“…Nevertheless, the rising rate of urbanisation and scarcity in urban land space, coupled with rising MSW generation rates and increasing biodegradable and recyclable waste streams [15][16][17], are triggering a new and growing interest amongst researchers, policymakers, and funding institutions to work together towards the attainment of functional solid waste management (SWM) systems in developing countries [18], with a particular emphasis on waste diversion from landfills. Those charged with MSWM have a new impetus to divert decision making towards the separation of MSW at the source for environmentally friendly valorisation and recycling purposes [8,19,20].…”

This article uses a modified model of the theory of planned behaviour to assess salient beliefs of household heads towards the separation of municipal solid waste at its source in the Greater Accra Region of Ghana. Structural equation modelling was used to analyse the responses of 598 household heads to a questionnaire in a cross-sectional design. Whilst the default model produced an acceptable fit to the data and explained 37% of the variance in households’ intention to separate waste at its source, the modified model with moral norms as an additional construct fitted the data excellently, explaining 52% of the variance in intention. Moral norms and perceived behavioural control were the predominant latent constructs to influence intentions. Control beliefs related to the availability of waste receptacles, provision of regular waste collection services, and access to knowledge of the separation process had the greatest tendency to facilitate households’ intentions. Pro-environmental interventions designed in a participatory manner to promote moral correctness, responsibility, respect for the environment, and positive affect may empower households to separate waste at its source. This research contributes to the development of a municipal solid waste strategy in the region, and may further support research in waste diversion and the circular economy in other jurisdictions.

“…Social marketing scholars acknowledge that a vacuum exists within the consumer-oriented co-design and co-production literature and practice (Dietrich et al, 2016). Practitioners can collaborate with the target audience and stakeholders to co-create (co-design and co-produce) an ideal marketing mix (product, price, place or distribution channels, and communication mix) that will facilitate or increase the uptake of desired behaviour (Chammas et al, 2020;Christie and Waller, 2019;Dietrich et al, 2017b;Domegan et al, 2013;Kim et al, 2020b;Trischler et al, 2019).…”

Influencing household-level waste-sorting and composting behaviour: What works? A systematic review (1995–2020) of waste management interventions

Decentralized waste sorting and composting can divert almost two-thirds of household waste from landfill. However, national rates of composting and recycling remain low in many parts of the globe. This review critically evaluates the design and efficacy of behaviour-change interventions to influence households to sort and compost organic waste. The systematic literature search yielded 3595 titles and abstracts which were reviewed and resulted in 14 unique interventions. The social marketing benchmark criteria are utilized to critically examine the design of these interventions. Synthesized results indicate a need for customized interventions that are co-designed with users and tailored to address their specific needs and challenges. Interventions with four or more social marketing elements produced positive behavioural outcomes, albeit with varying impact. This review highlights gaps in the design of waste management interventions and provides suggestions for future practices.

“…The participants were asked to self-report the frequency of occurrence of symptoms and diseases associated with solid waste malpractices (Table S8: Health Assessment Summary). The methodology to collect the health data was based on an air pollution model, described in [24]. The model simulated the exposure to NOx concentrations (used as representative of landfill gas emission) and the results were presented as percentages from the maximum modeled concentration at the Naameh landfill.…”

“…The work was initiated by six municipalities in Aley District in the aftermath of the closure of the regional landfill of Naameh in 2015, which led to a national solid waste crisis that spanned till 2016 (Waste Crisis 2015-2016 [10]). The municipalities reached out to the American University of Beirut (AUB) for support in assessing the environmental (air, water, and health) damages from waste disposal and improve their waste management practices [24]. In particular, their interest stemmed from a public health scare that emerged from the long-awaited closure of the landfill after years of operation beyond its design capacity.…”

Lebanon is affected by a protracted environmental and solid waste crisis that is threatening the water resources and the public health of its communities. This study is part of a public participatory research project that aims to evaluate the impacts of solid waste disposal practices on water, air, and health in six villages of Lebanon, stigmatized by the presence of a regional landfill. Community mapping enabled the selection and testing of seven springs and three wells in the upstream basin and 11 wells in the lower basin, covering a broad list of chemical, physical, and bacteriological parameters. Two water quality indices (WQ-1 and WQ-2) were used to assess water quality in the study area. The results for the upstream wells and springs showed a significant bacteriological contamination, while the results in the lower wells showed high levels of conductivity, chlorides, and zinc along with the occurrence of organic micropollutants in trace concentrations. The comparison between the experimental data, with the natural background value established in the same area, did not show major differences, except for zinc and bacteriological indicators. The bacteriological contamination is most likely related to sewage infiltration into groundwater at the time of the assessment. Zinc may result from landfill leachate infiltration but also well corrosion. Saltwater intrusion affecting the coastal basin is masking the results for conductivity, chlorides, and sulfates, whereas the presence of small traces of organic micropollutants in the coastal aquifer may be related to leachate infiltration. WQI-1 results, which included bacteriological indicators, showed highly degraded water quality in the C1-C3 inner basin. In contrast, WQI-2, which includes physio-chemical indicators only, showed good water quality, slightly deteriorating in the coastal area, downstream of the Naameh landfill.
