“…Previous studies on waste management either had a scientific focus [21], or economic justifications [22], socio-legal aspects [23,24], or technology advancements and related issues [25], including WtE plants in some European countries [26]. There is also a profound literature on the future of renewable energy and sustainability compiled by Professor Olabi [27e29] with an emphasis being placed on energy security.…”

a b s t r a c tThis paper proposes an overarching review of national municipal waste management systems and wasteto-energy as an important part of it in the context of circular economy in the selected countries in Europe. The growth of population and rising standards of living means that the consumption of goods and energy is increasing. On the one hand, consumption leads to an increase in the generation of waste. On the other hand, the correlation between increased wealth and increased energy consumption is very strong as well. Given that the average heating value of municipal solid waste (MSW) is approximately 10 MJ/kg, it seems logical to use waste as a source of energy. Traditionally, waste-to-energy (WtE) has been associated with incineration. Yet, the term is much broader, embracing various waste treatment processes generating energy (for instance, in the form of electricity and/or heat or producing a wastederived fuel). Turning waste into energy can be one key to a circular economy enabling the value of products, materials, and resources to be maintained on the market for as long as possible, minimising waste and resource use. As the circular economy is at the top of the EU agenda, all Member States of the EU (including the EEA countries) should move away from the old-fashioned disposal of waste to a more intelligent waste treatment encompassing the circular economy approach in their waste policies. Therefore, the article examines how these EU policies are implemented in practice. Given that WtE traditionally is attached to the MSW management and organisation, the focus of this article is twofold. Firstly, it aims to identify the different practices of municipal waste management employed in selected countries and their approaches in embracing the circular economy and, secondly, the extent to which WtE technologies play any role in this context. The following countries, Estonia, Greece, Italy, Latvia, Lithuania, Norway, Poland, Slovenia, Spain, and the UK were chosen to depict a broad European context.

“…After the energy crisis in the 1970s, SW incineration techniques were quickly developed in countries like Japan, Denmark, Sweden, Switzerland, China, Spain, and Austria [9,20]. The great majority of these WTE plants are based on moving grate combustion of as-received or post-recycled MSW, and produce electricity and heat [21].…”

“…During the process, a certain amount of methane and other higher hydrocarbons are generated depending on the design of the reactor and its operating parameters. The resulting synthesis gas can generate electricity with combustion engines, and it is potentially more efficient than the direct combustion of the original fuel because it can be burned at higher temperatures or even in fuel cells [21].…”

Assessment of Government Incentives for Energy from Waste in Colombia

et al. 2018

This work evaluates the prefeasibility of energy from waste projects in Colombia under the guidelines of Law 1715. That piece of legislation proposes tax incentives for non-conventional energy initiatives, such as deductions of up to 50% on the investment through income tax, VAT exemption, tariff exemption, and accelerated depreciation of assets. Pasto, Colombia, was selected as the case study. Subsequently, incineration, gasification, anaerobic digestion, and landfill gas technologies were evaluated. The potential of electric power generation from municipal solid waste (MSW) of each conversion technology was estimated with mathematical models. Additionally, the economic evaluation considered five cases that combine loan options, accelerated depreciation, and income deductions. Finally, the prefeasibility analysis of each case and technology was based on the internal rate of return (IRR) and levelized cost of electricity (LCOE). The results reveal that only anaerobic digestion and landfill gas technologies constitute viable projects in case of traditional investment with and without loans, because they present IRRs greater than the discount rate, of 6.8%. However, by including the incentives in Law 1715 in the economic evaluation, IRRs of 11.18%, 7.96%, 14.27%, and 13.59% were obtained for incineration, gasification, anaerobic digestion, and landfill gas, respectively. These results make all four technologies feasible in this context.

“…From the foregoing, it is an undeniable fact that new and innovative climate change mitigation solutions are needed for public and private actors alike to step up efforts and creativity in identifying mitigation options. Circular economy is one such approach that offers precisely this opportunity, through strategies such as recirculating a larger share of materials, reducing waste in production, light-weighting products and structures, extending the lifetimes of products, and deploying new business models based around sharing of cars, buildings, and more [38]. A circular economy can reduce CO 2 emissions, reduce the scale of the challenge of decarbonising materials production, and contain the cost of achieving an industrial base compatible with a low-carbon economy.…”

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.
