Prof David C Wilson took part in a panel discussion at the RWM with CIWM exhibition and conference at the NEC in Birmingham this week. He made the point that while we already know what needs to be done to extend municipal solid waste management services to the unserved half of the World’s population, the UN sustainable development goals (SDGs) are critical to unlocking the political will to make it happen.
Extending waste collection to everyone and eliminating open dumping and burning would specifically address targets under SDGs 11 (sustainable cities), 12 (responsible consumption and production) and 6 (clean water and sanitation). But it would also halve the quantities of plastics reaching the oceans (SDG14 life below water) and contribute to climate mitigation (SDG13) and public health (SDG3). Local recycling would also contribute significantly to SDG8 (livelihoods) and SDG1 (end poverty).
DCW is currently drafting a chapter on SDGs as a driver for change, for an upcoming Routledge Handbook on the circular economy.
Black carbon (BC) emissions from the open burning of municipal solid wastes (MSW) and other waste types contribute significantly to global heating but are not yet included in the official (IPCC) inventory of greenhouse gases (GHGs) due to poor data availability. Natalia Reyna has just completed her PhD thesis at Imperial College London, co-supervised by Professors David C Wilson and Stephen R. Smith, with the aim of generating reliable data to plug that gap. Our second and final paper was published last week in the leading journal Atmospheric Environment, providing a reliable methodology for measuring emission factors (EFs) for black carbon from waste burning. i.e. how much black carbon is produced by burning a kilogram of waste. The two papers have been submitted as evidence to the IPCC sixth assessment study due to be published in 2021.
When the measured emission factors are combined with our earlier measurements of the extent of open burning of municipal solid wastes in Mexico; other published estimates of waste composition and activity levels around the world; and a range of estimates of the global warming potential of black carbon as compared to CO₂; our best estimate of the contribution of BC from the open burning of MSW to global heating is in the range 2-10% of global CO₂Eq emissions. Given the associated air pollution and health impacts, urgent global action is essential to eliminate open burning of waste; this will provide a relatively ‘quick win’ in tackling the global climate emergency.
A short article reporting this research appeared in the September/October 2019 issue of CIWM’s new, award-winning magazine Circular.
Professor David C Wilson has been working for the last two years with the Rwandan academic Telesphore Kabera to apply the Wasteaware indicators to benchmark performance of the solid waste management (SWM) and recycling system in Kigali, the capital of Rwanda. Their results form the basis of a paper published today in the first ever open access issue of the long established ISWA peer-reviewed journal Waste Management & Research. The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.
The Wasteaware benchmark indicators grew out of work originally carried out for UN-Habitat’s Soild Waste Management in the World’s Cities (2010). They provide a standardised method to characterise the performance of a city’s SWM and recycling system across some 15 indicators, some quantitative and some qualitative, covering both waste generation, the physical aspects of waste and resource management, and various governance aspects. Results for the first 40 cities were used extensively in UNEP and ISWA’s inaugural Global Waste Management Outlook (2015). They are now being applied widely, both to characterise the baseline position in a city; to identify priority areas for improvement; and to monitor progress over time.
From this paper on East Africa, the stand-out result is the relatively high collection coverage achieved in two of the cities: in Maputo with extensive international technical assistance, and in Kigali using its own local resources. In both cases, governance factors are key. Kigali uses a public-private partnership (PPP), with exclusive franchises in 35 sectors being tendered every three years; households pay an affordable fee depending on their ability to pay (the service is free to the poorest category); 95% fee collection rates are achieved, partly through co-collection with charges for local security patrols, which is a service people value highly given the recent history of the country.
Another key priority to improve solid waste management across East Africa is to eliminate open dumping – only Kampala currently has an engineered disposal site. Recycling rates also need to be increased – only Nairobi currently has a good baseline to build on (30%). Common weaknesses include a lack of segregation at source; and of institutional capacity and of available and reliable waste data.
Professor David C. Wilson’s final contribution to the CIWM Journal took the form of an interview in which he looked back on his Presidential year. This web-posting also includes an index of and links to his monthly columns for the CIWM journal, many of which were ‘think-pieces’ on issues in which he has been involved for years or even decades. Among the questions covered in the final interview were: has any topic dominated the year (yes, plastics – both marine plastics and the ‘China ban’); and what would be your advice to Enda Kiernan and future CIWM Presidents (‘Be true to yourself’ – which the editor also used as this month’s headline).

