“…• Topic 3 explores waste management (i.e., food wastes, municipal wastes) mainly through anaerobic digestion as a source of bioenergy (i.e., biogas). Examples include [49] demonstrating that urban waste bio-refining enables resource looping and increases resource efficiency, and [80] providing recommendations for the municipal solid waste (MSW) policy framework and MSW management practices. • Topic 4 addresses instruments for CE implementation (e.g., eco-design and eco-industrial parks) considering mainly the case of China.…”

The debate about Circular Economy (CE) has been increasingly enriched by academics through a vast array of contributions, based on several theoretical perspectives and emanating from several research domains. However, current research still falls short of providing a holistic and broader view of CE, one that combines existing themes and emerging research trends. Accordingly, based on a Systematic Literature Network Analysis, this paper tackles this gap. First, a Citation Network Analysis is used to unearth the development of the CE literature based on papers' references, whilst the Main Path is traced to detect the seminal papers in the field through time. Second, to consider the literature in its broader extent, a Keywords Co-Occurrence Network Analysis is conducted based on papers' keywords, whereby all papers in the dataset, including the non-cited papers, are assessed. Additionally, a Global Citation Score analysis is conducted to uncover the recent breakthrough research, in addition to the Burst Analysis used to detect the dynamic development of CE literature over time. By doing so, the paper explores the development of the CE body of knowledge, reveals its dynamic evolution over time, detects its main theoretical perspectives and research domains, and highlights its emerging topics. Our findings unfold the evidence of eight main trends of research about CE, unearth the path through which the CE concept emerged and has been growing, and concludes with promising avenues for future research.Sustainability 2020, 12, 1633 2 of 24 of CE, we explore the process of knowledge conception, dissemination and progress through a dynamic lens, with the aim to unearth its ongoing evolution. Accordingly, our main research question is: What are the existing themes and emerging research trends in Circular Economy?With this aim, we conduct a Systematic Literature Network Analysis (SLNA), which consists of a novel literature review method based on a dynamic approach that allows for uncovering how academics have addressed a specific topic over time since its early appearance. In other words, the SLNA results would complement the already existing systematic literature reviews about CE, in the sense that they supplement the reader with a synthesis of the dynamic development of the field, and a set of CE research development themes based on objective measurements.Scholars designed the SLNA as a quantitative-based method that builds on both systematic literature review and bibliographic network analysis [8]. The SLNA allows for embracing the knowledge of a field in its broader view and inherent value by identifying the main paths and key issues shaping its growth in a more rigorous way compared to conventional literature reviews [9]. Indeed, a conventional literature review usually relies on content analyses, which omit the dynamic evolution of the research. Moreover, the selection and categorization of literature relies on subjective, rather than objective tools. On the contrary, the SLNA relies on objective tools and algorithms (e...

“…Santibañez-Aguilar et al [29] developed a mathematical programming model used to determine the reuse of MSW to maximize the economic objective while considering the environmental and safety aspects simultaneously. Satchatippavarn et al [24] employed a superstructure optimization approach together with the biorefinery concept for the design of an integrated MSW management system. A case study in Bangkok presented the potentials and benefits related to achieving self-sufficiency.…”

The main objective of this study is to develop a decision-making tool for the design of the optimal municipal solid waste (MSW) facilities based on superstructure optimization. Currently, the disposal of MSW is a major problem due to the lack of awareness of the negative impacts resulting from dumping MSW into the environment. This poses a challenge for the authorities. MSW valorization such as anaerobic digestion (AD), pyrolysis, gasification etc has been increasingly focused on as an approach when handling MSW to enhance both economic and environmental sustainability. However, with an increasing array of processing technologies, the design of MSW facilities involving the integration of these technologies is becoming tedious and unmanageable. To deal with this problem, superstructure optimization is proposed. It is an effective tool for the design of several chemical processes because it is able to consider all potential process alternatives including the optimal solution using mathematical models based on mass and energy balances. Uncertainty is incorporated into the optimization framework to enhance the robustness of the solution. The proposed methodology was applied in the design process of the MSW facility in Ubon Rathathani province, Thailand, with the objective function of maximizing the profit. The optimization problem was developed as Mixed Integer Linear Programming (MILP) and it was solved using an optimization platform, GAMS, with CPLEX as the solver related to obtaining the optimal solution. The results show there to be as positive profit that is economically viable compared to the use of landfill technology.

“…71 The need to separate the biodegradable organics from other non-biodegradable solids, which is especially important for MSW, is also a problem that is limiting the diffusion of AD. For example, Satchatippavarn et al 72 reported that the municipality of Bangkok, Thailand, generates over 2.7 Mt of MSW per year of which 59% is biodegradable. However, the vast majority (over 85%) of this waste is dumped into landfills and open dumps and only 0.4% of it is treated by AD or composting.…”

The aim of this paper is to calculate the amount of energy or chemicals that can be produced using anaerobic digestion (AD). Five feedstocks were considered: the organic fraction of municipal solid waste (OFMSW); cattle, pig and poultry manure; energy crops; agricultural residues, and sewage sludge. Carbohydrates, proteins, and lipids were assumed to be the biodegradable components of the feedstocks. Chemical oxygen demand (COD) was assumed as a basis for the calculations of the production of methane and other chemicals. Methane production was calculated assuming that AD converts the biodegradable COD to methane with a yield of 80% COD/COD. The potential production of chemicals, i.e. acetic, propionic, butyric, and lactic acids, ethanol, and hydrogen, was calculated assuming conversion yields of carbohydrates, proteins, and lipids from the literature. Globally, with the assumptions made in this study, the AD of the feedstocks considered here can potentially satisfy 17–20% of the total energy consumption and 33–39% of the electrical energy requirements. Potentially, AD can generate organic acids at rates that are hundreds or thousands of times their current production rates. Ethanol and hydrogen can be produced by AD at rates that are up to 2–3 times their current production rate. This paper also discusses the main challenges that must be overcome to achieve the potential of AD. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd
