“…The highest LHV was observed in samples with high plastic content. This is also higher than the mass MSW heating values observed in previous studies (Table 2) at 14.8-16.6 [50] and 18.4-22.9 MJ/kg [51] in Ghana, comparable to that of coal, 18-36 MJ•kg/4500-8500 kcal/kg [34] and higher than that of RDF samples from other studies in Figure 6. However, it is possible to decrease the moisture Energies 2023, 16, 200 9 of 15 in the RDF through pre-treatment such as bio-drying in an integrated system to increase the heating value.…”

Reuse and recycling are preferred strategies in waste management to ensure the high position of waste resources in the waste management hierarchy. However, challenges are still pronounced in many developing countries, where disposal as a final solution is prevalent, particularly for municipal solid waste. On the other hand, refuse-derived fuel as a means of energy recovery provides a sustainable option for managing mixed, contaminated and residual municipal solid waste (MSW). This study provides one of the earliest assessments of refuse-derived fuel (RDF) from MSW in Ghana through a case study in the cities of Accra and Kumasi. The residual/reject fractions (RFs) of MSW material recovery were characterized for thermochemical energy purposes. The studied materials had the potential to be used as RDF. The combustible portions from the residual fractions formed good alternative fuel, RDF, under the class I, II-III classification of the EN 15359:2011 standards. The RDF from only combustible mixed materials such as plastics, paper and wood recorded a significant increase in the lower heating value (28.66–30.24 MJ/kg) to the mass RF, with the presence of organics (19.73 to 23.75 MJ/kg). The chlorine and heavy metal content met the limits set by various standards. An annual RDF production of 12 to 57 kilotons is possible from the two cities. This can offset 10–30% of the present industrial coal consumption, to about 180 kiloton/yr CO2 eq emissions and a net cost saving of USD 8.7 million per year. The market for RDF as an industrial alternative fuel is developing in Ghana and similar jurisdictions in this context. Therefore, this study provides insights into the potential for RDF in integrated waste management system implementation for socioeconomic and environmental benefits. This supports efforts towards achieving the Sustainable Development Goals (SDGs) and a circular economy.

“…We considered the progress of these technologies in their development and the availability of data on them within the context of Ghana. Furthermore, in accordance with the literature [34,41,42], the physical and chemical characteristics of Ghana's municipal solid waste (MSW) enable the implementation of the aforementioned waste-to-energy (WtE) conversion procedures.…”

Ghana is currently facing a waste crisis that presents considerable risks to its environment, economy, and public health. This investigation evaluates four prospective waste-to-energy options—namely, incineration, anaerobic digestion, gasification, and landfill gas—with the objective of mapping out a sustainable strategy for efficient waste management. Among these solutions, anaerobic digestion stands out as a superior option, offering renewable energy production, valuable bio-product creation, and a comparatively lower greenhouse gas emission effect. A cost analysis further reveals that utilizing biogas from anaerobic digestion is not only environmentally friendly but also economically more viable than relying on light crude oil. Producing 200 MW of energy using biogas costs 36% less, potentially resulting in monthly savings of USD 5.46 million for Ghana. However, several obstacles impede the development of WtE. Inaccurate waste data and a lack of clear policies on waste-to-energy hinder the harnessing of Ghana’s WtE potential. To address this, the study recommends (1) implementing a well-defined national strategy complete with regulations and incentives to attract investments and (2) conducting specialized research to optimize WtE technologies for Ghana’s unique waste composition and context. By surmounting these challenges, Ghana stands poised to secure a sustainable future, simultaneously meeting the targets of Sustainable Development Goals 7 and 11. This entails ensuring access to affordable, reliable, sustainable, and modern energy for all (SDG 7) and fostering inclusive, safe, resilient, and sustainable cities and human settlements (SDG 11).

“…The authors highlighted that Kumasi had a higher potential for biogas generation between 2020 and 2022 than Accra. Addae et al [ 101 ] showed substantial biogas and methane production from food waste in Kumasi and the quality and amount of the biogas generated from food waste are superior. The organic waste created in metropolitan areas could be used to produce biogas, a cheap and environmentally friendly means of dealing with waste efficiently [ 102 ].…”
