academics working on circular economy topics. ACE strengthens research capacity through peer learning, mentoring and skills development in research design, stakeholder engagement and science communication. Their mission is to bridge the gap between academic research and practical action by connecting researchers with policymakers, industry and civil society actors. Through collaborative projects, workshops and policy dialogues, ACE fosters high-quality, interdisciplinary research that advances circular economy implementation and systemic sustainability transitions globally.

After over a decade in industry, Priya Saikumar has transitioned to academia to complete her PhD on Circular Economy Transitions in the Electrical and Electronic Equipment sector at the University of Oxford. Priya and seven other members met through an online Circular Economy PhD peer community, and recognised that research and practice in the field often remain siloed. As a result, valuable, high-quality doctoral insights are overlooked and reinvented for decision making in policy and industry. To address this, they founded Academics for Circular Economy, a non-profit that bridges academia and practice by making rigorous research accessible to practitioners while also enabling PhD scholars to apply their expertise and break free of the publish-or-perish cycle.

He is also a member of the United Nations Environment Programme on Product Life Extension. He has welcomed the latest version of circular economy metrics for business from the World Business Council for Sustainable Development, which starts to account for the CO₂ savings from remanufacturing and refurbishment processes. He participates in the World Steel Association working group on remanufacturing; the WSA was the first materials organisation to acknowledge the sustainability benefits of using durable materials in products designed for extended life cycles. Wherever possible, David promotes the work done by Professor Nabil Nasr in the USA to develop the evidence base for Value Retention Processes, including remanufacturing.
