    The University of the Western Cape (UWC) in association with Eunomia Research & Consulting Ltd. (Eunomia) is pleased to announce the findings of a study on the feasibility, cost, and impact of a proposed mandatory single-use beverage Deposit Return System (DRS) for South Africa. The study was co-funded by the Norwegian Embassy and the Alliance to End Plastic Waste (Alliance). The report provides a tailored DRS for single-use beverage packaging designed to meet the needs of South Africa. The report indicates that under such a system, collection rates for beverage containers can increase significantly, particularly for plastic bottles and glass bottles. A deposit level of ZAR 1 could achieve collection rates as high as 90% – higher than South Africa’s existing Extended Producer Responsibility (EPR) targets. An important aspect of this study has been on-the-ground research into key aspects that define the South African context. This involved engaging with the informal economy through waste reclaimer interviews and workshops, as well as surveying Buy Back Centres (BBCs) – which purchase recyclable materials from waste reclaimers and other suppliers – and informal retailers and HORECA establishments. The research undertaken for this study also included a market overview consisting of field surveys and data analysis, and a literature review of South African legislation and DRS/EPR legislation from nations in Africa and beyond. In terms of environmental impact, the DRS is projected to deliver a substantial net reduction in greenhouse gas (GHG) emission, ranging from 119 to 294 thousand tonnes CO2e per year. These reductions are expected on both the low and high placed-on-the-market (PoM) baselines and across two return route scenarios.

    A three-pronged approach to waste composition determination
    (Elsevier, 2022-02-01) Nell, Charlotte; Schenck, Catherina; Blaauw, Derick; Grobler, Lizette; Viljoen, Kotie
    Understanding solid waste composition has frequently been cited as one of the most valuable resources to those responsible for the proper management of solid waste. The unique contribution of this article lies in the fact that a waste characterisation study, conducted in a remote rural town in South Africa, was combined with an illegal dumping contents mapping and a household survey. This enabled researchers to gain a more thorough understanding of household waste management practices and challenges in this community, bridging the knowledge gap that is created when illegal dumping and household perceptions are omitted from waste characterisation studies in study areas where illegal dumping is an ongoing concern. The study therefore contributes to understanding the waste behaviour of households within the larger context of the town's waste management practices. Results indicate that, in order for municipalities to fully understand how to manage their waste, the contents of illegal dumping, where present, and household surveys should also be included in waste characterisation assessments.
