Considering a growing number of metrics and indicators to assess circular economy, it is of paramount importance to shed light on how they differ from traditional approaches, such as life cycle assessment (LCA) or sustainability performance indicators. This study provides new empirical insights on the correlation between LCA, circularity, and sustainability indicator-based approaches. Specifically, the importance lies in analyzing how the results generated by these different approaches can be used to support the design of products that are not only circular, but also sustainable. A practice-based project involving 87 engineering students (divided into 20 groups) is conducted with the aim to compare and improve the circularity and sustainability performance of three product alternatives of lawn mowers (gasoline, electric, autonomous). To do so, the following resources are deployed: 18 midpoints environmental indicators calculated by LCA, eight product circularity indicators, and numerous leading sustainability indicators. Critical analyses on the usability, time efficiency, scientific soundness, and robustness of each approach are drawn, combining quantitative results generated by each group with the feedback of future engineers.

The current enthusiasm for circular economy (CE) offers a unique opportunity to advance the impact of research on sustainability transitions. Diverse interpretations of CE by scholars, however, produce partly opposing assessments of its potential benefits, which can hinder progress. Here, we synthesize policy-relevant lessons and research directions for a sustainable CE and identify three narratives – optimist, reformist and skeptical – that underpin the ambiguity in CE assessments. Based on 54 key CE scholars’ insights, we identify three research needs: the articulation and discussion of ontologically distinct CE narratives; bridging of technical, managerial, socio-economic, environmental and political CE perspectives; and critical assessment of opportunities and limits of CE science-policy interactions. Our findings offer practical guidance for scholars to engage reflexively with the rapid expansion of CE knowledge, identify and pursue high-impact research directions, and communicate more effectively with practitioners and policymakers.

Providing sufficient testing capacities and accurate results in a time-efficient way are essential to prevent the spread and lower the curve of a health crisis, such as the COVID-19 pandemic. In line with recent research investigating how simulation-based models and tools could contribute to mitigating the impact of COVID-19, a discrete event simulation model is developed to design optimal saliva-based COVID-19 testing stations performing sensitive, non-invasive, and rapid-result RT-qPCR tests processing. This model aims to determine the adequate number of machines and operators required, as well as their allocation at different workstations, according to the resources available and the rate of samples to be tested per day. The model has been built and experienced using actual data and processes implemented on-campus at the University of Illinois at Urbana-Champaign, where an average of around 10,000 samples needed to be processed on a daily basis, representing at the end of August 2020 more than 2% of all the COVID-19 tests performed per day in the USA. It helped identify specific bottlenecks and associated areas of improvement in the process to save human resources and time. Practically, the overall approach, including the proposed modular discrete event simulation model, can easily be reused or modified to fit other contexts where local COVID-19 testing stations have to be implemented or optimized. It could notably support on-site managers and decision-makers in dimensioning testing stations by allocating the appropriate type and quantity of resources.

Achieving environmental sustainability and transition from a linear economy to a circular economy (CE) highly relies on effective waste management (WM) and how waste is treated as a potential future resource. This research aims to provide an inclusive map of the scientific background of WM in the CE context over the last two decades from 2001 to 2020 to identify its salient research themes and trends, main characteristics, evolution, and potentially valuable directions for future studies. To achieve that, the following research questions were addressed by applying a mixed-method approach including bibliometric, text mining, and content analyses: (i) how has the field of WM research evolved within the CE domain? (ii) what are the salient research themes and trends of WM in the CE? and (iii) what are the possible directions for future research on WM within the CE context? As a result, the synthesized bibliometric networks were constructed and analyzed for a total of 962 journal articles extracted from the Web of Science database to visualize the main body of literature. Consequently, the seven major research themes of WM in the CE context were identified as follows: (1) bio-based WM; (2) CE transition; (3) electronic waste; (4) municipal solid waste; (5) environmental impacts and lifecycle assessment; (6) plastic waste; and (7) construction and demolition WM. The provided inclusive research landscape of WM systems, and its prominent highlight patterns can serve as a base for a real-time guideline to lead further research areas and as a tool to support WM policy-makers and practitioners to support the CE transition (which aims to minimize the waste generation). Finally, the future research directions to better position WM research activities within the CE context as a waste minimization approach are provided.

With the rapid development of new technology and the growing global competition in industry, it is essential for companies to protect their sensitive product designs and technologies. To ensure that their systems are not exploited by potential patent infringers, original equipment manufacturers often apply physical attributes and/or reduce commonality within a product family to prevent easy reusing and recovering. Yet, these design strategies are key barriers to the sustainable recovery and recycling of products. To address these trade-offs, this paper proposes a stepwise methodology to identify the sustainable optimal product family architecture design while protecting intellectual property on sensitive parts or modules. The developed approach notably allows the selection of suitable and sustainable candidates to share among products, taking into account the cost-benefit of commonality within the product family. To demonstrate and test the proposed methodology, a case study is performed with a printer-product family. Environmental savings resulting from the new modular-based architecture obtained for this product family are quantified and discussed.

