This paper presents challenges in city logistics for circular supply chains of e-e-waste. Efficient e-waste management is one of the strategies to save materials, critical minerals, and precious metals. E-waste collection and recycling have gained attention recently due to lower collection and recycling rates. However, implementing circular urban supply chains is a significant economic transformation that can only work if coordination decisions are solved between the actors involved. On the one hand, this requires the implementation of efficient urban collection technologies, where waste collection companies collaborate with manufacturers, urban waste treatment specialists, and city logistics service providers supported by digital solutions for visibility and planning. On the other hand, it also requires implementing urban and regional ecosystems connected by innovative CO2-neutral circular city logistics systems. These systems must smoothly and sustainably manage the urban and regional flow of resources and data, often at a large scale and with interfaces between industrial processes, private, and public actors. This paper presents future research questions from a city logistics perspective based on a European project aimed at developing a blueprint for systemic solutions for the circularity of plastics from applications of rigid PU foams used as insulation material in refrigerators.

Implementing circular urban supply chains is a major economic transformation that can only work if significant coordination problems between the actors involved are solved. This requires, on the one hand, the implementation of efficient urban collection technologies, where process industries collaborate hand-in-hand with manufacturers and urban waste treatment specialists and are supported by digital solutions. On the other hand, it also requires implementing regional ecosystems connected by innovative CO2-neutral circular city logistics systems smoothly and sustainably managing the regional flow of resources and data, often at large-scale and with interfaces between industrial processes and private and public actors. Develop blueprint for circular urban region This research project aims to develop a blueprint for circular urban regions, including the demonstration of a territorial cross-sectorial, large-scale and sustainable systemic solution for the circularity of high-performance plastics from diverse applications of rigid polyurethane (PU) foams used as insulation material in refrigerators and construction elements. The research project develops a blueprint for regional participative governance using an approach involving multiple actors from the public-, private-, academic-, and financial sectors and civil society (by working in living labs).The focus of the presentation (and paper) is on the control tower elements of the circular urban supply chain and the elements to make the collaboration work.In terms of urban logistics and collection services is to make these materials accessible for downstream sorting and recycling processes for the first time in a sustainable and economically viable way. The project will develop a new way of processing defined waste streams like appliances (refrigerators), to separate chemically recyclable PU from a mixed plastics waste stream.

Recent challenges such like climate, demographic, political, economy and market changes are the foundation for the establishment of the Regional Cooperative Westerkwartier (RCW) in the Northern Netherlands. This RCW is managing a vast range of regional programs and projects developed by multi-stakeholder groups within the region. These stakeholders are representatives of market, public administration, education, research and civil society. All the activities of the cooperative focus on strengthening the regional economy. One of the major programs is the development of a regional food chain (RFC) based on cooperation between small and medium sized enterprises and corporate purchasers. The cooperative is identifying its role within this RFC to develop this chain in an effective way. This article reflects the results of a literature study in the fields of green supply chain management and industrial symbiosis to understand the most important factors of chain development and enterprise symbiosis. Based on these results multiple in-depth interviews and a survey have been conducted. This results in a list of factors, ranked according to their importance for small and medium-sized enterprises. In the role of a RFC-agent the cooperative should focus on creating trust, achieving one overall goal and ensuring clear agreements within the RFC. Surprisingly, the factor “achieving a fair distribution of costs and benefits” throughout the chain is not as important as was expected to be. Based on these ranked factors the role of the RFC-agent has been clarified and an additional circular chain business model can be developed.

In our in-depth case study on two circular business models we found important roles for material scouts and networks. These key partners are essential for establishing circular business models and circular flow of materials. Besides, we diagnose that companies are having difficulties to develop viable value propositions and circular strategies. The paper was presented at NBM Nijmegen 2020 and will be published at a later date

From the article: "ABSTRACT: The research group Supply Chain Redesign in the Built Environment of HU University of Applied Sciences is working on research that combines principles of the circular economy with open source architectural design & urban planning. The aim is finding new ways to re-use demolition waste and recycled materials in small scale urban area developments. And to “democratize” traditional processes in the built environment. Different recent studies have shown the potential benefits, such as a reduction of emissions. In “Hof van Cartesius”, a practical case-study in Utrecht, the ambitions and implications of this approach are being questioned, investigated and tested."

