The urgency for developing a circular economy is growing, and more and more companies and organisations are concerned with the importance of adapting their business to fit a changing economy. However, many analyses on the circular economy are still rather abstract and there is a lack of understanding about what circularity would mean for specific industries. This insufficient insight especially seems to be apparent in the building and construction sector. Besides, the building and construction sector is responsible for a major part of energy use and emissions. To tackle the issue of insufficient insight into the business consequences of circular developments, further research is necessary. Therefore, we propose to collaborate on a research project that aims to provide a more detailed level of analysis. The goal is to identify drivers and barriers to make better use of materials in the building and construction sector. This further research would benefit from an international collaboration between universities of applied sciences and industry from different European countries. An additional benefit of the applied orientation would be the relevance for professional education programmes.

Organizations are currently facing substantial challenges regarding becoming circular by 2050 – also referred to as Circular Economy (CE). Subsequently, increasing complexity on all organizational levels creates uncertainty about respective organizational and technological capabilities and adequate strategies to develop these capabilities. Organizations are struggling in picking up the CE ambitions and answering the what’s in it for me question. Scholars are developing models and frameworks to enable organizations to measure CE performance. Over 125 assessment methods are available for micro level assessment – measuring up to 365 different metrics. Moreover, extant literature is available presenting barriers and opportunities for CE transformation focusing on industry, sector, region, etc. And, although a more holistic perspective is required to become circular mature, this is currently lacking. In this paper we present a multi-methodology view on approaches and how they are used (or not). Our main goal is to extend the existing body of knowledge with an eye on applicability and research directions to untie the Gordian knot of measuring circularity.

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.
“Empowering learners to create a sustainable future” This is the mission of Centre of Expertise Mission-Zero at The Hague University of Applied Sciences (THUAS). The postdoc candidate will expand the existing knowledge on biomimicry, which she teaches and researches, as a strategy to fulfil the mission of Mission-Zero. We know when tackling a design challenge, teams have difficulties sifting through the mass of information they encounter. The candidate aims to recognize the value of systematic biomimicry, leading the way towards the ecosystems services we need tomorrow (Pedersen Zari, 2017). Globally, biomimicry demonstrates strategies contributing to solving global challenges such as Urban Heat Islands (UHI) and human interferences, rethinking how climate and circular challenges are approached. Examples like Eastgate building (Pearce, 2016) have demonstrated successes in the field. While biomimicry offers guidelines and methodology, there is insufficient research on complex problem solving that systems-thinking requires. Our research question: Which factors are needed to help (novice) professionals initiate systems-thinking methods as part of their strategy? A solution should enable them to approach challenges in a systems-thinking manner just like nature does, to regenerate and resume projects. Our focus lies with challenges in two industries with many unsustainable practices and where a sizeable impact is possible: the built environment (Circularity Gap, 2021) and fashion (Joung, 2014). Mission Zero has identified a high demand for Biomimicry in these industries. This critical approach: 1) studies existing biomimetic tools, testing and defining gaps; 2) identifies needs of educators and professionals during and after an inter-disciplinary minor at The Hague University; and, 3) translates findings into shareable best practices through publications of results. Findings will be implemented into tangible engaging tools for educational and professional settings. Knowledge will be inclusive and disseminated to large audiences by focusing on communication through social media and intervention conferences.
Nederland wil in 2050 een circulaire economie zijn. Een economie zonder afval, waarbij alles draait op herbruikbare grondstoffen. Het zuiniger en slimmer omgaan met grondstoffen is ook voor de textielbranche van belang. De meest gebruikte en bekende hernieuwbare plantaardige grondstof voor de textielindustrie is katoen. De huidige niet-circulaire productie en toepassingen van katoen hebben vergaande negatieve impact op mens en milieu. De gebruikersduur van kleding wordt steeds korter en afgedankte kleding wordt laagwaardig verwerkt om uiteindelijk alsnog te worden verbrand. Zowel het economische als duurzame verbeterpotentieel voor circulair textiel is dan ook enorm. De kwaliteit van katoen vermindert met iedere (mechanische) recyclingstap omdat de vezellengte steeds korter wordt. De uitdaging is om meermaals te recycling waarbij in iedere recyclestap waarde wordt behouden en gecreëerd. Als uiteindelijke stap wordt nagestreefd de grondstof veilig terug te laten keren naar de biosfeer als voedingsmiddel waarna een nieuwe cascade kan beginnen: een kringloop in de vorm van regeneratieve cascades. Om dit te realiseren moet de hele keten samenwerken in een transparant systeem waarbij stakeholders meervoudige waarde in balans ontwikkelen, zodat geen partij in de keten wordt benadeeld. Organisaties worstelen met deze veranderende rollen en zoeken nieuwe bedrijfsmodellen, waarin herstel en volhoudbaarheid boven oneindige groei en uitputting staan. In dit project werken Nederlandse bedrijven (met name MKB) uit de gehele textielketen samen met Indiase bedrijven om de werking van een katoencascade -een regeneratief, circulair systeem van katoenzaad tot worteldoek- te onderzoeken en op te tekenen. Een interdisciplinaire benadering is hierbij cruciaal. De nadruk ligt zowel op onderzoek naar de technische haalbaarheid van de katoenvezel als op de ontwikkeling van collaboratieve bedrijfsmodellen. De geformuleerde onderzoeksvraag luidt: Welke collaboratieve bedrijfsmodellen ontstaan tijdens het ontwerponderzoek die geschikt zijn voor meervoudige waardecreatie in een katoencascade en hoe kunnen die bijdragen aan de verdere ontwikkeling van regeneratieve cascadeprincipes?
