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.

In DCW’s new paper with Andy Whiteman and Nicole Hennessy, published open access by the leading journal Oxford Development Studies, we spotlight the urgent need to rethink how to extend waste services to reach underserved communities. UNEP and ISWA’s GWMO2024 estimates that 2.7 billion people worldwide still lack access to solid waste collection, with at a least a billion more whose collected waste is open dumped or burned. Progress in extending services in upper middle income countries and in parts of larger cities in lower income countries has been steady, but too many unserved or underserved communities are proving hard to reach. We argue that it is time for a radical rethink of our approach to tackle this global waste emergency.
The benefits of extending services to underserved communities (i.e. reaching 95+% on both components of indicator SDG 11.6.1. i.e collection coverage and controlled disposal) are Win⁵ (i.e. win-win-win-win-win): better community services, reduced disease outbreaks, more sustainable livelihoods, reduced municipal solid waste quantities and management costs, and reduced local and global environment impacts. The costs are local but the benefits are global and local: extending services to meet SDG11.6.1 would reduce macroplastic dispersal to the environment by ~80% and significantly mitigate climate heating.
Cities can transition earlier to more circular, integrated, sustainable, waste and resource management (WaRM), through initiating governance reforms; making early no regret investments; and focusing on what money matters? No regret investments include extending collection services; supporting recovery value chains – e.g. separating (wet) organic wastes from (dry) recyclable materials at source unlocks markets for both; and upgrading existing designated disposal facilities. A blend of finance is needed, from national and city sources, resource revenues, disposal pricing, extended producer responsibility (EPR) and international development (including climate and plastics) finance). New multi-lateral impact funds are needed that target extension of services to underserved communities.
Thanks to the Oxford Development Studies editors Jo Beall and her co-editor Mansoor Ali for inviting us to contribute to the (in process) Special Issue on Integrated Sustainable (Solid) Waste Management.

Professor David C Wilson is pleased to co-author an important new publication The Nine Development Bands: A conceptual framework and global theory of waste and development. The open access paper in ISWA’s peer-reviewed journal Waste Management & Research can be downloaded freely. The ‘9 DBs’ builds on the integrated sustainable waste management (ISWM) analytical framework to help characterise waste and resources management (WaRM) systems in cities and countries. Based on over 100 years of combined experience of the authors (Andrew Whiteman, Mike Webster and DCW), the 9DBs is a powerful addition to the waste management practitioner’s toolkit, bringing depth and nuance to understanding of WaRM systems globally.
The early DBs reflect stepwise improvement towards the new
baseline of meeting the SDG 11.6.1 indicators of universal collection and
management in controlled facilities (DB5); while later DBs represent two
prevailing routes to move towards environmentally sound management (ESM) and
the 3Rs (Reduce, Reuse, Recycle). An aspirational DB Zero, a real circular
economy, sits above all 9 DBs, accessible via multiple pathways, posing an
ultimate challenge for development practice. The 9DBs contextualise the
challenge of meeting the waste-related SDGs, in particular for developing
countries striving towards SDG 11.6.1 but also for all countries aspiring to a
circular economy. Whether you are a practitioner, decision-maker, service
provider, or sector activist, the 9DBs will help you to identify the key
pressure points for catalysing change, and focus your time and resources on
achieving maximum impact.
