“…The energy recovery potentials for the main WtE technologies were determined using the equations shown below for incineration, AD, gasification, and landfill gas [22,29,64]. The lower calorific values (LCVs) were taken from a previous publication [26] and are shown in Table 3.…”

Mitigating climate change to limit the global temperature increase (relative to pre-industrial temperatures) to 2 °C is receiving considerable attention around the world. Here, historical and future carbon dioxide equivalent (CO2e) emissions from municipal solid waste (MSW) in Bahrain were calculated using the revised Intergovernmental Panel on Climate Change (IPCC) 1996 and IPCC 2006 methods. The extent to which waste-to-energy (WtE) technologies can contribute to climate change mitigation was assessed by performing a multicriteria analysis. The results indicated that CO2e emissions from MSW in Bahrain have been increasing since the Askar landfill was constructed in 1986. Emission recalculations indicated that CO2e emissions from MSW contribute 6.2% of total emissions in Bahrain rather than the 11.6% reported in the second national communication. Methane emissions from MSW in 2030 are predicted to be 22–63 Gg. The WtE technologies anaerobic digestion and landfill gas recovery gave the best and gasification the worst multicriteria analysis model results. A database of WtE plants around the world should be compiled to allow decisions around the world to be based on best practices. The potential for maximizing energy recovery and decreasing costs needs to be investigated to allow WtE plants to compete better with renewable and nonrenewable energy sources.

“…So could be an electricity generation source. [56] researched the electricity potential from the University of Malaya biodegradable waste generation reported feasibility. However, improvement in waste composition from changes and efficient implementation of waste policies, which include incentives that could change unsustainable waste associated habits are critical for the growth of WtE in developing countries.…”

Waste is an indispensable by-product of most human daily activity. Prevailing waste management strategy, especially in developing countries such as Nigeria, is far below standard, resulting in environmental contamination and pollution which hampers sustainability. This forms the crux of the research paper which entails ascertaining how Waste-to-Energy can serve as a circular economy tool towards climate mitigation that will ensure environmental sustainability. Key challenges relate to moving beyond the perception of ‘waste as a problem’ to ‘waste as a resource’. Ultimately, both waste prevention, as well as a widespread growth in circular economy activities, will require a coherent and holistic approach that takes recovery options into account at every stage of the product life cycle. To achieve this, the study explored the potentials inherent in Waste-to-Energy (WtE) as a tool. The work is qualitative and involves a synchronic evaluation of previous research works relevant to the study to ascertain the viability of WtE as a circular economic tool for scaling back adverse environmental impact. Integration of results with detailed clarifications of circular economy and climate mitigation indicates WtE as an index of sustainable development. The bottom ash from combustion operations serves as feedstock to the construction industry, hence closing a potential pollution loop. Therefore, Waste-to-Energy is ascertained a viable tool that supports the circular economy while coupling with progressive externalities of climate mitigation. Thus, the study recommends that WtE as a tool should be duly considered as a key feature of climate change policy in developing countries, especially in Nigeria.

“…Likewise, the work carried out by Sánchez [16] was identified, in which the recovery of energy through incineration process of the MSW disposed in Doña Juana landfill in the city of Bogotá D.C. was analyzed, using system dynamics as a modeling technique for different proposed scenarios. Finally, Alzate et al [17] evaluated the feasibility of energy recovery projects in Colombia from different technologies applying the tax benefits established in current legislation.…”

The purpose of this study is to determine the financial feasibility of electricity production projects in Colombia using thermal treatment technologies for Municipal Solid Waste (MSW), by assessing the generation potential, the costs associated with investment, operation and maintenance of infrastructure, and the environmental impacts in terms of CO2 emissions. The study is developed for three capital cities that reflect different conditions of production and characteristics of the MSW, which are: Bogotá D.C., Cartagena and Manizales. MSW production volumes were determined from information reported by public sanitation service providers, while their lower calorific value was estimated from a predictive model referenced in the literature. The results of the study indicate that the development of these technologies, in the three cities mentioned, would allow to contribute 2.309 GWh/year, corresponding to approximately 3,3% of the electricity demand in Colombia; likewise, they would reduce CO2 emissions by more than 3 million tons per year, compared to the emissions generated by the final disposal of waste in sanitary landfills. The plant located in the city of Bogota would have the best financial performance, with an internal rate of return of 7,1%, while the infrastructure located in the cities of Cartagena and Manizales would not have an interesting financial performance; under the assumptions raised in the study.
