WHO is launching a new global report, “Throwing away our health: The impacts of solid waste on human health.” Join the launch webinar on 16 Dec 2025, 13:00–14:00 UTC / GMT. DCW was pleased to advise on and review this important report and will join the panel discussion at the launch.
Formal municipal solid waste (MSW) management services were introduced in 19th century cities to protect public health. This report is a timely reminder of the continuing importance of that role, drawing attention in particular to the continuing public health risks where municipal solid wastes are not collected (UNEP/ISWA GWMO: 2.7 billion people without waste collection) and/or when they are open dumped or burned (~40% of global MSW collected). The report brings together current knowledge on how solid waste can impact health in both the global south and the global north; where the evidence is still missing; and what the health sector can do to drive change.

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.

I have been writing articles and blogs for nearly 10 years to challenge the common misperception that waste and resource management contributes minimally to mitigation of climate heating. At long last, my peer-reviewed paper with ISWA co-authors collating the evidence has now been published open-access. We show that one can have HIGH CONFIDENCE that the sector’s potential is SIGNIFICANT. The paper provides a Call to Action to enable this global opportunity to be realised.
An earlier version of the paper featured at the first ever Waste and Resources pavilion, hosted by ISWA at COP28 in Egypt. This year in Baku, waste and resource management featured for the first time on the main COP29 agenda, with a Declaration On Reducing Methane from Organic Waste endorsed so far by 52 countries. The declaration has 8 objectives, which go beyond a narrow, waste sector focus on mitigating methane from landfill, to include also food waste reduction and separation of organic wastes at source for valorisation and recycling back to the soil.
The declaration highlights five enabling areas for waste sector transformation, calling for all countries to include reducing methane from organic waste in their climate mitigation plans at both national level (Nationally Determined Contributions – NDCs) and in regional and local implementation plans; stepping up finance; data for action and transparency; and innovative partnerships.
It is pleasing that this is already reflected in the Call to Action in our paper. The paper would never have been completed without the help and support of my co-authors, so heartfelt thanks to Johannes Paul, and to ISWA Technical Director Aditi Ramola and President Carlos RV Silva Filho.

China’s recent import ban has thrown Western recycling systems into disarray. DCW has participated as CIWM President in three regional open meetings to address the ‘China recycling crisis’. His April column for the CIWM Journal has written up his presentation, providing a personal perspective on how he has seen China’s internal resource and waste management systems develop over the last 40 years. Arguably, its 1970s system could be viewed as an early example of a circular economy. The transition to ‘market -oriented’ operations led to economic growth being prioritised over environmental protection. But the current ‘National Sword’ campaign is just one symptom of a fundamental change, suggesting that, going forward, perhaps China really could lead the world in transitioning to a circular economy.
