In response to the pressing need for effective implementation of the Circular Economy (CE), this research introduces a comprehensive theoretical framework for CE roadmapping. This study addresses the prevalent issue of fragmented and inconsistent CE strategies that often hinder the successful translation of long-term goals into achievable KPIs. Through a carefully designed methodology, this framework incorporates strategic management, systems thinking, sustainability science, and other disciplines, providing a structured approach to navigating the complexities of long-term planning for CE. The foundation for this framework is laid through an extensive review of the literature, which identifies theoretical gaps and guides its development. Practical insights are gained through an examination of various CE roadmaps, including sectoral, municipal, national, and regional strategies, thereby enhancing this framework's applicability and robustness. This research highlights substantial variations in current CE roadmapping methods, emphasizing the need for a standardized approach. While acknowledging limitations due to the diverse contexts of the case studies, this study offers significant implications for policymakers, business leaders, and sustainability practitioners by presenting a versatile tool for strategic CE planning. Its interdisciplinary construction mirrors the multifaceted nature of CE, rendering it exceptionally adaptable across various disciplines and levels, reflecting the diverse reality of CE applications.

Experimentation with, and the implementation of, circular business models (CBMs) has gained rapid traction within the textiles and fashion industry over the last five years. Substitution of virgin materials with bioderived alternatives, extending the lifecycle of garments through resale, and rental services and the recycling or upcycling of garments are some of the strategies being used to reduce the 1.2 billion tonnes of greenhouse gas emissions and 92 million tonnes of waste associated with the sector in 2017. However, whilst CBMs demonstrate environmental and economic benefits, low consumer acceptance is considered by business professionals and policymakers to be one of the main barriers to the transition towards a circular economy. Digitisation is widely acknowledged as a catalyst for innovation in many sectors and digital technologies are driving new ways to exchange and share goods and services, enabling companies to match the supply, and demand for, otherwise underused assets and products. Online platforms, in particular, have played a crucial role in driving the growth of used goods and resale in other consumer goods markets, such as consumer technology. A mixed methods approach, including a review of 40 organisations operating second hand fashion models, a consumer survey of over 1200 respondents and in-depth interviews with 10 organisations operating second hand fashion models, is adopted to reveal (a) the barriers to consumer acceptance of reuse models in the fashion industry, and (b) how digital technologies can overcome these barriers. Findings highlight the significant progress that organisations have made in using digitalisation, including data analytics, algorithms, digital platforms, advanced product imagery and data informed customer communications, to address barriers associated with convenience, hygiene, trust and security. Furthermore, the study identifies opportunities for the development of more sophisticated digital technologies to support increased transparency and address concerns associated with the quality, authenticity and sourcing of materials. Positioned at the interface of digitisation and consumer acceptance of circular business models, this study makes an important contribution to understanding consumer barriers and how to address them and concludes with a set of recommendations for practitioners.

Circular economy is an upward trending notion that has drawn worldwide attention of policymakers, industry administrators, environmentalist as well as academic researchers. Though there are several tools developed for monitoring the material recovery, a very few number of research have been conducted to integrate circular economy principles with end-of-life (EOL) management strategies. This paper proposes an EOL-driven circular economy framework for the management of materials flow so as to extend the lifetime of materials through improved durability as well as to provide more social, economic and environmental benefits through less material waste. A case study from the agricultural waste industry is presented in order to test the model and validate its performance. The results show that the proposed framework has a good potential for small and medium enterprises (SME) advances. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The article discusses the use of the business model IDEF (Icam DEFinition for Function Modelling) for re-distributed manufacturing (RdM) within a circular and sustainable production system.

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.

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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.
