Global water scarcity is aggravating with increasing urbanization and inappropriate urban water management. Implementing Circular Economy (CE) strategies in the water sector followed by their assessment can prove to be beneficial. Recently, the Water Circularity Indicator (WCI) has been developed to measure, monitor, improve and promote urban water circularity using the 5Rs (Reduce, Reuse, Recycle, Reclaim, Restore). Apprehending the role and scope of each strategy is crucial while planning future water infrastructure, as each strategy has inherent advantages and limitations in application. This study aims to facilitate decision-makers with an approach to prioritize 5Rs CE strategies, which will be helpful in the efficient allocation of funds and resources related to water infrastructure. A methodology is proposed to prioritize and weigh 5Rs based on the effort required to fulfill the application of each strategy. Using weights assigned to each R, WCI is improved to WCI-2.0 and is evaluated for the region under the jurisdiction of Pimpri-Chinchwad Municipal Corporation. The results from WCI-2.0 suggest which strategy to focus on out of the 5Rs to accelerate water circularity and effective infrastructure planning. Benchmarking of WCI-2.0 and its use to propose policies supporting urban water balance has the potential to change the prospects of the water sector. HIGHLIGHTS A methodology to prioritize water circularity strategies is proposed.; Prioritizing Circular Economy (CE) strategies is essential.; Prioritization helps in the efficient allocation of funds and resources.; Water Circularity Indicator (WCI) is reformulated and improved.; WCI can be used for benchmarking and future infrastructure planning.;

Circular Economy (CE) is considered a possible solution to mitigate the environmental externalities of the tourism industry, with a view to more sustainable tourism by reducing environmental, social, and economic burdens in an integrated holistic approach. Moreover, the role of CE in tourism is highlighted by the possibility of achieving all sustainable development goals (SDGs) directly and indirectly using the links that connect SDG 12 with the others.From this point of view, this literature review was aimed at discussing the key strategies of CE applied to the tourism industry, focussing on the widespread problems of single-use plastic, excess food, and water consumption. The environmental and socio-economic benefits deriving from the application of the CE principles to waste management will be shown, by contributing to meeting all the SDGs. Many strategies have been proposed to make tourism circular and sustainable, and research revealed that those are mainly based on the concepts of reduce, reuse, recycle, and recover.This article confirmed the importance of – and the need for - research on CE in the tourism sector; further, by contributing to expanding research in this content area, it can stimulate the development and application of solutions that make the industry more efficient and resilient. This study was also conceived to raise the awareness of tourism stakeholders on the importance of CE to mitigate the negative externalities of the sector.

This study looks at the Northern border sanitation program gran vision study and the Northern border strategic sanitation program both programs were formulated after introducing the environmental chapter of the usmca in 2020. The study examines three relevant cases of border cities: Tijuana, Baja California; Nogales, Sonora; and, Nuevo Laredo, Tamaulipas. The research is based on a documentary review and interviews with key informants. The study found that the proposed solutions were mainly based on conventional infrastructure projects, with limited incorporation of reuse, recycling and recovery strategies for materials, energy and water. The study emphasizes the importance of holistic planning that incorporates circular economy principles and green infrastructure to improve the sustainability of sanitation projects in the region.

This study aims to propose and empirically validate the application of a methodology for determining the business model (BM) dynamics associated with the implementation of selected circular economy (CE) strategies and the competitiveness of enterprises. The methodology is based on the assumptions of the attention-based view theory and legitimacy theory, which apply to the analysis of corporate communication. Key variables were identified and quantified using the verbal semantic indicators of BM and CE. The strength of the relationships between the variables was measured through correlation analysis, considering the selected moderating factors. The qualitative part of this study is based on empirical case studies of leading industrial enterprises operating in the European decorative and information systems manufacturing sectors. In the quantitative part, corporate reports were analysed and evaluated. Using the proposed IBMDRi index, the dynamics exhibited by the BMs of the studied industrial enterprises in the implementation of different CE strategies were monitored. These results indicate that BM dynamics can be higher when implementing lower-level CE strategies than higher-level CE strategies. The main scientific contribution of this study is the development and application of a quantitative methodology for IBMDRi determination. The methodology is applicable both in ongoing academic research in the fields of BM and CE and in the practitioner's sphere for the purpose of designing BM, determining and comparing applied BMs, and implementing CE strategies across companies and industries.