Abstract. In recent years circular economy has become more important for the development of many places including cities. Traditionally, urban development policies have mainly been aiming to improve the socio-economic wellbeing of neighbourhoods. However, technical and ecologic aspects have their effects too and need to go hand in hand. This paper is based on an urban area experiment in the Dutch city of Utrecht. In order to assess urban area developments, typically rather straight-forward quantitative indicators have been used. However, it has proved more complicated to assess multifaceted developments of the area studied in this paper. With the City Model Canvas a multi-layered model is being used to better assess the impact of the urban development being studied. Key findings include that the project studied resulted in more space for companies from the creative industry and the settlement of local ‘circular’ entrepreneurs and start-ups, although it remains unclear to what extent these benefit from each other’s presence. The increase in business activity resulted in more jobs, but it is again unclear whether this led to more social inclusion. From an environmental point of view the project activities resulted in less raw materials being used, although activities and public events bring nuisance to the surrounding neighbourhoods.

Network Applied Design Research (NADR) made an inventory of the current state of Circular Design Research in the Netherlands. In this publication, readers will find a summary of six promising ‘gateways to circularity’ that may serve as entry points for future research initiatives. These six gateways are: Looped Systems; Extension of Useful Lifetime; Servitisation; New Materials and Production Techniques; Information Technology and Digitization; and Creating Public and Industry Awareness. The final chapter offers an outlook into topics that require more profound examination. The NADR hopes that this publication will serve as a starting point for discussions among designers, entrepreneurs, and researchers, with the goal of initiating future collaborative projects. It is the NADR's belief that only through intensive international cooperation, we can contribute to the realization of a sustainable, circular, and habitable world.

Environmental concerns and urbanization pressures are driving demand for more efficient reverse logistics in city environments, where space constraints and dense populations create unique challenges. Polyurethanes (PU), used widely in insulation, electronics, and automotive industries, are integral to circular supply chain discussions due to their low recycling rates. This study emphasizes the challenges of urban reverse logistics for the disposal and collection of refrigerators in countries with different waste management systems. In the paper qualitative and quantitative methods have been applied. Based on the research carried out, it was shown how complex the reverse logistics process is in the city concerning waste such as fridges. It is influenced by, among other things, regulations at EU and national level, cooperation between stakeholders, consumer awareness and education, and real-time access to information on waste.