Due to recent technological advancements, automation and autonomous solutions are gaining increasing popularity. Yet, a lack of in-depth investigations is noticed on the potential environmental benefits and economic repercussions of implementing autonomous systems. The present study aims to fill part of this gap by quantifying the environmental and economic sustainability of a robotic lawn mower, in comparison with human-operated counterparts. Combining life cycle assessment and life cycle costing methodologies, and by defining adequate functional units, building simulation models, and collecting life cycle inventory data, a systematic comparative study between autonomous and conventional lawn mowers is performed on their environmental and economic impacts. Through this multi-indicator analysis, environmental and economic trade-offs between the autonomous and conventional mowing solutions are quantitatively discussed for key relevant usage scenarios, from mowing an average residential yard to maintaining larger fields like a football stadium or a schoolyard. Concretely, sensitivity analyses on key parameters influencing the performance of the autonomous mower have been conducted to evaluate the environmental and economic benefits of an augmented robotic mower. While optimising the path planning of the current robotic mower would lead to the most substantial savings, improvements on the battery performance, cutting width, and speed of the autonomous solution appear as other promising areas for future work.

Efficient electronic waste (e-waste) management is one of the vital strategies to save materials, including critical minerals and precious metals with limited global reserves. The e-waste collection issue has gained increasing attention in recent years, especially in developing countries, due to low collection rates. This study aims to search for progressive solutions in the e-waste collection sphere with close-to-zero transport and infrastructure costs and the minimization of consumers’ efforts towards an enhanced e-waste management efficiency and collection rate. Along these lines, the present paper develops a smart reverse system of e-waste from end-of-life electronics holders to local recycling infrastructures based on intelligent information technology (IT) tools involving local delivery services to collect e-waste and connecting with interactive online maps of users’ requests. This system considers the vehicles of local delivery services as potential mobile collection points that collect and deliver e-waste to a local recycling enterprise with a minimum deviation from the planned routes. Besides e-waste transport and infrastructure costs minimization, the proposed smart e-waste reverse system supports the reduction of CO2 through the optimal deployment of e-waste collection vehicles. The present study also advances a solid rationale for involving local e-waste operators as key stakeholders of the smart e-waste reverse system. Deploying the business model canvas (BMC) toolkit, a business model of the developed system has been built for the case of Sumy city, Ukraine, and discussed in light of recent studies.

Implementing circular economy (CE) practices can lead to both environmental savings and competitive advantages for companies. While transitioning from a linear production system to a closed-loop system is not straightforward, adequate methodology and tools can support industrialists in this sustainable shift. This paper proposes a multi-tool approach to systematically identify, classify, and assess the contribution of influence parameters and action levers to close the loop on products and key materials. Industrial ecology and model-based engineering tools are combined to ensure a systemic analysis and evaluation. The developed multi-tool approach combines, in a stepwise methodology, material flow analysis, fuzzy cognitive mapping, structural analysis, and system dynamics, to model and qualify the impact of potential and promising CE strategies. To illustrate each step of this multi-tool methodology, a case study is carried out on a real-world industrial product: a catalytic converter, which contains a non-negligible amount of platinum, considered as a critical raw material by the European Commission. New insights to close the loop on platinum from catalytic converters are thus provided and discussed. Notably, the connections between key action levers to close the loop on platinum are identified and highlighted, including regulations to limit the number of exports, mandatory recycling and reuse rate, end-users behaviors, based on regulatory constraints and financial motivations, and platinum price fluctuation. These findings could help to generate and fine-tune an ad hoc system dynamics model to evaluate the impact of key action levers through more specific scenarios. For instance, the broader implication of this multi-tool methodology could support an original equipment manufacturer in the evaluation of potential CE strategies, through the simulation of selected action levers on the circularity and sustainability performance of their value chain. Ultimately, it could provide quantitative insights to relevant prospective questions, such as, what if a take-back scheme is proposed to augment the collection rate by a given percentage, or what if the design is modified for easy disassembly.

Sustainable design methods and tools abound, but their implementation in practice remains marginal. This article brings together results from previous literature reviews and analyses of sustainable design methods and tools, as well as input from design researchers and professional practitioners to identify the needs and gaps in the area. It results in a shared vision of how sustainable design methods and tools can be more tightly integrated into mainstream product design and development, as well as the current state of practice and research in relation to four central questions: What are the needs and values of industry regarding sustainable design? What improvements in sustainable design methods and tools would most drive industry forward? How should researchers move forward with developing more useful sustainable design methods and tools? How can sustainable design be more effectively integrated into industry? A roadmap for the international sustainable design research community is proposed with descriptions of short-, medium-, and long-term tasks for addressing each question. The purpose is to support collective progress and discussions on method and tool development and adoption, and to enable more tangible success in mainstreaming sustainable design practices in industry.

The recent development in technology has made bio-based plastics an increasingly attractive alternative to petroleum-based plastics to tackle plastic pollution. However, currently, bio-based plastics have not been widely adopted in the design and manufacturing of new products. To advocate the use of bio-based plastics, this paper proposes two visualization-based tools to educate designers and engineers about the availabilities and the properties of different bio-based plastics. After analyzing the literature on visual tools for sustainable design and material selection, two new prototype tools for screening bio-plastic alternatives are designed with the advice and support of the engineers of a major U.S. manufacturer of agricultural equipment. Surveys and focus groups with the manufacturer’s engineers are conducted to improve the tools, and a first case study is completed to examine their usefulness.

