According to the UNEP and ISWA’s Global Waste Management Outlook (GWMO), three billion people lack access to basic solid waste management (SWM) services; addressing this global waste crisis 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 aims to help local communities in the poorest countries, where the local authority often has no funds to provide a SWM service, to tackle the problem themselves through the resource value in the wastes. If, for example, food wastes or low-value plastics are kept separate, they can be turned into new, useful products. With simple tools and the right knowledge, people can become self-employed recycling entrepreneurs, providing a very valuable service for the health and wellbeing of their community, and the whole planet – as well as reducing poverty and creating sustainable livelihoods.
One of the gaps identified by the GWMO was for practical guidance on such low-cost ‘waste to wealth’ technologies which involve minimal capital investment and make products to sell in a local market. DCW’s CIWM Presidential Report aimed to plug that gap: Wasteaid prepared a Toolkit, including a dozen How-to-do-it Guides for simple technologies using organics and low-value plastics.
While preparing the Toolkit, we identified a parallel requirement, for the scientific underpinning of some of the technologies. This month sees the publication of a paper on optimising the technology for producing plastic bonded sand blocks, for use e.g. as paving slabs, from the low value LDPE film plastic, which is a major problem even in the least-developed countries. Our team at Imperial College London was led by Professor Chris Cheeseman, with the laboratory research carried out by Alexander Kumi-Larbi Jnr and Danladi Yunana. The technology was developed by another co-authors, Pierre Kamsouloum, a self-taught entrepreneur from the Cameroun.
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.
China’s recent import ban has thrown Western recycling systems into disarray. DCW has participated as CIWM President in three regional open meetings to address the ‘China recycling crisis’. His April column for the CIWM Journal has written up his presentation, providing a personal perspective on how he has seen China’s internal resource and waste management systems develop over the last 40 years. Arguably, its 1970s system could be viewed as an early example of a circular economy. The transition to ‘market -oriented’ operations led to economic growth being prioritised over environmental protection. But the current ‘National Sword’ campaign is just one symptom of a fundamental change, suggesting that, going forward, perhaps China really could lead the world in transitioning to a circular economy.
DCW’s February column for the CIWM Journal focused on the topical subject of marine plastics. He reported back on ‘Oceans 21’, the latest Development Finance Forum organised by the German Development Bank KfW, where he led a workshop on marine litter. The conclusions were clear: the amount of plastics entering the oceans is at least an order of magnitude greater than estimates of the visible quantities in the oceans or on beaches – so the first priority is to ‘turn off the tap’. And the most effective way to do that is to extend municipal solid waste collection in developing countries to all people and to eliminate uncontrolled dumping and burning; our best judgement was that this could reduce the weight of plastics entering the oceans by 50-70%.
In his first monthly column in the CIWM Journal as CIWM President, Professor David C. Wilson has revisited his Presidential address. His overall theme for the year is solid waste management as a key utility service, underpinning modern society. Within that three strands are to avoid complacency when it comes to protecting public health and the environment; the continuing move from the linear ‘make – use – dispose’ model to a more circular economy; and the global waste crisis, with more than 3 billion people lacking access to a basic solid waste management service.
DCW writes: ‘“Let us work together to promote the fact that solid waste management is one of the essential utility services underpinning our society. Let us ensure that the regular, daily delivery of that service to protect public health and the environment is not undermined, either by on-going cuts in local authority spending or by deregulation following Brexit”. And again: “It is simply unacceptable that 40% of the World’s population lack this basic utility service that we take for granted. We need to ensure that waste collection is extended to all people, and that uncontrolled dumping and open burning is eliminated.”
