Waste and resource management on COP29 agenda as a priority climate issue

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.

DCW’s magnum opus wins ISWA Publication Award 2024

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.

GWMO2 now published!

GWMO2 now published!

As lead author of UNEP and ISWA’s original Global Waste Management Outlook (GWMO) in 2015, and a contributing author to the long-awaited follow-up, I am thrilled to welcome the publication at UNEA-6 this week of GWMO 2024: Beyond an age of waste – Turning rubbish into a resource. Warm congratulations to the lead author, Zoë Lenkiewicz, who has written a concise and engaging report which will hopefully succeed in placing municipal solid waste management firmly where it belongs on the local and international political agenda.

Zoe has summed it up brilliantly in the 300 character summary on the back cover of the easy-to-skim-read 80-page report: ‘The Global Waste Management Outlook 2024 echoes the 2015 Global Waste Management Outlook’s call to action to scale up efforts to prevent waste generation; to extend adequate, safe and affordable municipal solid waste management to everyone worldwide; and to ensure that all unavoidable waste is managed safely.’ My thanks and congratulations to the patient project managers, Daniel Ternald of UNEP and Aditi Ramola of ISWA.

Diving Deep: deploying finance to prevent plastic pollution of the oceans

A key constraint to improving waste and resource management in many countries is a lack of access to investment finance. Extending waste collection to all and phasing out uncontrolled dumping and open burning in low-income countries would significantly cut the mass of plastics reaching the ocean. So the UNEP Finance Initiative publication Diving Deep, aimed at banks, insurers and institutional investors, is very welcome. Guidance is provided in the form of a science-based, actionable toolkit, to ensure that their investments, both in product manufacture and in waste management, encourage waste prevention and sound waste management, thus keeping plastics out of the oceans.

The promotional video and the document itself are worth looking at just for the wonderful images by world-renowned photographer Cristina Mittermeier of Sea Legacy. The guidance was prepared by WWF (led by Paula Chin) and RWA (led by Andy Whiteman). DCW played a small role as one of the reviewers.

Make phasing out open burning of waste an international priority

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.
