For the transition to a more circular economy,it is important to know how the cycling of resources will affect value creation of businesses (Ellen MacArthur Foundation, 2013). Key business model strategies that are identified by Bocken et al. (2016) that fit the approach of slowing and closing resource cycles are ‘Extending product value’and‘Extending resource value’. In these strategies,the residual value of products or resources is exploited by turning otherwise wasted product (parts) or materials into new forms of value.
Construction and demolition waste (CDW) is the most important waste stream in the EU in terms of mass, with around 340 million tonnes between 2010 and 2018 (EEA, 2020). Most member states achieved a recovery target of 70% for this fraction, however, it is mainly based on backfilling or downcycling. Materials coming from demolition and renovation work are not often available for reuse or recycling activities, with some noticeable exceptions in the case of some pioneering Urban Resource Centres (URCs). URCs are physical centres that promote the circular economy at local level (Partnership on Circular Economy, 2019) prioritizing reuse, preparation for reuse, upcycling and remanufacturing activities over material recycling. This is an emerging concept throughout Europe, that has received much policy attention given its potential to help achieve Circular Economy goals set by the European Commission. So far there have been no systematic analyses of URCs, their operation and their impact. The goal of our paper is twofold: 1) to understand how frontrunning URCs currently operate and 2) to derive conclusions/policy recommendations/design principles for URCs. This article presents a comparison of seven URCs that to some extent allow the reuse of CDW in their locations. The data has been gathered in guided study visits to the different locations, complemented by additional information provided by the managers of the URCs through their yearly reports and follow up conversations. The research took place as part of the project Centers for Urban Resources, Reuse and Remanufacture (Cure+), which aims to establish URC pilots in the four project cities (Riga, Tartu, Kavala and Barcelona).
Learning objects are bits of learning content. They may be reused 'as is' (simple reuse) or first be adapted to a learner's particular needs (flexible reuse). Reuse matters because it lowers the development costs of learning objects, flexible reuse matters because it allows one to address learners' needs in an affordable way. Flexible reuse is particularly important in the knowledge economy, where learners not only have very spefic demands but often also need to pay for their own further education. The technical problems to simple and flexible are rapidly being resolved in various learning technology standardisation bodies. This may suggest that a learning object economy, in which learning objects are freely exchanged, updated and adapted, is about to emerge. Such a belief, however, ignores the significant psychological, social and organizational barriers to reuse that still abound. An inventory of these problems is made and possible ways to overcome them are discussed.
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.
In het kader van het Hoogwaterbeschermingsprogramma (HWBP) neemt de vraag naar klei voor het versterken van dijken toe, echter is het aanbod beperkt. Dit voorstel richt zich op ontwikkelen van nieuwe duurzame en kosteneffectieve technieken die het mogelijk maken om zout sediment uit estuaria in te kunnen zetten voor de dijkversterkingsopgave. Gebiedseigen materiaal, met name het zoute slib, kan worden ingezet voor klei productie in lokale dijkverzwaring en draagt bij aan duurzaam grondstoffenverbruik, klimaatadaptatie en de ecologische kwaliteit van estuaria. Met het project “Ontzouten rijpend slib voor Deltabescherming” gaan het lectoraat Sustainable River Management van de HAN, Ecoshape, Netics in samenwerking met partijen verenigd in het interbestuurlijk project IBP-VLOED onderzoeken hoe zout slib (kosten)effectief kan worden ontdaan van het zout, zodat het gebruikt kan worden in de regionale dijkversterkingsopgave. In IBP-Vloed zijn alle relevante nationale en regionale (semi)overheden, kennisinstellingen en belangenorganisaties vertegenwoordigd die zich richten op hergebruik van slib uit het Eems-Dollard estuarium. Beoogd wordt om een geschikte kosteneffectieve en schaalbare ontzoutingsmethode (strategie) te ontwikkelen die rekening houdt met de samenhang van de governing parameters en de heterogeniteit in samenstelling en structuur van het zoute slib uit estuaria zoals het Eems-Dollard gebied. De resultaten worden gepresenteerd tijdens een workshop en gebundeld in de vorm van best practices.
This proposal is a resubmission of an earlier proposal (Dossier nr: GOCH.KIEM.KGC02.079) which was not approved because of the too ambitious planning. As advised by the commission, the focus is kept only on the recycling of the mattress cover. The Netherlands has 180,000+ waterproof mattresses in the healthcare sector, of which yearly 40,000+ mattresses are discarded. Owing to the rapidly aging population it is expected to increase the demand for these waterproof mattresses in the consumer sector as well. Considering the complex nature of functional mattresses, these valuable resources are partly incinerated. To achieve a circular economy, Dutch Government aims for a 50% reduction in the use of primary raw materials in five key economic sectors including ‘consumer products’ by 2030. Within the scope of this research, Saxion together with partners (CFC BV, Deron BV, MRE BV & Klieverik Heli BV) will bring emphasis on Recycling (sustainable chemistry) of mattress covers. Other aspects such as reuse and re-designing are beyond the scope of this project proposal, for which a bigger consortium will be built during the course of this project. A case under study is a water-impermeable mattress cover made of 100% polyester with polyurethane (PU) coatings. The goal is to enable the circular use of textiles with (multilayer) ‘coatings’, which are not recyclable yet. These ‘coatings’ comprise functional coatings as well as adhesion layers. Therefore, novel triggerable molecular systems and the corresponding recycling processes will be developed. The coatings will be activated by a specific trigger (bio)-chemical solvation, heat, pressure, humidity, microwave, or combination of thereof. The emphasis is to develop a scalable coating removal process. Learnings will be used to build larger (inter)-national consortia to develop multiple industry closed-loop solutions required for 100% mattress circularity with desired functionality. The generated knowledge will be used for education at Saxion.
