A mathematical framework that provides practical guidelines for user adoption is proposed for fuel cell performance evaluation. By leveraging the mathematical framework, two measures that describe the average and worst-case performance are presented. To facilitate the computation of the performance measures in a practical setting, we model the distribution of the voltages at different current points as a Gaussian process. Then the minimum number of samples needed to estimate the performance measures is obtained using information-theoretic notions. Furthermore, we introduce a sensing algorithm that finds the current points that are maximally informative about the voltage. Observing the voltages at the points identified by the proposed algorithm enables the user to estimate the voltages at the unobserved points. The proposed performance measures and the corresponding results are validated on a fuel cell dataset provided by an industrial user whose conclusion coincides with the judgement from the fuel cell manufacturer.

Circular business models are often enabled by means of product/service-systems (PSS). The common perception is that such business models have enhanced environmental performance when compared to conventional business models rooted in the linear economy. This article investigates the environmental potential of developing a use-oriented PSS business model for Merino wool t-shirts intended for use by the British Ministry of Defence as an alternative to the present supply system based on synthetic t-shirts purchased from sportswear clothing companies. To conduct the assessment, we apply the life cycle assessment (LCA) methodology to quantify and compare the climate change impacts and impact potentials of the proposed PSS business model and of a reference business model. Results showed that there could be significant contribution of quantifying environmental potential for PSS business models when justifying the transition to a circular economy. However, when adopting LCA methodology for this purpose, the design of the PSS needs to be well thought to overcome some of the identified challenges. The article concludes by making the case that LCA studies can support the definition, design and value creation of the product/service-systems in early development stages.

The emergence of new technologies such as the Internet of Things, big data, and advanced robotics, together with risks such as climate change, rising labour costs, and a fluctuating economy, are challenging the current UK manufacturing model. In this paper, business models for re-distributed manufacture (RdM) are developed using anIDEF (Icam DEFinition for Function Modelling) description to serve as a guide for the implementation of the RdM concept in the consumer goods industry. This paper explores the viability of a re-distributed business model for manufacturers employing new manufacturing technologies such as additive manufacturing or three-dimensional (3D) printing, as part of a sustainable and circular production and consumption system. An As-Is value chain model is presented alongside the proposed new business model for a sustainable re-distributed manufacturing system. Both are illustrated via a case study drawn from the shoe manufacturing industry. The case study shows that there is a need for robust facilities in close proximity to the customer. These facilities are store fronts which can also manufacture, remanufacture, and provide services. The reduction in transportation and increase in customer involvement throughout the process are the main benefits that would accrue if a re-distributed model is implemented in the given industry.

Many studies have explored the integration of Circular Economy thinking within a business model context, however, researchers have yet to identify and demonstrate the full range of benefits and value that is available if organisations were to transition to a circular model. Through a literature review and analysis of ten case studies of sustainable businesses, this paper uncovers the categories and types of value that are available within a Circular Economy system and consolidates them into taxonomy and framework of value. Through the use of affinity mapping, the taxonomy of value identified and included: categories of value, tangible/explicit value, intangible/implicit value; methods and strategies for generating value and stakeholders for whom value is created. This paper outlines these values in more detail providing a clear starting point for organisations to realise the benefits that a Circular Economy system affords.

This paper presents an investigation on how simulation informed by the latest advances in digital technologies such as the 4th Industrial Revolution (I4.0) and the Internet of Things (IoT) can provide digital intelligence to accelerate the implementation of more circular approaches in UK manufacturing. Through this research, a remanufacturing process was mapped and simulated using discrete event simulation (DES) to depict the decision-making process at the shop-floor level of a remanufacturing facility. To understand the challenge of using data in remanufacturing, a series of interviews were conducted finding that there was a significant variability in the condition of the returned product. To address this gap, the concept of certainty of product quality (CPQ) was developed and tested through a system dynamics (SD) and DES model to better understand the effects of CPQ on products awaiting remanufacture, including inspection, cleaning and disassembly times. The wider application of CPQ could be used to forecast remanufacturing and production processes, resulting in reduced costs by using an automatised process for inspection, thus allowing more detailed distinction between “go” or “no go” for remanufacture. Within the context of a circular economy, CPQ could be replicated to assess interventions in the product lifecycle, and therefore the identification of the optimal CE strategy and the time of intervention for the current life of a product—that is, when to upgrade, refurbish, remanufacture or recycle. The novelty of this research lies in investigating the application of simulation through the lens of a restorative circular economic model focusing on product life extension and its suitability at a particular point in a product’s life cycle.

