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.

After several years of fraught negotiations, 98 Member States of the UN agreed on 20 June 2025 to set up a new Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution. The official acronym is ISP-CWP, to sit alongside the existing Intergovernmental Science-Policy Panels on climate heating IPCC and biodiversity IPBES. This is excellent news, but much of the detail was left to the first plenary session, now set for 2-6 February 2026. Much further work is needed, both to ensure that the new Panel has teeth, and that waste is a core part of its ongoing programme.

I am pleased that the RICS Land Journal has published online an updated version of my article on the untapped potential for the waste and resource management sector to act as an enabler to unlock significant climate mitigation benefits across the economy. My best estimate of the mitigation potential is at least 15-20% of global carbon dioxide (equivalent) emissions, which is far beyond the IPCC’s estimate of 3% for the narrowly defined end-of-the linear-economy ‘waste’ sector, which is necessarily used in official climate reporting to avoid double counting.
This post supercedes that titled ‘COP26 and the waste and resource sector’, first published on 25 October 2022:
How much can better waste and resource management contribute to mitigating global heating? Prof David C Wilson addressed this question at the Policy Connect Sustainable Resource Forum seminar on October 11 2021. The answer with a high level of confidence is ‘significantly’, perhaps 15-20% of global carbon dioxide (equivalent) emissions. DCW has now written this up as a ‘thought piece’, making the case for prioritising actions at COP26 and beyond to improve waste and resource management and move towards the circular economy. This may be found as both an article and as a video interview on WasteAid’s COP26 online hub; as a feature on CIWM’s Circular Online; and as an ISWA guest blog.

Language matters. DCW’s March column for the CIWM Journal celebrates the dramatic improvements in waste and resource management that have been achieved since he first entered the sector in 1974. This is largely due to changes in public behaviour, which have enabled the UK, for example, to increase recycling rates over the last 20 years from just 6% to 46%. However, he questions how we can expect people’s mind set to change permanently when some local authorities, and both professionals and politicians, continue to refer to modern recycling facilities as ‘the rubbish tip’.
