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

Upcycling has been embraced by circular economy enthusiasts, policy-makers and collaborative initiatives across Europe. Early studies describe upcycling as a concept aimed at resource conservation by keeping products, components and materials at their highest potential value across consecutive product lifecycles, with zero-negative or even potential positive impact on the natural environment. Similarly, more recent literature on the circular economy views upcycling as a strategy to slow and close resource cycles through product life-extension approaches, such as reuse, repair, refurbishment, remanufacturing and repurpose. With growing environmental concerns, upcycling has become a re-emerging theme in literature and practice. Cities offer opportunities for an increasing number of upcycling initiatives, but little is known about what manifestations of upcycling occur specifically in urban areas or how these urban upcycling initiatives emerge. For example, so-called Urban Resource Centers seek to tackle challenges in urban solid waste management by encouraging entrepreneurs to create value from local waste streams. Therefore, our objective is to address this literature gap and explore manifestations of upcycling in a city context by means of qualitative research, following a case-study approach based on data collected from research archives and 17 preliminary interviews with entrepreneurs and experts in urban upcycling of furniture and interior design products. This study contributes to a structured overview of urban upcycling initiatives and the internal and external factors that drive entrepreneurial initiatives and development. Future work will build on this study to make urban upcycling initiatives more widespread and impactful to deliver on their environmental and social goals.

This PD project aims to gather new knowledge through artistic and participatory design research within neighbourhoods for possible ways of addressing and understanding the avoidance and numbness caused by feelings of vulnerability, discomfort and pain associated with eco-anxiety and chronic fear of environmental doom. The project will include artistic production and suitable forms of fieldwork. The objectives of the PD are to find answers to the practice problem of society which call for art that sensitises, makes aware and helps initiate behavioural change around the consequences of climate change. Rather than visualize future sea levels directly, it will seek to engage with climate change in a metaphorical and poetic way. Neither a doom nor an overly techno-optimistic scenario seem useful to understand the complexity of flood risk management or the dangers of flooding. By challenging both perspectives with artistic means, this research hopes to counter eco-anxiety and create a sense of open thought and susceptibility to new ideas, feelings and chains of thought. Animation and humour, are possible ingredients. The objective is to find and create multiple Dutch water stories, not just one. To achieve this, it is necessary to develop new methods for selecting and repurposing existing impactful stories and strong images. Citizens and students will be included to do so via fieldwork. In addition, archival materials will be used. Archives serve as a repository for memory recollection and reuse, selecting material from the audiovisual archive of the Institute of Sound & Vision will be a crucial part of the creative work which will include two films and accompanying music.
Verduurzaming van de chemische en landbouwsector is essentieel om klimaat- en circulaire doelstellingen te halen. Eén van de mogelijkheden om de chemische sector te vergroenen is om hernieuwbare grondstoffen als ‘feedstock’ voor productie te gebruiken. Biopolymeren die gemaakt worden uit hernieuwbare grondstoffen zijn een interessant groen alternatief voor fossiele plastics. Een veelbelovende groep ‘biobased plastics’ zijn polyhydroxyalkanoaten (PHA). PHAs worden door micro-organismen geproduceerd en kunnen verschillende samenstellingen hebben die de eigenschappen van dit materiaal beïnvloeden. Hierdoor zijn PHA's, blends van PHA en andere biobased materialen voor vele toepassingen geschikt te maken en derhalve een serieuze uitdager van fossiele plastics. Zodra deze biobased producten aan het einde van hun gebruikersfase komen, of als single-use materiaal in bijvoorbeeld de agrarische sector worden toegepast, is het belangrijk naast de mogelijkheden voor hergebruik en recycling inzicht te hebben in de snelheid en volledigheid van de biologische afbraak. In het voorgestelde KIEM-onderzoek wordt biologische afbraak middels industriële en kleinschalige compostering en in natuurlijke milieus bepaald. Onder verschillende omstandigheden, zoals in mariene, estuariene en zoetwatermilieus, en in verschillende bodemtypen zoals zand, klei en veenbodems wordt vastgesteld of effectieve afbraak plaatsvindt. Afbraak tot bouwstenen voor nieuwe polymeren of volledige mineralisatie, de snelheid daarvan en of mogelijk sprake is van vorming van microplastics wordt onderzocht. Stimuleren van biologische afbraak door bio-augmentatie wordt eveneens onderzocht. Een succesvol project draagt bij aan het verbeteren van de business case van zowel producenten van biobased polymeren (Paques Biomaterials) als van de maakindustrie die producten maken van deze groene ‘plastics’ (Maan Biobased Products; Happy Cups). Het projectresultaat geeft aanwijzingen over de impact die het onvermijdelijke PHA--zwerfafval zal hebben op het milieu en hoe deze impact zich verhoudt tot die van fossiel-gebaseerd zwerfplastic. Daarnaast vormt dit project ook de basis voor een nieuwe business case voor gecontroleerde end-of-life verwerkingsmethodieken.
Circularity represents an innovative approach to sustainability, aiming to transition from linear systems to cyclical ones by minimizing waste and optimizing resource utilization. Key to this concept is the repurposing of waste into valuable resources, which not only reduces environmental impact but also fosters innovation and produces further value. By utilizing their own waste, organizations can not only decrease their ecological footprint but also promote the development of materials with enhanced circularity thus mitigating environmental harm. Embracing circular practices provides a tangible pathway towards harmonizing human activities with the natural world, nurturing a regenerative global ecosystem. In a concerted effort to tackle biomass waste generated from JvEsch's operations, a strategic partnership with MNEXT is forged. This collaboration endeavours not only to replace unsustainable materials but also to enhance operational efficiency. Central to this initiative is a one-year research feasibility project which focuses on upcycling JvEsch’s biomass waste into valuable products for use in their business model. By examining JvEsch's waste streams, opportunities for the production of alternative materials were being explored. Among these materials, mycelium biocomposites (MBCs) emerge as a promising option for waste reduction and material innovation. The primary objective of this project is to explore the viability of manufacturing and utilizing MBC plant pots using JvEsch's waste. Unlike conventional pots, these innovative alternatives eliminate the need for removal before planting. Through replacing traditional plastic pots commonly used in the industry, the investigation aims to practically demonstrate the transformative potential of circularity in waste management and material production within an organization.
