“…Despite the immense potential in resource recovery in developing countries, the execution of advanced technologies in waste management schemes at the provincial or nationwide level is still inadequate (Babu et al, 2021). The placement of facilities for recovering resources must be carried out in phases and requires grants and funding from the government (Yadav et al, 2021). Further research and development funding, particularly support for altering conventional supply chain procedures and correlated models into CSCs, are needed (Mulvaney et al, 2021).…”

The circular supply chain has recently received more attention as a relevant solution to effectively tackle environmental issues while simultaneously achieving resource recovery and circular business strategy benefits. This study builds a hierarchical circular supply chain structure from big data including qualitative and quantitative information. This study uses data-driven analysis to clarify circular supply chain trends and opportunities in practice. A valid hierarchical circular supply chain structure is composed of a big dataset. However, the attributes of the hierarchical circular supply chain structure must be explored to identify the opportunities and challenges of the circular supply chain. A combination of data-driven content and cluster analysis, including the fuzzy Delphi method, fuzzy decision-making trials, evaluation laboratories, and the entropy weight method, is utilized to address this gap. The study analyzes a set of five attributes from the literature, and 23 criteria are validated. The results show that resource recovery implementation, Industry 4.0 and digitalization, and reverse supply chain practice pertain to the causal group, while circular business strategy and life cycle sustainability assessment are included in the effect group. The conclusive criteria comprise material efficiency, waste-to-energy, machine learning, e-waste, plastic recycling, and artificial intelligence.

In this context, attention to the circular supply chain (CSC) concept is intensifying (Rweyendela & Kombe, 2021). The CSC concept offers sustainable advantages by separating value formation from resource usage, leading to lower resource consumption and higher economic value acquisition from waste flows (Bressanelli et al., 2021;Tseng, Tran, et al., 2021). Numerous studies have employed CSC principles to enhance resource efficiency by expanding the lifetime usage of a resource via a resource recovery procedure and improving the number of resources consumed along with the waste created (Krishnan et al., 2020;Munir et al., 2021). However, CSC initiation still involves an array of difficulties and complexities such as the diversification of the performance metrics of various opportunities and challenges in Abbreviations: CSC, circular supply chain; FDM, fuzzy Delphi method; FDEMATEL, fuzzy decision-making trial and evaluation laboratory; EWM, entropy weight method.

“…Therefore, they are looking toward shifting them to WRRFs, where many valuable resources could be recovered and released into the markets and industrial sector. The WRRF principle has already been investigated at different treatment technologies and scales 74. Kehrein et al 9 stated, however, that the application of WRRF is still facing several constraints due to the associated technical, and financial aspects.…”

Aerobic granular sludge (AGS) technology is gaining increasing interest globally. However, several aspects are still challenging its installation, as the integration into existing municipal wastewater treatment plants. The operation of AGS units in continuous flow mode could facilitate that integration; yet has only been experienced at lab and pilot scales. Further, handling of excess granular sludge constitutes a prominent challenge. Even that, adopting effective strategies for its management holds promising contributions to the circular economy by fostering the reuse and recovery of valuable resources. The recovery of phosphorus and alginate‐like polymers holds significant commercial potential worldwide, with broad applications in agriculture, food, pharmaceuticals, and biotechnology.

“…At the techno-economic level, the relevant assessment methods are cost–benefit analysis, technology phase assessment, techno-economic assessment, etc. , The development stage of technology can be measured by technology readiness levels (TRLs), and TRLs are widely used to manage the development of different technology stages. − For techno-economic assessment, some studies have proposed a techno-economic assessment framework for the chemical industry to measure technology in research, development, and deployment . At the level of environmental impact, life cycle analysis, eco-efficiency, environmental risk assessment, and external cost balance are widely used to measure the environmental impact of technologies. , LCA is considered as a method with the potential to evaluate the environmental impact of products and processes, and there are studies for municipal solid waste treatment technology assessment, wastewater recycling technology, and MgO production technology. − Eco-efficiency can measure the economic output of regions, sectors, enterprises, and technologies in relation to their environmental impacts . There are studies for the evaluation of technologies such as treatment for tile production, end-of-life tire treatment, acetic acid–water separation, and iron bar production. − There are studies that have developed a framework for risk assessment of treatment options for contaminated sites .…”

The sustainable utilization of the resources of the saline lake requires green technology applications, but now, the comprehensive evaluation methods to assess the sustainability of technology in the saline lake industry field are scarce. In this study, a model for assessing green technologies, reflecting elements of techno-economic evaluation, material flow analysis, life cycle assessment, eco-efficiency, circular economy, etc., is developed for assessing technology on technical, economic, and environmental aspects, comparing the technology of bischofite, a by-product of potash production, to fused MgO (target case) and magnesite to fused MgO (reference case) as the target to design three cases, namely, the target case, reference case, and blank case. The results show that in terms of comprehensive technology evaluation, the score of the target case is 70, slightly better than the reference case technology, which is reflected in better energy, water output rate, general industrial solid waste comprehensive utilization rate, etc. With regards to the environmental impact, the eco-efficiency value of the target case is 15.79 and the reference case is 4.03 owing to less SO 2 , CO 2 , and NO X emissions through the life cycle of the utilization of bischofite to fused MgO despite the fact that the net present value (NPV) of the target case (117 $/t pro.) is lower than that of the reference case (315 $/t pro.). Therefore, we conclude that the target case is superior to the reference case according to our multiple evaluation perspectives of economic, environmental, and technological considerations. The evaluation method can be more widely applied to the comparison of different technologies, especially in resource extraction, environmental protection, waste utilization, etc.