Global industrialization and excessive dependence on nonrenewable energy sources have led to an increase in solid waste and climate change, calling for strategies to implement a circular economy in all sectors to reduce carbon emissions by 45% by 2030, and to achieve carbon neutrality by 2050. Here we review circular economy strategies with focus on waste management, climate change, energy, air and water quality, land use, industry, food production, life cycle assessment, and cost-effective routes. We observed that increasing the use of bio-based materials is a challenge in terms of land use and land cover. Carbon removal technologies are actually prohibitively expensive, ranging from 100 to 1200 dollars per ton of carbon dioxide. Politically, only few companies worldwide have set climate change goals. While circular economy strategies can be implemented in various sectors such as industry, waste, energy, buildings, and transportation, life cycle assessment is required to optimize new systems. Overall, we provide a theoretical foundation for a sustainable industrial, agricultural, and commercial future by constructing cost-effective routes to a circular economy. [ABSTRACT FROM AUTHOR]

• Constructed a four-layer framework based on material closed-loop circulation. • Evaluated the material and CO 2 reduction of 7 circular economy strategies (CES). • By 2060, 49.64 Mt of materials will be required annually, producing 8.26 Mt of CO 2. • CES reduced material demands by 20.40–762.09 Mt and CO 2 emissions by 2.62–157.46 Mt. • More efforts are needed to achieve China's "3060" goals. The circular economy strategy can effectively reconcile the contradiction between human activities and the ecological environment through utilizing resources efficiently and circularly, thereby promoting global low-carbon sustainable development. However, it lacks application in urban buildings. This study constructs the four-layer framework based on the turnover dynamic stock model and carbon emissions method. Combined with 7 circular economy strategies and scenario analysis, this framework captures the production, demand, use, recycling and reuse of 13 major materials in 7 prototypes of 3 types for Beijing's buildings, and explores the potential of dematerialization and low-carbon development from 2022 to 2060. Results indicate that the floor area will continue to grow to 1749.00 million m2 by 2060, material requirements will increase by 49.64 Mt annually, and CO 2 emissions will increase by 8.26 Mt annually under current policies. Circular economy strategies can reduce cumulative material requirements by 20.40–762.09 Mt and CO 2 emissions by 2.62–157.46 Mt until 2060, which have enormous abatement potential for materials and CO 2 emissions. Executing multi-strategy simultaneously demonstrates superior overall effectiveness compared to individual strategies, which resulted in a cumulative reduction of 40.40 % of material requirements and 50.14 % of CO 2 emissions. Decarbonizing buildings, promoting sustainable development, and contributing to achieving "3060" dual carbon goals require a collaborative implementation of multiple strategies.

Incumbent B2B manufacturing companies join forces and form collaborative networks, called consortia, aiming to increase the circularity of their products. Our research interest lies in the understanding of how the business models (BM) of the companies and the industry are affected by such collaborations in the collaborative networks of the circular economy (CE). Given the exploratory nature of our empirical research, we applied a mixed research strategy of an inductively deductive nature. We carried out case studies in a manufacturing industry field and combined them with quantitative content analyses of the companies' financial and non-financial reports. Drawing on the assumptions of the Attention-Based View Theory and Legitimacy Theory, we defined and found verbally communicated identifiers of BM elements, CE strategies, and collaborative networks, quantified their occurrences, and transformed them into variables. Using correlation analyses, we determined the tightness and the changes in relationships between the BMs' elements and CE strategies. We examined the dynamic changes in the structure of BMs and their elements occurring within the implementation of selected CE strategies. Our findings suggest that collaborative networks for CE support an adaptation of the industry's BMs. The higher-level CE strategies impact the BM more than the lower-level ones. The contribution of our research is in the suggested method of quantification and concretization of an abstract concept of BMs' elements and their interrelations. This enables an assessment and a direct comparison of BMs, as well as of implemented CE strategies across companies and across industries. Our results also shed more light on the way the companies and industries adapt their BMs towards reaching circularity, as well as on how collaborative networks support such a transition.

In transitioning to a circular economy with sustainable waste management, the role of waste management sector shifts from being a regulator to being a facilitator. Instead of just regulating waste flows, the sector tries to encourage businesses to address all aspects of circular economy sustainability in a more efficient manner. The sustainability assessment in the sector lacks a hybrid method to aggregate the sustainability dimensions of circular economy strategies into a single summary indicator. This process is a multiple-criteria decision-making problem that requires the integration of circular economy strategies to form the sustainability indices. In order to make the right choices here, this study proposes a fuzzy three-phase group multiple-criteria decision-making approach. This approach integrates fuzzy analytic network process (fuzzy ANP), fuzzy decision-making trail and evaluation laboratory (fuzzy DEMATEL) and fuzzy multi-objective optimization on the basis of ration analysis (fuzzy MULTIMOORA). In addition, a proposed aggregate circular economy-based sustainability index is applied to calculate the closeness of the outcomes of the hybrid method to the ideal strategies. The performance of the method is evaluated in the real-world cases concerning the selection of the most suitable circular economy strategies for a sustainable waste electrical and electronic equipment management practice.

