This article assesses the performance of the city of Accra, Ghana, in municipal solid waste management as defined by the integrated sustainable waste management framework. The article reports on a participatory process to socialise the Wasteaware benchmark indicators and apply them to an upgraded set of data and information. The process has engaged 24 key stakeholders for 9 months, to diagram the flow of materials and benchmark three physical components and three governance aspects of the city's municipal solid waste management system. The results indicate that Accra is well below some other lower middle-income cities regarding sustainable modernisation of solid waste services. Collection coverage and capture of 75% and 53%, respectively, are a disappointing result, despite (or perhaps because of) 20 years of formal private sector involvement in service delivery. A total of 62% of municipal solid waste continues to be disposed of in controlled landfills and the reported recycling rate of 5% indicates both a lack of good measurement and a lack of interest in diverting waste from disposal. Drains, illegal dumps and beaches are choked with discarded bottles and plastic packaging. The quality of collection, disposal and recycling score between low and medium on the Wasteaware indicators, and the scores for user inclusivity, financial sustainability and local institutional coherence are low. The analysis suggests that waste and recycling would improve through greater provider inclusivity, especially the recognition and integration of the informal sector, and interventions that respond to user needs for more inclusive decision-making.

Twenty years of formal private sector participation in solid waste management in Ghana has failed to deliver an increase in collection coverage and recycling rates. This article shares lessons and experiences from Accra, Ghana, a middle-income city where researchers and municipal solid waste managers have collaborated to modernize the municipal solid waste management system by working together to develop a locally appropriate response to the informal waste service sector. Stakeholders have used inclusive decision-making and participatory research methods to bring formal service providers to work in partnership with their informal counterparts to improve collection and recycling. The Wasteaware benchmark indicator framework has been used to assess and compare the improvements in the physical and governance aspects of the municipal solid waste management system, supplemented by statistical analysis of responses to a survey on the socio-economic contribution of the informal service providers in the city. Within two years of their inclusion, the number of informal service providers has increased by 71 percent, from 350 to 600, creating new livelihoods and contributing to poverty reduction. The informal service providers have been able to increase collection coverage from 75% to 90%, waste capture from 53% to 90%, and recycling rates from 5% to 18%, saving the municipality US$5,460,000.00 in annual operational costs. The results have influenced the decision-makers to move towards structural integration of the informal service providers into the formal waste service system. The shift towards practical, locally responsive interventions in Accra provides a positive example of sustainable waste management modernization, and key lessons for cities in similar economies.

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.

This chapter addresses three peculiar challenges in the solid waste management system of developing countries, namely: the chronic lack of reliable data for planning purposes, the absence of participatory engagement strategies in data gathering for wider ownership and usage, and the lack of monitoring of the climate change burden of existing waste disposal practices. A team of researchers has collaborated with system managers and a responsible philanthropic organization to engage key stakeholders to address these gaps in a sustainable manner. The strategy deployed has been to work in a participatory and evidenced-based frame to solicit support, enhance capacities, empower each other to understand the problems and find for ourselves the practical routes by which solid waste data gaps can be closed in the greater Accra region of Ghana. Stakeholders have participated in a comprehensive waste audit and landfill emission monitoring exercise to develop a baseline, and have used local resources and ideas to recommend steps to sustain reliable data flows and the development of a climate action plan for purposes of modernization. The methodological processes and research outcomes suggest that structural collaboration between researchers and system stakeholders is necessary to break the vicious circle of chronic data gaps and substitute virtuous circles of reliable data for planning purposes.