Our planet’s ecology and society are on a collision course, which manifests due to a contradiction in the assumptions of unlimited material growth fueling the linear economic paradigm. Our closed planetary ecosystem imposes confined amounts of space and a finite extent of resources upon its inhabitants. However, practically all the economic perspectives have been defiantly neglecting these realities, as resources are extracted, used and disposed of reluctantly (Ellen MacArthur Foundation 2015). The circular economy attempts to reconcile the extraction, production and usage of goods and resources with the limited availability of those resources and nature’s regenerative capabilities This perspective entails a shift throughout the supply chain, from material science (e g non-toxic, regenerative biomaterials) to novel logistical systems (e g low-carbon reverse logistics). Because of this, the circular economy is often celebrated for its potential environmental benefits and its usefulness as a blueprint for sustainable development (Ellen MacArthur Foundation 2017). Unfortunately, the promise of the circular economy aiming at enhanced sustainability through restorative intent and design (McDonough & Braungart 2010), is often inhibited by institutional barriers posed by the current linear economy of take, make, use and waste (Ghisellini et al. 2016). Underlying those barriers our cultural paradigm celebrates consumerism, exponential growth and financial benefit instead of human values such as diversity, care and trust. Based on a mapping exercise of the circular economy discourse in the Netherlands and an overview of international (academic) literature (Van den Berg 2020) supplemented with collaborative co-creation sessions, visiting events, conferences, giving talks and classes, we have defined a gap leading to the focus of the Professorship. First, we highlight the importance of a process approach in studying the transition from a linear to a circular economy, which is why we use the verb ‘entrepreneuring’ as it indicates the movement we collectively need to make. The majority of work in the field is based on start-ups and only captures snapshots while longitudinal and transition perspectives - especially of larger companies - are missing (Merli et al. 2019; Geissdoerfer et al. 2018; Bocken et al. 2014). We specifically adopt an entrepreneurship-as-practice lens (Thompson, Verduijn & Gartner 2020), which allows us to trace the doings – as opposed to only the sayings - of organizations involved in circular innovation. Such an approach also enables us to study cross-sector and interfirm collaboration, which is crucial to achieve ecosystem circularity (Raworth 2019). As materials flow between actors in a system, traditional views of ‘a value chain’ slowly make way for an ecosystem or value web perspective on ‘organizing business’. We summarize this first theme as ‘entrepreneurship as social change’ broadening dominant views of what economic activity is and who the main actors are supposed to be (Barinaga 2013; Calás, Smircich & Bourne 2009; Steyaert & Hjorth 2008; Nicholls 2008). Second, within the Circular Business Professorship value is a big word in two ways. First of all, we believe that a transition to a circular economy is not just a transition of materials, nor technologies - it is most of all a transition of values We are interested in how people can explore their own agency in transitioning to a circular economy thereby aligning their personal values with the values of the organization and the larger system they are a part of Second, while circularity is a broad concept that can be approached through different lenses, the way in which things are valued and how value is created and extracted lies at the heart of the transition (Mazzucato 2018). If we don’t understand value as collectively crafted it will be very hard to change things, which is why we specifically focus on multiplicity and co-creation in the process of reclaiming value, originating from an ethics of care Third, sustainability efforts are often concerned with optimization of the current – linear – system by means of ecoefficient practices that are a bit ‘less bad’; using ’less resources’, causing ‘less pollution’ and ‘having less negative impact’. In contrast, eco-effective practices are inherently good, departing from the notion of abundance: circular thinking celebrates the abundance of nature’s regenerative capacities as well as the abundance of our imagination to envision new realities (Ellen MacArthur Foundation 2015). Instead of exploiting natural resources, we should look closely in order to learn how we can build resilient self-sustaining ecosystems like the ones we find in nature. We are in need of rediscovering our profound connection with and appreciation of nature, which requires us to move beyond the cognitive and employ an aesthetic perspective of sustainability This perspective informs our approach to innovating education: aesthetics can support deep sustainability learning (Ivanaj, Poldner & Shrivastava 2014) and contribute to facilitating the circular change makers of the future. The current linear economy has driven our planet’s ecology and society towards a collision course and it is really now or never: if we don’t alter the course towards a circular economy today, then when? When will it become urgent enough for us to take action? Which disaster is needed for us to wake up? We desperately need substitutes for the current neo-liberal paradigm, which underlies our linear society and prevents us from becoming an economy of well-being In Entrepreneuring a regenerative society I propose three research themes – ‘entrepreneurship as social change’, ‘reclaiming value’ and ‘the aesthetics of sustainability’ – as alternative ways of embracing, studying and co-creating such a novel reality.

From a circular standpoint it is interesting to reuse as much as possible construction and demolition waste (CDW) into new building projects. In most cases CDW will not be directly reusable and will need to be processed and stored first. In order to turn this into a successful business case CDW will need to be reused on a large scale. In this paper we present the concept of a centralized and coordinated location in the City of Utrecht where construction and demolition waste is collected, sorted, worked, stored for reuse, or shipped elsewhere for further processing in renewed materials. This has expected advantages for the amount of material reuse, financial advantages for firms and clients, generating employability in the logistics and processing of materials, optimizing the transport and distribution of materials through the city, and thus the reduction of emissions and congestion. In the paper we explore the local facility of a Circular Hub, and the potential effects on circular reuse, and other effects within the City of Utrecht.