Life cycle engineering of new products and technologies must consider not just the single product and product life cycle, but also the foreseeable growth in market volume that results from increases in population and affluence, in order to allow the associated total environmental impact to be taken into account during the product development. The emphasis should not only be on eco-efficiency but also in eco-effectiveness. In the context, eco-effectiveness provides the target (e.g., 2050 targets), while ecoefficiency provides a progressive pathway to get there. The main aim of this special issue is to create a platform for researchers around the world in the area of Life Cycle Engineering and Sustainable Manufacturing for achieving net-zero targets and environmental sustainability.

Different studies in the scientific literature have shown how the transition towards a circular economy (CE) can benefit from product design, although maintaining a rather broad and qualitative perspective of analysis. This study investigates and compares which product design strategies (from routinely design, structural optimization, industrial design and systematic innovation) are most used by students and professional designers to implement different CE strategies (i.e., waste reduction, reuse, remanufacturing, recycling and biodegradability). Students' data were collected from year projects and MSc degree theses based on real industrial case studies and carried out in two Italian engineering universities, while those of professional designers, were collected from selected scientific articles. Among the main outcomes emerged that the design strategies deriving from systematic innovation were preferred by students quite clearly. The design strategies referred to industrial design, e.g., user-centered design and timeless design were preferred by professional designers. The design strategies related to routine design, i.e., materials substitution, reducing resources and energy consumption, and structural optimization, were indistinctly used by both students and professional designers. The obtained results and their discussion can be useful during eco-design teaching to show the main gaps that students should fill in comparison with professional designers. [ABSTRACT FROM AUTHOR]

The objective of this study was to develop new indicators that reflect economic growth by taking into account the impact on the environment and natural resources as well. The indicator calculated by subtracting environmental cost from the "Gross Domestic Product (GDP)" and is used in the assessment of the GDP by taking into consideration the cost of natural resources and the environment, called "green GDP". This study uses Life Cycle Assessment, which is a technique used to assess the environmental impact of sugar industry from raw materials, distribution, production, and waste management. The system boundary for the life cycle inventory are cultivation, planting, transportation and sugar production. The results of the green GDP and GDP is difference about 6–12% due to the depletion cost resulting from the use of natural resources between 9.0–9.52 $/ton of sugar production and the degradation cost caused by the airborne emission and waterborne emission between 37–57 $/ton of sugar production. The quantity of Total Suspended Particulate (TSP) generated from the sugar production process is the main causing the environmental cost about 55%. In order to solve environmental causes, the policy making as Circular Economy Strategies can be used to meet the sustainable development in the future. [ABSTRACT FROM AUTHOR]

The goal of this research is to theoretically integrate the CE paradigm within the environmental sustainability framework. Based on the shortcomings detected in the circular economy literature, we followed a three steps procedure. Firstly, we conducted a narrative literature review that underlies the need of understanding the circular economy as a resilient, sustainable and circular economy, and we identified twelve principles to operationalize the circular economy under the environmental sustainability paradigm. Secondly, we created a database containing information on twenty-six strategies of circular economy. Thirdly, we analyzed the data to assess how the principles explored in phase 1 are being considered by the current circular economy strategies. Results revealed a high variability of approaches performed by the governments to reach the circular economy. Moreover, strategies grouped into the resilience domain are barely incorporated into circular economy strategies, and hence some circular economy strategies reveal shortcomings in their capacity to generate real changes. Further research is needed to perform a more holistic analysis based on complex adaptative system thinking, which would allow connecting more essential elements to enhance a socially fair development that preserves the environment. • Circular economy was integrated into the just and safe operating space narrative. • Circularity, sustainability and resilience domains were detected to be essential. • The objectives were channeled into actions through twelve operational principles. • Most circular economy strategies present shortcomings to generate real changes. • Most circular economy strategies are disconnected from environmental goals.

Circular economy (CE) and sustainability are interrelated, without being exchangeable. While sustainability tries to reconcile the management of productive resources with their increasing consumption, CE aims to make the productive process more efficient, reducing, reusing and recycling the results of the productive process as much as possible. The aim of this paper is to ascertain the systemic structure of interactions between sustainability and CE through the analysis of the existing literature from 2004 to 2021. For this purpose, a computational literature review and a content analysis of the main contributions of CE and sustainability, within the framework of the Sustainable Development Goals (SDGs), were conducted. The results show that there is a positive impact of the synergy between CE strategies and certain SDGs. Specifically, the circular strategies that generate the greatest synergies have to do with preserving materials through recycling, downcycling, and the measurement of indicators or reference scenarios. This is what has led to the inclusion of these concepts in the formulation of policies and strategies, as their multidisciplinary nature allows them to have an impact on areas such as agriculture or innovation, which currently lack specific measures. Therefore, the knowledge derived from this study will contribute favorably to future decisions and actions to be considered, as there is still the potential to legislate in favor of an even more sustainable framework.