The linear production of consumer goods is characterised by mass manufacture, multinational enterprises and globally dispersed supply chains. Redistributed manufacture (RDM) is an emerging topic, which seeks to enable a transition of the current linear model of production and consumption, by taking advantage of new technologies. This paper aims to explore the challenges, opportunities and further research questions to set a vision of Redistributed manufacturing for the UK’s consumer goods industry. To set this vision, a literature survey was conducted followed by a qualitative enquiry where PESTLE1 aspects of RDM were analysed. This analysis was interpreted through a roadmap. As a result of this roadmap, four RDM characteristics (i.e. customisation, use of digital technologies, local production and the development of new business models) were identified. These characteristics helped to set the future vision of RDM in the UK’s consumer goods sector.

An emergent vision for industrial sustainability is moving beyond the circular economy into the possibility of "immortal" products. This requires development of methods to enable the reliable and scalable production of novel products and systems that possess the inherent ability to sense and repair damage enabling in service healing and immortality. In the literature, this is mostly described by the self-healing property of the materials (polymers, metals, composites, ceramics and bio and non-bio hybrid systems). Self-healing systems are generally classified according to material type and self-repairing autonomy. This paper presents a brief review of existing immortal products and current methods of assessment. The paper presents an amalgamation of published research in the form of new process windows for the selection of self-heling materials and systems. Another contribution is made by the development of new metrics for assessing self-healing capability, with a vision to produce healing metrics that incorporate technical performance, as well as social, environmental and economic impact.

Emotional appraisal research has demonstrated that recalling a past behavior and its associated emotions can influence future behavior. However, how such recalled emotions shape sustainable consumer choice has not been examined. This study examines the role of recalled pride and guilt in shaping sustainable purchase intentions and the mediating role of anticipated pride and guilt. A conceptual model is proposed for motivating sustainable purchase intentions through the emotions associated with the behavioral recall. The model is applied in two experiments with online consumers examining purchase intentions of low carbon cars. Recalling feelings of pride associated with a past sustainability‐related behavior increases sustainable purchase intention, as compared with a neutral recall. This effect occurs through the mediation of both anticipated pride at the prospect of a sustainable behavior choice and anticipated guilt if the future choice is not sustainable. Similar hypotheses relating to recalled guilt at past unsustainable behavior were not supported. The study contributes to research on sustainable consumption, revealing an emotional route by which past behavior can influence future behavior. It also adds to emotional appraisal research by showing the role of specific self‐conscious emotions in forming this route, as prior research has focused more broadly on emotional valence.

The aim of the study is to envision, through an inductive scenario planning methodology, future scenarios of the fast-moving consumer goods (FMCG) industry in the context of a circular economy (CE). The study uses an exploratory scenario planning, an inductive approach to engage FMCG industry organisations, CE experts, end-users, and academic stakeholders in exploring the future of FMCG within a CE context. Five future scenarios that can inform a vision for the future of the FMCG industry were developed: (1) Rinse and Reuse, (2) The Cycling of Pure Materials, (3) The Rise of the Circular Retailer, (4) A World Without Supermarkets and (5) Connected Living. The analysis and discussion of the scenarios consider how value is created within circular economy and the integral role that the consumer and the IT play within it. The study provides insights on how the FMCG sector might participate in the CE and in doing so provides a basis for further research in this area. Future areas for research are outlined.

Manufacturing industries are experiencing a data-driven paradigm shift that is changing how technical operations are run and changing present business models. Leveraging on manufacturing data from industries and digital intelligence platforms have become important in creating new forms of value. While extending the life of a product through the circular economy 3 R’s of reuse, re-manufacturing and recycling remains a technical and resource challenge for practitioners, optimizing the increasing forms and volumes of data presents a complementary and necessary challenge to the circular economy. This research aims to explore how the manufacturing data can inform remanufacturing parameters for implementing remanufacturing on the Rechargeable Energy Storage System.

Remanufacturing is a viable option to extend the useful life of an end-of-use product or its parts, ensuring sustainable competitive advantages under the current global economic climate. Challenges typical to remanufacturing still persist, despite its many benefits. According to the European Remanufacturing Network, a key challenge is the lack of accurate, timely and consistent product knowledge as highlighted in a 2015 survey of 188 European remanufacturers. With more data being produced by electric and hybrid vehicles, this adds to the information complexity challenge already experienced in remanufacturing. Therefore, it is difficult to implement real-time and accurate remanufacturing for the shop floor; there are no papers that focus on this within an electric and hybrid vehicle environment. To address this problem, this paper attempts to: (1) identify the required parameters/variables needed for fuel cell remanufacturing by means of interviews; (2) rank the variables by Pareto analysis; (3) develop a casual loop diagram for the identified parameters/variables to visualise their impact on remanufacturing; and (4) model a simple stock and flow diagram to simulate and understand data and information-driven schemes in remanufacturing.

