van Staveren, D. (author), Cuppen, Eefje (author), Heurkens, E.W.T.M. (author), Vos, Marije (author)Construction sectors have a long way to go to realize a circular economy. Many organizational barriers and institutional characteristics inhibit the sector’s transition to circular practices. Nevertheless, within this early phase of the transition, several building projects were realized. This research aims to learn from these frontrunners, in...conference paper 2022

Jansen, B. (author), van Stijn, A. (author), Gruis, V.H. (author), van Bortel, G.A. (author)The built environment can be made more circular by gradually replacing building components with more circular components during construction, renovation, or maintenance. However, many different design options can be seen as circular. Although there is a growing number of studies about circular design options, research on what makes these options...journal article 2022

Joustra, J.J. (author), Bakker, C.A. (author), Bessai, R. (author), Balkenende, R. (author)The design of composite products for a circular economy is challenging. Materials such as glass-fibre-reinforced plastics have long product lifetimes but are hard to recycle. For the effective reuse and recycling of products, parts, and materials, recovery strategies must be selected and implemented in the product design stage. This extends the...journal article 2022

Lundgren, Rebecka (author), Kyrö, Riikka (author), Jylhä, T.E. (author)The pressing need to implement a more circular economy has led to advancements in the research field. In the spatial context, sharing spaces and access-over-ownership models have the potential to mitigate the detrimental environmental impacts of space use. This study aims to adapt an existing theoretical framework on access-based consumption...journal article 2022

Tsui, T.P.Y. (author), Derumigny, Alexis (author), Peck, David (author), van Timmeren, A. (author), Wandl, Alex (author)In recent years, implementing a circular economy in cities has been considered by policy makers as a potential solution for achieving sustainability. Existing literature on circular cities is mainly focused on two perspectives: urban governance and urban metabolism. Both these perspectives, to some extent, miss an understanding of space. A...journal article 2022

Reprocessing Zamak laryngoscope blades into new instrument parts: an ‘all-in-one’ experimental studyvan Straten, Bart (author), Tantuo, B.N. (author), Sperna Weiland, Nicolaas H. (author), Dankelman, J. (author), Hendriks, B.H.W. (author), Horeman, T. (author)Introduction: Disposable instruments in healthcare have led to a significant increase of medical waste. The aim of this study is to validate the recycling of disposable Zamak laryngoscope blades into new medical products by using a new ‘all-in-one’ affordable reprocessing setup as alternative for die-casting. <br/>Methods: An “all-in-one”...journal article 2022

Bucci Ancapi, F.E. (author), Van den Berghe, K.B.J. (author), van Bueren, Ellen (author)The built environment plays a central role in the transition towards the circular economy as they concentrate major consumer and polluter human activities. However, the way BEs are – and need to be – driven by policy to reach cities’ circular goals is still an under-researched aspect. Particularly, there is limited knowledge of policy...review 2022

Sheldon, R.A. (author), Brady, Dean (author)In the movement to decarbonize our economy and move away from fossil fuels we will need to harness the waste products of our activities, such as waste lignocellulose, methane, and carbon dioxide. Our wastes need to be integrated into a circular economy where used products are recycled into a manufacturing carbon cycle. Key to this will be the...review 2022

Van den Berghe, K.B.J. (author)Bij de herontwikkeling van bedrijventerreinen in steden legt de bestaande industrie vaak het af tegen woningbouw. Maar TU Delft-onderzoeker Karel Van den Berghe laat via een rekenoefening zien dat dit ook ten koste gaat van de circulaire ambities van steden. Want hoe kan Den Haag ooit verantwoord bouwen als de stad haar enige betonfabriek...report 2021

Sumter, Deborah (author)The circular economy offers an alternative to the linear economy (also called the take-make-use-waste society) we live in. It puts emphasis on using resources effectively by slowing and closing resources loops. Design is seen as enabler in a circular economy. Design decisions taken now have an impact on the recovery of products in the future....doctoral thesis 2021

Data availability about the material contents of buildings is significant challenge for planning future re-use potentials. Compiling material intensity (MI) data is time and resource intensive. Often studies end up with only a handful of datapoints. In...journal article 2021

Flipsen, Bas (author), Bakker, C.A. (author), de Pauw, I.C. (author)Designing products for the Circular Economy requires closing and slowing of loops by means of repair, reman-ufacturing, refurbishment, parts reuse and/or recycling. Ease of product disassembly facilitates these processes to be more cost-effective, resulting in a better circular strategy fit.
