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 The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.
The Wasteaware benchmark indicators grew out of work originally carried out for UN-Habitat’s Soild Waste Management in the World’s Cities (2010). They provide a standardised method to characterise the performance of a city’s SWM and recycling system across some 15 indicators, some quantitative and some qualitative, covering both waste generation, the physical aspects of waste and resource management, and various governance aspects. Results for the first 40 cities were used extensively in UNEP and ISWA’s inaugural Global Waste Management Outlook (2015). They are now being applied widely, both to characterise the baseline position in a city; to identify priority areas for improvement; and to monitor progress over time.

From this paper on East Africa, the stand-out result is the relatively high collection coverage achieved in two of the cities: in Maputo with extensive international technical assistance, and in Kigali using its own local resources. In both cases, governance factors are key. Kigali uses a public-private partnership (PPP), with exclusive franchises in 35 sectors being tendered every three years; households pay an affordable fee depending on their ability to pay (the service is free to the poorest category); 95% fee collection rates are achieved, partly through co-collection with charges for local security patrols, which is a service people value highly given the recent history of the country.

Another key priority to improve solid waste management across East Africa is to eliminate open dumping – only Kampala currently has an engineered disposal site. Recycling rates also need to be increased – only Nairobi currently has a good baseline to build on (30%). Common weaknesses include a lack of segregation at source; and of institutional capacity and of available and reliable waste data.

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).