Since it first appeared in literature in the early nineties, the Circular Economy (CE) has grown in significance amongst academic, policymaking, and industry groups. The latest developments in the CE field have included the interrogation of CE as a paradigm, and its relationship with sustainability and other concepts, including iterative definitions. Research has also identified a significant opportunity to apply circular approaches to our rapidly changing industrial system, including manufacturing processes and Industry 4.0 (I4.0) which, with data, is enabling the latest advances in digital technologies (DT). Research which fuses these two areas has not been extensively explored. This is the first paper to provide a synergistic and integrative CE-DT framework which offers directions for policymakers and guidance for future research through a review of the integrated fields of CE and I4.0. To achieve this, a Systematic Literature Review (SLR; n = 174) of the empirical literature related to digital technologies, I4.0, and circular approaches is conducted. The SLR is based on peer-reviewed articles published between 2000 and early 2018. This paper also summarizes the current trends in CE research related to manufacturing. The findings confirm that while CE research has been on the increase, research on digital technologies to enable a CE is still relatively untouched. While the “interdisciplinarity” of CE research is well-known, the findings reveal that a substantial percentage is engineering-focused. The paper concludes by proposing a synergistic and integrative CE-DT framework for future research developed from the gaps in the current research landscape.

The linear production of consumer goods is characterised by mass manufacture by multinational enterprises and globally dispersed supply chains. The current centralised model has created a distance between the manufacturer and end user, limiting the opportunity for intelligent circular approaches for production and consumption. Through a mixed method approach, opportunities of circularity are explored for the consumer goods sector. The study presents four lenses to analyse three enterprises through a multi-case study approach to explore the potential of digital intelligence and redistributed manufacturing (RDM) as enablers of circular business models. In addition, the study examines whether Discrete Event Simulation can be used to evaluate the circular scenarios identified through quantifying flows of material that determine traditional economic value (cost/tonne). The mixed method approach demonstrates that, a qualitative systemic analysis can reveal opportunities for circularity, gained through implementing ‘digital intelligence’ and distributed models of production and consumption. Furthermore, simulations can provide a quantified evaluation on the effects of introducing circular activities across a supply chain.

In a world dominated by linear economic systems, the road to improving resource use is multi-faceted. Whilst public and private organisations are making progress in introducing sustainable practices, we ask ourselves the extent to which education providers are contributing to the circular economy. As engines for skills and knowledge, universities play a primary role in propelling circular economy approaches into reality and, as such, hold the potential for raising the bar on sustainable performance. A rapid evidence assessment (REA) was therefore undertaken to examine the interactions between university estate management and the circular economy. This assessment identified six pertinent themes: campus sustainability, the hidden curriculum, environmental governance, local impact, university material flows, and the role of universities as catalysts for business and examined 70 publications. A second part of the study reviewed the environmental activities of 50 universities ranked highly in terms of their environmental credentials or their environmental science courses. The results are presented and then discussed in terms of how universities can affect material flows, promote sustainability outside of the formal curriculum, and act as catalysts with business. The economic significance of universities provides an appreciable demand for circular products and services. Universities should develop “hidden curriculum” plans to promote improved environmental behaviours of staff and students. Universities can also catalyse a circular economy by working with business to improve eco-effectiveness as well as eco-efficiency. For example, projects should extend the focus from decreasing carbon footprint to achieving carbon positivity, from improving water efficiency to treating wastewater, and from recycling to reverse logistics for repurposing. Pilot projects arising from such work could provide valuable research bases and consultancy opportunities.

As data from manufacturing and digital intelligence become a pervasive feature of our economy, it becomes increasingly important to leverage on this data in the creation of new forms of value. Within emerging concepts such as Industry 4.0 (I4.0) and the Internet of Things (IoT), understanding decision-making and stakeholders’ interaction is important in optimising manufacturing and post-manufacturing processes. Of interest is the post-manufacturing phase for the Rechargeable Energy Storage system, (RESS), a battery system embedded in hybrid and electric automobiles. This research develops a decision-making framework for the RESS component, employing data-driven remanufacturing as the circular approach for implementation. Findings highlight useful manufacturing data employed in remanufacturing for the RESS technology. This study concludes by giving recommendations on how decisions made by stakeholders and their interaction can inform manufacturers on design for remanufacturing.

