A circular economy perspective embraces a systemic, cradle-to-cradle notion that everything is designed to be reused as long as possible and then recaptured and repurposed when reuse is no longer possible. Designing for a circular economy ecosystem requires a holistic, integrative viewpoint, spanning all aspects of design and development and considering many supply chain actors, far beyond that of traditional supply chains. This edited book adopts a biomimetic lens, highlighting the need for cross-industry flows and need for different actors (beyond producers and consumers) in circular value cycles. Enablers such as incentives and/or legislation are also discussed. While biomimicry provides the structure for organizing this book, individual chapters build on other theoretical lenses and concepts, such as stakeholder theory, etc. The intent is to move beyond a dyadic (buyer–supplier) view, embracing a holistic network or ecosystem view, to consider a cross-industry system perspective, where there is a diversity of actors (covering four actor groups: producers, consumers, scavengers, and decomposers) needed for a working ecosystem. This edited book offers a comprehensive overview of system components and actors, including how the circular economy adds value, the role of producers and consumers, the spectrum of recovery possibilities to return products back to the consumption supply chain, and the essential role of information management.

The circular economy is a system that aims to conserve resources at every level for as long as possible with a minimization of waste. The core concept of the circular economy is to improve resource efficiency and prevent valuable materials from leaking out of the system. Better use of increasingly scarce resources can provide both economic and environmental benefits. When excess inventory, returned products, and end-of-life products are disposed of improperly, unnecessary waste is created, often with a detrimental impact to the environment. An effective system must exist to facilitate the proper handling of these products, and secondary markets are a crucial component in this system. In this chapter, we discuss the secondary markets’ role as an important mechanism for achieving a circular economy.

The earth’s carrying capacity cannot withstand the pace of consumption resulting from current economic models, mainly the linear economy (LE) built on a throwaway culture. In the last few decades, the concept of a circular economy (CE), aiming to design waste out of the economy and mimic ecosystems, emerged as a strong alternative to LE. Being at the heart of the economic landscape, supply chains (SCs) need to respond to the necessary shift to CE. In so doing, the planning and execution of circular supply chains (CSCs) require a broader comprehension of CE and more sophisticated and large-scale analytical decision models. This chapter surveys extant literature on available best practices and quantitative models for sustainable supply chains (SSCs) and offers a new definition of CSC. Mapping on the knowledge extracted from this classification, potential gaps and strengths in the literature are identified. Key research papers on the “closed-loop” and “open-loop” ends of CSCs are highlighted. Challenges in developing CSC performance indicators and prescriptive models are emphasized.

This chapter shows how different recycling locations influence closed-loop supply chain (CLSC) cost and carbon dioxide equivalents (CO₂e), as well as reveal competitive recycling and manufacturing locations, including relevant distance- and location-related factors, for achieving very low cost and CO₂e CLSCs supporting circular economy. Exploratory data analysis is used to analyze results from simulations based on empirical data and market rates relating to textile and clothing CLSCs. The results show that most very low-cost and CO₂e CLSCs consist of fabric and garment manufacturing located at the same or nearby locations, and whose labor costs and electricity CO₂e are low, whether fiber recycling facilities are located in proximity to used garment sorting facilities or not. Scenario and sensitivity analyses of important cost and CO₂e factors for recycling location competitiveness reveal that increasing used garment prices makes locations with high import duties lose competitiveness, and that varying water freight CO₂e changes comparative location competitiveness.

The current rates of population growth necessitate the need for more sustainable food production. The breeding of insects could be a possibility. Since the turn of the millennium, there has been a clear increase in the interest in breeding insects in Europe. The main products from insect farms are insects and proteins, but insect farms also produce insect frass (insect feces). Due to its high nutritional content, insect frass has a great potential to be upcycled for the production of fertilizers, compost material, soil improvers, or growth enhancers. The use of insect frass as fertilizer can help limit the use of agrochemicals. By reintroducing valuable material into the food production chain, the land application of insect frass is consistent with the circular economy’s principles. Before insect frass can be introduced to the market as a fertilizer, sanitizing treatment is needed in order to eliminate possible microorganisms that are harmful to health. In Europe, no legislation specifically developed for the use of insect frass as fertilizer has been formulated yet. Due to the absence of such European Union (EU) legislation, the possibilities of upcycling frass remain relatively limited. In this case study, focus is on the regulatory barriers of upcycling frass in Denmark.

Blanc de Gris (BDG) is producing oyster mushrooms from organic waste (coffee grounds and spent grains) in Downtown Montreal. This project brought the two co-founders of this circular enterprise into a challenging journey. Based on an ethnographic account of BDG, including observations, interviews, and a four-month internship into the business, this chapter highlights the difficulties of creating an industrial symbiosis. From gaining legitimacy among their peers and bankers to facing operational problems, this chapter outlines the network’s resilience behind this story. This chapter ends by discussing the case in regard to the challenges related to the emergence of circular business models, identified by a report from the Organisation for Economic Co-operation and Development (OECD).

This case study shows how Osklen, a 30-year-old fashion brand in Brazil that focuses on Brazilianness and sustainability, has been facing challenges in the last 10 years pioneering the adoption of recycled cotton in its products. By taking the lens of biomimicry and supply networks that encompass vertical, horizontal, and diagonal ties, the case exposes how the weak links in the transition to circular fashion limit advancements. In a field such as sustainability where lack of transparency prevails and there is decoupling between practices and communication, consumers are often unaware of what is being done behind the scenes, and pioneer fashion brands may not benefit from sustainable and circular fashions. Besides the challenges at the consumer front, the shift to circular fashion is hindered by having scavengers as the weak link in the supply network given the lack of financial incentives, excessive informality, and misguided marketing from larger brands.

Overconsumption of resources has become a global issue. To deal with resource depletion and mitigate these impending crises, the circular economy (CE) holds some promise. A wide range of performance measurements for CE have emerged over the years. However, with increasing complexity of supply chains, appropriate and potentially new performance measurements are needed for effective CE management. Blockchain is an innovative technology that may advance CE development. This chapter provides an overview of the potential linkages between blockchain technology and CE from sustainability perspectives – the specific focus will be on the performance measurement of reverse logistics activities. One of the main findings indicates that both blockchain and CE performance measurements – especially reverse logistics processes – are still evolving in both theory and practical developments. Future directions with a critical analysis including research and theoretical applications will conclude this chapter.

This chapter empirically investigates the main drivers of the circular economy (CE) and sustainable development (SD) of European countries. The European Union (EU) legislation imposes equal rules for the members who should be followed to achieve CE and SD. This chapter gives a critical overview of the related literature on this topic. The second part focuses on measuring the efficiency of EU countries in achieving CE and SD via a nonparametric approach. Furthermore, the results from the efficiency evaluation are used as a dependent variable in determining which economic, social, institutional, and other factors have the greatest influence on CE and SD achievements. The nonparametric approach consists of selected models of data envelopment analysis (DEA), as this is a methodology useful in constructing a ranking system based on selected criteria. The results indicate that on average, the most efficient countries were (besides Malta and Luxembourg) the Netherlands, Poland, Germany, Sweden, Denmark, France, and the United Kingdom. The worst performing ones were Cyprus, Spain, Greece, Belgium, Portugal, and Croatia. The second part of the research indicates that the resource production and corruption perception index has the greatest effect on the efficiency scores, followed by education attainment. The research and development (R&D) variable is not significant in the observed sample. Based on these results, specific policy recommendations are given at the end of this chapter.