The developed approach notably allows the selection of suitable and sustainable candidates to share among products, taking into account the cost-benefit of commonality within the product family. As such, it can be used as a decision support tool to help product designers identify appropriate product family architecture design and find candidates that can be shared within a product family by considering both sustainability and security parameters.

While autonomous machines are considered as a new opportunity to augment safety, reliability, productivity, and efficiency, the actual environmental and economic sustainability performances of many autonomous systems remain yet to be quantified. The present research aims to fill part of this gap by evaluating the life cycle impact and cost of autonomous solutions in the agricultural industry. Comparative life cycle assessment (LCA) and life cycle costing (LCC) are carried out on a real-world case study putting in parallel a robotic electric lawn mower (autonomous solution) and conventional – gasoline- and electricity-powered – pushing mowers (human-operated counterparts). Results are interpreted in terms of global warming potential and total cost of ownership. While the autonomous system already appears to be a promising sustainable alternative, discussions and quantitative insights are also provided on the conditions that would lead to further environmental savings and economic profit for this autonomous solution.

This paper investigates and questions the relevance of product-centric circularity indicators in a product design context. To do so, reviews of eco-design tools and critical analyses of circularity indicators at the micro level of circular economy implementation are combined with a new workshop experimenting four of these indicators with the aim to improve the circularity performance of an industrial product. On this basis, the four tool-based circularity indicators tested are mapped on the engineering design and development process, and are positioned among the pool of main eco-design tools.

To date, a limited number of in-depth case studies addressing the end-of-life management of heavy vehicles has been reported in the scientific literature. An action research approach is conducted in collaboration with an emerging international remanufacturing center of heavy handling machines to bring a contribution to this gap in a circular economy perspective. This industrial pilot study considers the entire end-of-life management of a whole heavy vehicle, from the dismantling to the recovery of used parts, through remanufacturing. It illustrates as such the multiple dimensions to consider when closing-the-loop on heavy vehicles, namely: technical and organizational knowledge (e.g., infrastructures, tooling, dismantling process and remanufacturing feasibility), as well as economic considerations (e.g., solutions to optimize the value recovered according to market needs, through the identification of potential recovery channels). To do so, a multi-scale modeling is proposed, taking into account: (i) the condition of the used vehicle and residual values of key components, (ii) the dismantling process and capabilities, (iii) the possible end-of-life options and associated market. A first dismantling operation on a worn-out 8-ton forklift truck is performed and closely analyzed to identify hotspots and areas for improvement. Based on that and taking inspiration from the best practices of the automotive recycling sector, a new dismantling process is designed including improvement in terms of organisation, resources used, disassembly time, and comfort for the operator. This newly proposed process is then tested and validated through a second dismantling experimentation on a similar forklift truck. Moreover, a practical spreadsheet, to be used by the industrialist, is proposed and applied as a decision-making support tool to compare and select the most appropriate end-of-life pathways for recovered components according to the economic aspects of each circular option, among reuse, remanufacturing and material recovery. Eventually, lessons learnt from this industrial case study open up on broader implications and challenges (e.g., the applicability, generalization and scaling-up of commendable practices from one industrial sector to another) to achieve a more advanced circular economy in the heavy vehicle industry.

The purpose of this paper is to develop and discuss a framework aiming at monitoring and optimizing the circularity performance of products for ensuring and facilitating green profit design trade-offs whilst meeting or anticipating end-of-life regulations during the design and development process of industrial products. The proposed framework is used to extend the Green Profit Model — an optimization model to maximize the total profit from the sales of new and remanufactured products, while achieving environmental impact savings — by adding a third dimension to this model, which is the circularity performance. As such, in addition to remanufacturing, it covers a wider spectrum of circular economy practices, leading to additional economic opportunities and environmental trade-offs between maintenance, reuse, remanufacturing and recycling at a product, parts and material levels. A first formulation of this extended optimization model is given and discussed through an illustrative example. By connecting the circularity performance of products with possible economic profit and environmental impact savings, it thus contributes in advancing the understanding and linkages in the area of circular design, life cycle analysis, industrial decision-support tool, and environmental regulations. Concretely, practical implications for both design engineering and green policy making are highlighted.

Monitoring properly the circularity performance of technical products is a point of increasing importance. Yet, evaluating the circularity potential of products during (re)design and development phases is a challenging task. In this study, several C-indicators are experienced by doctoral students and industrialists through two workshops on a real-world industrial product. The values obtained for each indicator are collected and analyzed: as all participant are working on the same technical product with the same dataset, the circularity scores calculated are compared to discuss the reliability and the uncertainty related to these indicators. These new empirical insights are put in parallel with the existing critical analyses of C-indicators from literature. As a result, future research directions on circularity indicators are advanced and discussed, including: the integration of uncertainty considerations into the assessment methodology of circularity indicators; the uptake by industry of such indicators during product design and development; the link between circularity and sustainability scores.