In a linear economy, a product is manufactured and sold to a customer. Then, little concern is given to what the user actually does with it when they have it. However, in a circular economy where the aim is to circulate products at their highest level of value, the customer’s behaviour can become an important part of the system. Circular design strategies have tended to focus on the physical aspects of a product (e.g., disassembly, material selection), but the design of products and services can also have an influence on user behaviour and, to date, this aspect of circular design has not been fully explored. This project aims to define what key user behaviours are required for circular business models to work and to outline how design can enable these ‘circular behaviours’. This research project consists of a literature review, case study analysis and expert interviews with practitioners. A theoretical framework for designing products and services to encourage circular behaviour is developed. This work provides an initial step towards a better understanding of the user’s role in the transition to a circular economy as well as a preliminary model for how design for behaviour change strategies could be implemented in this context.

Implementing practices for a circular economy transforms the way companies do business, notably in the manufacturing industry. However, a circular economy requires a transformation of both production and consumption systems; the standard approach for creation, fabrication, and commerce of products is challenged. Authors repeatedly call for the development of new proficiencies to attend to system transformations, but these so far have not been described for design and engineering. Given that the design of a product directly influences the way a value chain will be managed, building circular, globally sustainable value chains inevitably signifies a fundamental change in the practice of design. Comprehensive analyses were conducted on case studies from a variety of multinational enterprises that are transforming their product strategies for climate change. Changes in design processes were identified, revealing a growing necessity for industry to employ new proficiencies that support closure of material loops. This paper contributes to existing literature by depicting successful practices being implemented in industry. A variety of new capabilities are key to design for a sustainable future; these range from deeper knowledge of material composition to rich understanding of social behaviour. Resulting from this research, learning goals are proposed to serve as guidance for manufacturing companies seeking to tackle climate change. Conclusions aim to encourage researchers and academics to respond to emerging needs by re-thinking education in design and engineering

Technology-mediated environments are important not only as the location for an increasing proportion of purchases, but also as an even more pervasive part of the purchase journey. While most research into online consumer behavior focuses on attitudes as an antecedent of product choice, this article focuses on an important but hardly explored variable that may be impacted by technology-mediated environments: self-accountability. Laboratory experiments suggest that self-accountability may influence online purchases, but this has not been confirmed in field studies. Furthermore, although this prior work suggests that self-accountability may impact product choice through the elicitation of guilt, the role of positive emotions has not been explored. Using two surveys with online retailers, this paper (a) shows that in a technology-mediated environment, self-accountability influences product choice; (b) proposes and confirms a complementary route for this effect through pride that is stronger than that through guilt; and (c) evidences the relationship between self-accountability and perceived consumer effectiveness. These results show a clear opportunity for digital marketers to encourage self-accountability, to thereby elicit pride and not just guilt, and hence to impact consumer decision making in technology-mediated environments, particularly when choices have sustainability implications.

Energy efficiency is a critical issue for all manufacturing sectors. In the present paper the energy efficiency of UK foundries was assessed. In the context of this research 80 foundries were studied, 60 were contacted and 10 were visited. General energy data were collected using structured questionnaires, interviewing energy managers and process operators. A number of foundries are operating to a good standard, by employing energy managers and regularly auditing; they are in control of their process and working rigorously to improve their efficiency. Simultaneously though, smaller foundries have not adjusted to the new market demands and are not operating in the most energy efficient manner. Important barriers to energy efficiency in these foundries include lack of knowledge on auditing methods, poor knowledge in managing energy consumption, the inefficiency of individual process steps, production disruptions, aging equipment, personnel behavior, inadequate maintenance and lack of investment, automation and research.

The minimization of energy, waste, and emissions in operations are the foremost sustainability goals in industry. The shift from a linear product lifecycle to a circular one is required, along with increased energy efficiency and reduced resource use, to achieve these goals. This paper examines how the use of Re-Distributed Manufacturing (RdM) and a Product-Service System (PSS) approach, while leveraging the latest digital manufacturing technologies, enables the shift to this new economic model. A case study illustrates this new approach and relates it to the shoe manufacturing industry. The ShoeLab case study includes an outline of the business model options supporting this new approach to sustainable production highlighting the circularity that may be achieved in employing RdM and the latest digital manufacturing technologies in the form of 3-D printing. The research conducted indicates that using IDEF0 modelling could help to realize the full potential of RdM such as the manufacturing and transport of products involving less material, energy and waste
