Resource and Waste Management and the SDGs

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. DCW is currently drafting a chapter on SDGs as a driver for change, for an upcoming Routledge Handbook on the circular economy.

Measuring black carbon emissions from open burning of waste

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. 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 climate emergency. The two papers have been submitted as evidence to the IPCC sixth assessment study due to be published in 2021.

Benchmarking performance of SWM systems in East Africa

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 The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.

DCW looks back on his CIWM Presidential year

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).

DCW awards his Presidential Medal

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.

DCW commissioned WasteAid UK to prepare a practical toolkit for poor communities on how to make useful products from the low-value plastics and organics in their waste. In its first year, the website was visited 56,000 times, with 7,000 downloads of the toolkit.
