Confronted by more and more global sustainabilityrelated challenges, society is increasingly aiming for a circular economy. Wouldn’t it be ideal if we could contribute to an economic model with closed loops, where products and materials that are at the end of their functional life are reused in new products and systems? As the Netherlands aims to have a fully circular economy (i.e., zero net waste) by 2050, circularity is also a critical theme for the Amsterdam Metropolitan Area. ‘Circular City’ is one of the main urban challenges of the Urban Technology research programme of the Amsterdam University of Applied Sciences (AUAS). Its chair of Circular Design & Business and its research group on Digital Production collaborate with companies, lecturers and students on a range of applied research projects in order to advance the knowledge around circular design and business model strategies making use of digital production to encourage the local reuse of discarded urban materials. Amsterdam ArenA, home base of the Ajax football team and a major concert and events venue, is replacing all stadium seats in the run-up to the European Football Championship in 2020 (UEFA Euro 2020), and wishes to do so in a socially responsible manner. With that purpose, Amsterdam ArenA engaged the expertise of the Urban Technology research programme at the AUAS to study the viability reusing the old seats in a circular manner. The research started from the assumption that these discarded seats not only form a large and relatively homogeneous waste stream, but also have an emotional value that can potentially raise their economic value, beyond that of the material alone. For the AUAS this was an important case study, because the Amsterdam ArenA aspires to be a stage for sustainable innovations, reduce its environmental impact and stimulate the local economy. This project could serve as an example for other stadiums and public buildings with substantial waste streams on how to handle discarded products, and rethink how they can prevent waste in the future. With this mission, the AUAS lined up a team of experts on circular design, digital production, business modelling and impact studies to carry out a comprehensive multi-disciplinary study.

This paper presents the results of the research project ‘Going Eco, Going Dutch’ (2015- 2017), which investigated the production, design and branding of fashion textiles made from locally produced hemp fibers in the Netherlands. For fashion labels and designers it is often difficult to scrutinize the production of textile fabrics manufactured in non-European countries due to physical distance and, often, non-transparency. At the same time, many designers and established fashion brands increasingly search for sustainable textiles that could be recycled or upcycled after being used by consumers. For the project ‘Going Eco, Going Dutch’, local textile manufacturers and fashion brands closely collaborated to explore how to develop fashionable textiles made from locally produced hemp – from the very first fiber to the final branding of the fashion product. In addition to the technical insights on the production of hemp, this paper will present and highlight the importance of the visual identity of the textiles, which was created by using Dutch traditional crafts – suggesting that this should be understood in terms of Kristine Harper’s ‘aesthetic sustainability’ (2017) as an essential design strategy. In addition, this paper will reflect on the importance of storytelling by focusing on locality and transparency, and on creating an emotional bond and connection between producer, product and consumer. This paper will argue that this form of ‘emotional durability’ (Chapman, 2005, 2009) is essential to both design and branding strategies. Moreover, this paper will critically reflect on the performance of Dutchness – Dutch national identity – through these locally produced fibers, textiles and fashion products.

Het Urban Technology onderzoeksprogrammavan de Hogeschool van Amsterdam (HvA) doet praktijkgericht onderzoek voor de omschakeling naar eencirculaire stad. Eén van de factoren die hierbij een rol spelen is hoe producten circulair ontworpen kunnenworden. In een aantal onderzoeksprojecten wordt door de HvA specifiek gekeken naar het gebruik van lokalereststromen om circulaire producten te ontwerpen. Onder meer aan de hand van een wel heel bijzonderereststroom: de in 2017 afgedankte stadionstoelen van de Amsterdam ArenA. In Product #5 / 2017 en Product#2 / 2018 verschenen de eerste twee delen waarin de achtergrond van dit onderzoek is besproken en waarinsuggesties voor nieuwe stoelontwerpen op basis van upcycling en recycling gedaan zijn.In dit derde en laatste deel richten we ons op de consument. We gaan in op de vraag hoe circulaireproducten door de consument gewaardeerd worden en welke rol de herkenbaarheid
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.
In het project CW4.0 onderzoeken MKB’ers uit de houtindustrie en Smart Industry samen met de Hogeschool van Amsterdam (HvA), kennispartners TNO, HMC en Bouwlab R&Do en partners in hospitality hoe zinvolle toepassingen te maken van resthout, met behulp van Industry 4.0-principes. Hoogwaardig hout blijft momenteel ongebruikt, omdat het te arbeids-intensief is grote hoeveelheden ongelijkmatige stukken hout van verschillende grootte en houtsoort te verwerken. Waardevol resthout wordt zo waardeloos afval, tegen de principes van de circulaire economie in. CW4.0 richt zich op de ontwikkeling van geautomatiseerde processen voor houtverwerking gebaseerd op Industry 4.0 technologieën - met behulp van digitale ontwerptools en industriële robots. Uit eerdere projecten van HvA en partners is gebleken dat deze processen het gebruik van resthout levensvatbaar kunnen maken, in het bijzonder voor toepassingen in de hospitality sector, bijvoorbeeld voor receptiebalies, hotelmeubilair en interieurdelen. CW4.0 wordt dan ook uitgevoerd in samenwerking met hospitality-ontwerpers en hotelketels. Het onderzoek concentreert zich op 1) het creëren van een digital twin (=digitale kopie van een beoogd object of proces, om dit te onderzoeken zonder het eerst te hoeven bouwen) van een ‘upcycle houtfabriek’; 2) het realiseren en beproeven van secties van de fabriek; 3) het ontwerpen en prototypen van hospitality toepassingen en 4) het evalueren van de business case van deze toepassingen en de fabriek in het algemeen. Na afloop is er kennis beschikbaar voor houtindustrie om afval te verminderen, voor Smart Industry om hun digitale technologieën toe te passen voor upcycling van materialen, en voor horecapartners om waardevolle toepassingen te creëren van resthout. Het project is een belangrijke stap in de opschaling van industriële robotproductie met circulaire materialen. Het legt een nieuwe, belangrijke verbinding tussen Smart Industry en de circulaire transitie, gericht op het aanpakken van urgente maatschappelijke uitdagingen verband houdend met materiële schaarste en de mondiale milieucrisis.
In Amsterdam's neighbourhoods, much of the waste that is disposed has the potential of becoming something else by means of recycling or upcycling. Zero Waste lab –which is part of the organization De Gezonde Stad- is a place where inhabitants can bring their own separated waste in exchange for value coins. Now, Zero Waste Lab now wants to take this a step forward and further develop their own project: from recycling to upcycling waste. In this endeavour, HvA will collaborate by researching the possibilities for upcycling a local waste stream by means of digital production pro-cesses, as well as ways of involving the neighbourhood. Because it is of vital importance for the project not only to be technically possible, but also scalable and economically feasible, Zero Waste Lab and HvA have asked for partnership to the company Verdraaid Goed. This partnership and specific case study, presented here as ‘Wood for the neighborhood’ can be summa-rized in four main goals: • (Production) Explore the design and manufacturing possibilities of using digital production to upcycle a local wood waste stream (with an industrial robotic arm) • (Design) Show how explorative research, when carried on from the beginning of the de-sign process, can bring great added value to the development of project concepts. • (Social) Demonstrate that involving stakeholders early in the process of reusing and de-signing with waste materials can shape the future in new directions • (All three) Highlight how this case study is relevant and fits the principles of the circular economy
