System-wide assessment of Indonesia’s plastic value chain

3 December, 2025 | Waste Management

DCW was pleased to co-author two papers on a system-wide assessment of Indonesia’s plastic value chain. One, mapping external stakeholders, was published this week in the journal Environment Systems and Decisions. The other mapped both plastic and monetary flows and stakeholders dynamics, and was published in July in the high impact Journal of Cleaner Production. A third part of the trilogy was published in the Journal of Circular Economy in April 2025. All three papers demonstrate the innovative use of the structured systems-based framework provided by CVORR (Complex Value Optimisation for Resource Recovery), for the earlier development of which I chaired the Steering Committee. I also sat on the Advisory board of PISCES, a collaborative research project on preventing plastics pollution in Indonesia, from which these papers are outputs.

I am grateful to the two lead authors Eleni Iacovidou and Spyridoula Gerasimidou; and to my fellow co-authors Professor Susan Jobling; Eddy Setiadi Soedjono; Jessika Luth Richter; Mike Webster; Andre Kuncoroyekti; and Elena Lovat.

Forget everything you thought you knew: 10 insights from the frontline of extending waste management services

1 October, 2025 | Publication, Waste and resource management

DCW was delighted to write the Introduction to October’s editorial in the ISWA peer-reviewed journal Waste Management & Research (WM&R), where Mike Webster gives his personal reflections from five years of working to extend waste collection services to previously underserved communities in Indonesia. The world is struggling to deal with the global waste emergency of more than 2.7 billion people worldwide lacking access to the basic service of municipal solid waste collection. Mike’s reflections offer a ‘breath of fresh air’ – using his words to summarise: let’s not forget the basics of solid waste collection and controlled disposal, let’s be clear-eyed about the challenges, and let’s get on with it…

Thank you to the Editors-in-Chief Anke Bockreis, Arne M. Ragossnig and Costas Velis for publishing the editorial this month in the Special Issue of WM&R for the ISWA2025 World Congress in Buenos Aires from October 27-29 2025.
