2 December, 2024 | Environmental legislation, Waste Management
I am shocked that the 50th anniversary of the first environment control legislation in the 1970s, and specifically the UK’s Control of Pollution Act 1974 (CoPA) has received so little attention and celebration. So I have written a Comment piece on CoPA’s Golden Jubilee for resource.co, one of the leading online news sites read by (UK) waste and resource management professionals.
The waste and resource sector as we know it only exists due to strong and effectively enforced legislation to create a ‘level playing field’, which in principle should enable investment without fear of being undercut by lower standard facilities or indeed by waste criminals. Prior to legislation in the 1970s, the norm for collected wastes was disposal in uncontrolled or partially controlled ‘landfills’ which were often permanently on fire. As I have documented in my recent magnum opus, we have come a long way in 50 years, but we also still have a long way to go. That was illustrated starkly by the announcement in November 2024 of the closure of a UK state-of-the-art plastics recycling facility after just two years.

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.

My 2024 ISWA Publication Award for my ‘magnum opus’ was presented this week at the Gala Dinner at ISWA 2024 World Congress in Capetown. My thanks to Costas Velis for collecting the award on my behalf. The paper documents the evolution of waste and resource management over the last 50 years from my personal perspective as an involved witness, and uses that to reflect on current and future priorities.
In their citation ISWA say: ‘David emphasises the need for understanding and learning from the (past) to achieve improved (waste and resource) management around the world. The paper zooms in on three policy priorities that are critical globally: access to sustainable financing, rethinking sustainable recycling and worldwide extended producer responsibility. (In the Global South this) require(s) a people-centred approach, working with communities to provide both quality services and decent livelihoods for collection and recycling workers.’
The paper could not have been written without the work and support of the countless colleagues I have worked with over my now 50 year career – my warm thanks to you all! I have been motivated in writing this to ‘pass on the baton’ to the next generations – so please do follow ISWA’s endorsement and dip into the open access paper – I hope it gives you some inspiration.
As well as the full paper, I published a ‘taster’ version in March 2024 in the ISWA magazine Waste Management World. I struggled to squeeze 50 years of evolution since the first environmental controls over solid waste management were introduced in the 1970s, and reflections on priorities for the next decade(s), into my 50,000 word (but very accessible and readable!) contemporary witness magnum opus. I had to write a 200 word abstract, but it took me a while to prepare this short (2,500 word) ‘taster’ version. My basic thesis is that policy makers, practitioners and academics need to understand where waste and resource management has come from to plan confidently to meet future challenges and to avoid ‘reinventing the wheel’. So please have a read, pass it on to colleagues and dip into the full paper!
The title of the full paper is: Learning from the past to plan for the future. An historical review of the evolution of waste and resources management 1970-2020 and reflections on priorities 2020-2030 – The perspective of an involved witness.

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.

According to the UNEP and ISWA’s Global Waste Management Outlook (GWMO), three billion people lack access to basic solid waste management (SWM) services; addressing this global waste crisis would not only vastly improve their lives but also halve the weight of plastics entering the oceans. Professor David C Wilson and Mike Webster of Wasteaid made the case earlier this year, in an open access editorial in the ISWA journal Waste Management & Research, for community waste management as a ‘bottom up’ approach, to run in parallel to traditional ‘top-down’ approaches led by donors and governments.
Community waste management aims to help local communities in the poorest countries, where the local authority often has no funds to provide a SWM service, to tackle the problem themselves through the resource value in the wastes. If, for example, food wastes or low-value plastics are kept separate, they can be turned into new, useful products. With simple tools and the right knowledge, people can become self-employed recycling entrepreneurs, providing a very valuable service for the health and wellbeing of their community, and the whole planet – as well as reducing poverty and creating sustainable livelihoods.
One of the gaps identified by the GWMO was for practical guidance on such low-cost ‘waste to wealth’ technologies which involve minimal capital investment and make products to sell in a local market. DCW’s CIWM Presidential Report aimed to plug that gap: Wasteaid prepared a Toolkit, including a dozen How-to-do-it Guides for simple technologies using organics and low-value plastics.
While preparing the Toolkit, we identified a parallel requirement, for the scientific underpinning of some of the technologies. This month sees the publication of a paper on optimising the technology for producing plastic bonded sand blocks, for use e.g. as paving slabs, from the low value LDPE film plastic, which is a major problem even in the least-developed countries. Our team at Imperial College London was led by Professor Chris Cheeseman, with the laboratory research carried out by Alexander Kumi-Larbi Jnr and Danladi Yunana. The technology was developed by another co-authors, Pierre Kamsouloum, a self-taught entrepreneur from the Cameroun.
