Proper Waste Management in the Plastics Treaty

I am very pleased to collaborate with Tearfund to reframe the discussion around waste management in the Plastics Treaty negotiations. The Plastics Treaty is once-in-a-generation opportunity to end Plastic Pollution. We absolutely need to ‘turn off the tap’ by upstream actions to reduce plastic production, but we also need to ‘stop the bath-tub overflowing’ through proper waste management.

This is not a ‘cop out’ for the plastics producers – they are responsible for the high plastics content in municipal solid waste in lower income countries, which cannot afford proper management; so it is their responsibility to ensure that their wastes are collected and recycled properly and to pay all of the associated costs. The scientific part of the Tearfund report shows that extending municipal solid waste collection and controlled recovery and disposal to services to all (95% on SDG indicator 11.6.1) would not only address a major public health and environmental crisis impacting billions worldwide, but also reduce macroplastics dispersal to the environment (and thus available for onward transport to the ocean) by 77% and open burning by 90% . So, let’s make sure that is done!

UPDATE. The report puts forward a fit-for-purpose text on waste management for negotiators. The initial report was issued prior to the negotiation meeting INC-4 in Ottawa from 23-29 April 2024. A second edition was issued in September, to provide specific inputs to the final text negotiations which should have been concluded at INC-5 in Busan 25 November – 1 December 2024.

UPDATE. The modelling for this report by Costas Velis, Ed Cook and Josh Cottam of the University of Leeds used their SPOT model. Their seminal paper showing that uncollected municipal solid waste accounts for 85% of uncontrolled macroplastic dispersal to the environment was published in Nature in September 2024.

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.

The significant potential of better waste and resource management for climate mitigation

ISWA are hosting the first ever Waste and Resources Pavilion at COP28 in Dubai. My contribution is an article, co-authored with the ISWA President Carlos Silva Filho and Technical Director Aditi Ramola, where we challenge the common perception that waste and resource management contributes minimally to mitigation of climate heating. We argue that is simply WRONG, and one can have high confidence that the sector’s potential is significant. Whatever the actual number, action is needed now: it is imperative that better waste and resource management is prioritised in climate action plans and nationally determined contributions.

Socio-economic development drives solid waste management performance in cities

Our new open access paper tests and confirms for the first time the long-standing hypothesis that both the rate of municipal solid waste (MSW) generation in a city, and the performance of its MSW management system, depends on its level of socio-economic development level. We prepared the first consistent and comprehensive dataset for 40 cities around the world and used state-of-the-art statistical and machine learning techniques to correlate Wasteaware Cities Benchmark Indicators (WABI) with a broad range of explanatory socio-economic indices (including Gross Domestic Product (GDP), Social Progress Index (SPI) and Corruption Perceptions Index (CPI).

The results indicate that progress in collection coverage, and controlled recovery and disposal, has already taken place in low- and middle-income cities, although improvements in service quality often lag improvements in service coverage. However, the elephant in the room is that if we continue with ‘business as usual’ development, waste generation per capita and the total quantities (and cost) of waste management services will substantially increase. We urgently need to find new approaches to decoupling waste generation from economic growth and social progress.

The paper is open access and can be downloaded free of charge. It has taken a long time in preparation: thanks to my co-authors Costas Velis, Yoni Gavish, Sue M Grimes and Andrew Whiteman.

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.

Nine Development Bands – a new theory of waste and development

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.
