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.
What are the circular possibilities for materials and productsavailable in the Griffiersveld pilot and how can this informationbe presented? Interviews with stakeholders have led to a list ofrequirements for the material passports and what informationthey should include. Existing and experimental materialpassports have been collected and analysed to see whetherthey meet the requirements. The construction materials on siteare identified and circular possibilities of these materials arelisted. Finally an advice is given for the municipality ofApeldoorn for a circular renovation approach.
We aim to understand the interaction between shifting organizational field logics and field actors’ responses to reconcile logic plurality and maintain legitimacy through business model innovation. Drawing on a multimethod, longitudinal field study in the fashion industry, we traced how de novo and incumbent firms integrate circular logics in business models (for sustainability) and uncover how productive tensions in field logics lead to experimental spaces for business model innovation. Our findings showed a shift in the discourse on circular logic that diverted attention and resources from materials innovation (e.g. recycling) to business model innovation (e.g. circular business models). By juxtaposing the degree of field logic tension and the degree of business model innovation, we derive four types of business model hybridization responses that actors engaged in to maintain legitimacy – constrained, limited, integrated, and expanded. Our study generates new insights on business models for sustainability as vehicles for organizational field change.
Recycling of plastics plays an important role to reach a climate neutral industry. To come to a sustainable circular use of materials, it is important that recycled plastics can be used for comparable (or ugraded) applications as their original use. QuinLyte innovated a material that can reach this goal. SmartAgain® is a material that is obtained by recycling of high-barrier multilayer films and which maintains its properties after mechanical recycling. It opens the door for many applications, of which the production of a scoliosis brace is a typical example from the medical field. Scoliosis is a sideways curvature of the spine and wearing an orthopedic brace is the common non-invasive treatment to reduce the likelihood of spinal fusion surgery later. The traditional way to make such brace is inaccurate, messy, time- and money-consuming. Because of its nearly unlimited design freedom, 3D FDM-printing is regarded as the ultimate sustainable technique for producing such brace. From a materials point of view, SmartAgain® has the good fit with the mechanical property requirements of scoliosis braces. However, its fast crystallization rate often plays against the FDM-printing process, for example can cause poor layer-layer adhesion. Only when this problem is solved, a reliable brace which is strong, tough, and light weight could be printed via FDM-printing. Zuyd University of Applied Science has, in close collaboration with Maastricht University, built thorough knowledge on tuning crystallization kinetics with the temperature development during printing, resulting in printed products with improved layer-layer adhesion. Because of this knowledge and experience on developing materials for 3D printing, QuinLyte contacted Zuyd to develop a strategy for printing a wearable scoliosis brace of SmartAgain®. In the future a range of other tailor-made products can be envisioned. Thus, the project is in line with the GoChem-themes: raw materials from recycling, 3D printing and upcycling.
Verschillende maatschappelijke veranderingen dwingen de bouwbranche tot innovaties. Ondanks de potentie op het vlak van circulariteit en duurzaamheid van 3D-printen met kunststoffen kent deze technologie nog nauwelijks toepassingen in de bouw. Redenen hiervoor zijn achterblijvende materiaaleigenschappen en het verschil in cultuur tussen de bouwwereld en kunststofverwerkende industrie. Het bedrijf Phidias, richt zich op innovatieve en creatieve vastgoedconcepten. Samen met Zuyd Hogeschool (Zuyd) willen zij onderzoek doen naar het printen van bouwelementen waarbij de meerwaarde van 3D-printen wordt gezien in het combineren van materiaaleigenschappen. Zuyd heeft afgelopen jaren veel onderzoek gedaan naar het ontwikkelen van materialen voor 3D-printen (o.a. 2014-01-96 PRO). De volgende fase is de opgedane kennis toe te passen voor specifieke applicaties, in dit geval om de vraag van het MKB bedrijf Phidias te beantwoorden. Vanuit een ander MKB-bedrijf, MaukCC, ontwikkelaar van 3D printers, komt de vraag om de afstemming tussen materialen en hardware te optimaliseren. De combinatie van beide vragen uit het werkveld en de expertise bij Zuyd heeft geleid tot dit projectvoorstel. In deze pilotstudie ligt de focus voornamelijk op het 3D printen van één specifiek bouwkundig element met meerdere eigenschappen (bouwfysisch en constructief). De combinatie van eigenschappen wordt verkregen door gebruik te maken van twee (biobased) kunststoffen waarbij tevens een variatie wordt aangebracht in de geprinte structuren. Op deze manier kunnen grondstoffen worden gespaard. Het onderzoek sluit aan bij twee zwaartepunten van Zuyd, namelijk “Transitie naar een duurzaam gebouwde omgeving” en “Life science & materials”. De interdisciplinaire aanpak, op het grensvlak van de lectoraten “Material Sciences” (Gino van Strydonck) en “Sustainable Energy in the Built Environment” (Zeger Vroon) staat garant voor innovatief onderzoek. Integratie van onderwijs en onderzoek vindt plaats door studenten samen met een coach (docent) en ervaren professional aan dit onderzoek te laten werken in Communities for Development (CfD’s).
Microbes like bacteria and fungi can grow on almost everything, including e.g. on a music CD made of aluminum and polycarbonate. How? By producing an optimal mixture of effective enzymes that degrade the material on which the microbes thrive. In this project we want to find and characterize microbes that have the ability to digest one of the most commercially successful but at the same time hard-to-degrade materials: furan-based bio-composite resin. To help the microbes to degrade this recalcitrant material, we first must open up the complex resin structure by using (mild) acidification, grinding, and/or UV light. Thus, with this project we aim to find an effective and sustainable way to safely and effectively dispose and recycle used bio-composite resins. Our findings will help to increase the circularity of bio-composite materials and as such decrease the environmental waste pressure.
