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 The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.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

Tackling the global waste crisis through community waste management

Three billion people lack access to basic solid waste management services; addressing this problem would not only vastly improve their lives but also halve the weight of plastics entering the oceans. Professor David C Wilson and Mike Webster of Wasteaid made the case earlier this year, in an open access editorial in the ISWA journal Waste Management & Research, for community waste management as a ‘bottom up’ approach, to run in parallel to traditional ‘top-down’ approaches led by donors and governments. Community waste management requires building capacity at the local level. This is underpinned both by practical guidance, provided by the 2017 CIWM-Wasteaid Toolkit Making Waste Work; and by scientific understanding of the simple technologies in the toolkit. With our colleagues at Imperial College London, we have this month published a paper on optimising the technology for producing plastic bonded sand blocks from the low value LDPE film plastic, which is a major problem even in the least-developed countries.

Charge! – Paying for household waste services

CIWM President and lifelong waste policy and planning consultant David C Wilson reflects in his September column for the CIWM Journal on the challenges of devising the right policies to charge households for solid waste management services. Of course, we already pay for our solid waste services, but that charge is usually hidden within a wider charge or tax, which in the UK is council tax. Across Europe, many local authorities have been experimenting over the last 20 years with pay-as-you-throw (PAYT) systems, where the charge varies at least in part according to usage. The growing evidence base suggests that PAYT does work, in terms of reducing waste quantities and increasing recycling. But why should local authorities, and ultimately households, pay for all the costs of municipal solid waste management? Particularly in the context of Defra’s forthcoming Resources and Waste Strategy for England, DCW argues for real Extended Producer Responsibility (EPR), with teeth, that will move the full financial burden of collecting, recycling and disposing of packaging and other products in the municipal waste stream from local authorities to the producers and supply chain. If we cannot have PAYT, let us at least have PAYB (pay-as-you-buy).

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.
