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 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.

Professor David C Wilson welcomes the only waste-related official side event at COP26 which is being held in Glasgow today at 1315 and available to watch on the United Nations – Climate Change COP 26 YouTube channel. That the topic is ‘A wasted opportunity: open burning of waste causes a climate and health calamity’ is an added bonus. Congratulations to ISWA, Wasteaid, Engineering X and partners for getting both waste and open burning on the official COP26 agenda!
To ‘eliminate uncontrolled disposal and open burning of waste’ is the second of the waste-related SDGs set out in UNEP and ISWA’s inaugural Global Waste Management Outlook (2015), for which DCW was the lead author. It is one of the two indicators within SDG indicator 11.6.1, for which UN-Habitat have recently published guidance. The climate heating implications of black carbon from open burning of waste have been demonstrated by Natalia Reyna, DCW and co-authors, who estimated that it is responsible for between 2-10% of global CO₂ equivalent emissions. The serious health impacts of open burning have been highlighted in a recent report by Engineering X, who are now leading an international collaboration to support its phasing out – DCW has joined their Technical Advisory Group. Open burning is also a major campaign issue for the charities Wasteaid, of which DCW is a Patron, and Tearfund, to whom DCW has provided advice on their ‘burning issue’ report.

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.’

DCW gives his final speech as CIWM President
The Gaelic Football team which Enda Kiernan manages appeared in the lead photo story of the previous day’s Irish Times
Professor David C Wilson handed over the Presidency of CIWM, the UK and Irish professional body for resources and waste, to Enda Kiernan at the Aviva Stadium in Dublin on 13 November 2018. He highlighted plastics – both plastics entering the oceans and China’s ban on imports for recycling – as the dominant topic in his Presidential year. The public focus on marine plastics also helped dissemination of his Presidential report, the CIWM-Wasteaid Toolkit Making Waste Work; the website clocked 56,000 visits in its first year, with 7,000 downloads. DCW introduced his fellow Irishman, Enda Kiernan of Cork County Council as the next President. CIWM waited more than a century for its first Irish President; now we have had three in five years, and two in a row, although Enda is the first from the Republic of Ireland.