Promoting waste reduction and recycling:
- Sep 2018: Charge! DCW reflected on the challenges of devising the right policies to charge households for solid waste management services
- May 2018: Revaluing recycling. DCW argued that we need to rethink recycling if it is to become sustainable and proposed a framework for doing so, by considering the embodied social, environmental and technical values alongside the market price.
- Jan 2018: Inspiring reuse. DCW showcased the five inspiring projects shortlisted for Best Reuse or Waste Prevention Project at the CIWM Sustainability and Resource Awards 2017.
Waste and climate
- Jul 2018: Don’t waste our climate. DCW made the case for resource and waste management as an entry point to achieve significant climate mitigation. The article was subsequently re-published by the National Solid Waste Association of India (NSWAI) in their member journal Waste Monitor in July 2019.
- Website May 2018: Uncontrolled burning of solid waste as a significant contributor to climate change. DCW reported on current research at Imperial College London.
Tackling the global waste crisis

- Website Oct 2018: Tackling the global waste crisis through community waste management. DCW reported on two papers in the peer-reviewed literature, which follow-up on the CIWM-Waste aid toolkit Making Waste Work.
- Dec 2017: A key utility service. A key theme for DCW’s Presidential year was to highlight the global waste crisis, the 3 billion people who lack access to basic SWM services.
- Website Nov 2017: DCW launches toolkit for community waste management. Introducing DCW’s Presidential Report, the CIWM-Wasteaid Toolkit Making Waste Work. The Toolkit includes a dozen How-to-do-it Guides to enable local entrepreneurs to implement simple technologies using organics and low-value plastics in the waste.
Other DCW areas of interest or ‘hobby horses’:
- Aug 2018: Hazardous waste – plus ça change. DCW reflected on 40 years of involvement with hazardous waste policy, and concluded that the current and future challenges identified by CIWM’s Hazardous Waste Special Interest Group have changed relatively little over the years.
- Mar 2018: Let’s skip “the tip”. DCW argued that terms such as “the tip”, “rubbish”, “refuse” and arguably “tipping”, have no place in the vocabulary of the professional waste and resource manager.
DCW hands over his CIWM Presidential Medal for 2018 to Mike Webster
At the CIWM Presidential Dinner at the Intercontinental Hotel in Dublin, after the inauguration of Enda Kiernan as the next President, DCW’s last act as the retiring President was to award his CIWM Presidential Medal for 2018. The recipient was Mike Webster, the founder and CEO of the new charity Wasteaid, which is working directly with local communities in some of the least developed countries to tackle the global waste crisis. The text of DCW’s speech is reproduced below.
‘Being able to award the President’s Medal is one of the perks of being President, and indeed the only thing that is expected of you after you hand over the chain…. The standard advice is to give it to someone who has particularly helped in my career or in my Presidential year.
I started out in 1974, so my early influencers are now either quite old or have already moved on to the great Circular Economy in the sky.
Looking back on my career, one of the aspects I take most pride in is the number of (then) young people whom I have either brought into the resource and waste sector, or to whose development I have made some contribution; and who I hope won’t be offended if I refer to them, tongue in cheek as, at least in part, my “protégées”.
I am also aware that, in the twilight of my own career, I am leaving behind much unfinished business. So, my thoughts here have gone to one of those protégées, whom I believe can take forward, and make a difference in, an area that is close to my heart. I devoted at least 20 years of my life to working with international organisations, national governments and large cities to develop integrated and sustainable waste management systems.
I have recently drawn attention to the global waste crisis, the more than 3 billion people worldwide who still lack access to basic solid waste management services, which reinforces the comparative failure of such top down approaches; yes, we have made some progress, but it is painfully slow, and corruption often impedes progress. So, I have come to the realisation that, in parallel, we also need to work from the bottom up.
This person is already making an impact, by opening-up opportunities for you and me, as individual resource and waste management professionals and as companies, to get involved and to make a real difference by helping local communities in some of the poorest countries to help themselves by making products to sell locally from the low value organics and plastics in the waste – thus helping to solve their local waste problems, keeping plastics out of the oceans AND giving themselves sustainable livelihoods to feed and educate their families.
This person has done this at considerable personal sacrifice, giving up a secure job to set up a new charity, initially drawing little or no salary while their children were still very young. The charity is now taking off, helped in part by the success of the CIWM-sponsored Toolkit; income has doubled this year, and looks set to triple that figure next year to more than a quarter of a million pounds.
The winner the 2018 CIWM President’s medal is Mike Webster, the Founder and CEO of our sector’s very own charity, Wasteaid.’
