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 The paper uses previously unpublished results from the Wasteaware database to compare Kigali’s performance with four other East African capital cities – Dar-es-Salaam, Kampala, Nairobi and Maputo.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

DCW hands over his CIWM Presidential Medal for 2018 to Mike Webster
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.
‘Being able to award the President’s Medal is one of the perks of being President, and indeed the only thing that is expected of you after you hand over the chain…. The standard advice is to give it to someone who has particularly helped in my career or in my Presidential year.
I started out in 1974, so my early influencers are now either quite old or have already moved on to the great Circular Economy in the sky.
Looking back on my career, one of the aspects I take most pride in is the number of (then) young people whom I have either brought into the resource and waste sector, or to whose development I have made some contribution; and who I hope won’t be offended if I refer to them, tongue in cheek as, at least in part, my “protégées”.
I am also aware that, in the twilight of my own career, I am leaving behind much unfinished business. So, my thoughts here have gone to one of those protégées, whom I believe can take forward, and make a difference in, an area that is close to my heart. I devoted at least 20 years of my life to working with international organisations, national governments and large cities to develop integrated and sustainable waste management systems.
I have recently drawn attention to the global waste crisis, the more than 3 billion people worldwide who still lack access to basic solid waste management services, which reinforces the comparative failure of such top down approaches; yes, we have made some progress, but it is painfully slow, and corruption often impedes progress. So, I have come to the realisation that, in parallel, we also need to work from the bottom up.
This person is already making an impact, by opening-up opportunities for you and me, as individual resource and waste management professionals and as companies, to get involved and to make a real difference by helping local communities in some of the poorest countries to help themselves by making products to sell locally from the low value organics and plastics in the waste – thus helping to solve their local waste problems, keeping plastics out of the oceans AND giving themselves sustainable livelihoods to feed and educate their families.
This person has done this at considerable personal sacrifice, giving up a secure job to set up a new charity, initially drawing little or no salary while their children were still very young. The charity is now taking off, helped in part by the success of the CIWM-sponsored Toolkit; income has doubled this year, and looks set to triple that figure next year to more than a quarter of a million pounds.
The winner the 2018 CIWM President’s medal is Mike Webster, the Founder and CEO of our sector’s very own charity, Wasteaid.’

DCW’s Presidential year at CIWM continues to be dominated by marine plastics. As part of our efforts to influence developing UK policy in this area, CIWM and Wasteaid published a report: ‘FROM THE LAND TO THE SEA: How better solid waste management can improve the lives of the world’s poorest and halve the quantity of plastic entering the oceans’. His June CIWM column reports success: the day before the biennial Commonwealth Heads of Government Meeting in London in April, Theresa May announced a new Commonwealth Clean Oceans Alliance (CCOA) backed by a £61.4 million funding package of funding to help tackle marine plastics, of which more than £20 million would help developing country members of the CCOA improve waste management at a national and city level.

Europe and North America have a problem with sustainable recycling. China’s ban on imports has thrown the problem into sharp focus: where are the markets for the materials we are collecting for recycling to meet the targets? And how do local authorities balance their already curtailed budgets as prices for recycled materials plummet? DCW’s May CIWM column explores the history of recycling over the last 40 years, and concludes that our existing policy support measures, focusing on increasing supply rather than demand, are not fit for purpose. He argues that we need to rethink recycling to make it a sustainable foundation for our future circular economy; and makes the case for considering explicitly the embodied social, environmental and technical values alongside the market price.
DCW has for the last three years chaired the Steering Committee for an interdisciplinary research project at the University of Leeds, funded jointly by the Natural Environment and Economic and Social Research Councils, to develop a new analytical framework which considers all four of these dimensions of value. The new CVORR (Complex Value Optimisation for Resource Recovery) tool should facilitate future work in this area.
What sort of solutions are suggested by applying complex value thinking? Current approaches focus on increasing the technical value of the recycled materials, for example through separation at source of individual streams rather than co-mingled materials. They also place the risk of fluctuating prices squarely on local authorities and their contractors; and they in turn plead for Government support for new recycling capacity within the UK. But even with support, such facilities need to compete in a global market, and many UK reprocessing companies have failed over the last decade. The obvious place to look for answers is the companies who place on the market the products which become waste, particularly single trip packaging. The complex value framework would suggest that a fundamental rethink of existing systems for EPR (extended producer responsibility) is required. Producers need to meet all costs for collection, sorting and recycling of their products when they become wastes; and to ensure that markets exist for the recycled materials, for example by taking an ownership stake in the reprocessing facilities and using a minimum % of those recycled materials in their products.

To qualify for inclusion in the official (IPCC) inventory of greenhouse gases (GHGs), data for an emission source must meet a quality threshold. This currently excludes black carbon emissions from the open burning of wastes. The relative quantities may be small compared to carbon dioxide from fossil fuels or methane from landfill, but black carbon is around 2,000 more powerful than CO₂ as a GHG and has an even shorter half-life than methane. In the absence of real data, early modelling studies using broad assumptions suggested that black carbon from open burning contributes 5% of total global GHG emissions, causing 270,000 premature deaths a year. DCW’s PhD student at Imperial College London, Natalia Reyna, has been working for the last four years to provide real data which would meet the IPCC requirements. Our first paper, published this month in the leading journal Environmental Research, presents field data from Mexico on how much solid wastes are disposed of by open burning, either by households or at uncontrolled dumpsites. The results suggest a GHG contribution from uncontrolled burning in backyards in Mexico fifteen times larger compared to methane released from the decomposition of equivalent amounts of waste in a disposal site. This suggests that urgent action is needed to reduce domestic open burning of waste and that this would have a significant impact, both on improving local air quality and respiratory health, and on reducing climate change. A future paper will present data on emission factors, i.e. how much black carbon is produced by burning a kilogram of waste.
