Kozma, András (author), Odenbreit, Christoph (author), Braun, Matthias (author), Veljkovic, M. (author), Nijgh, M.P. (author)Circular Economy refers to a move from linear business models, in which products are manufactured from raw materials, used and then discarded, to circular business models where products or parts are re-used, remanufactured or recycled. Structural steel is highly compatible with this concept; however, when steel-concrete composite structures are...journal article 2019

Bocken, N.M.P. (author), Strupeit, Lars (author), Whalen, Katherine (author), Nußholz, Julia (author)The circular economy has been heralded as a potential driver for sustainable development by business, academia, and policymakers. In a future circular economy, new business models are needed that slow, close and narrow resource loops to address key resource and climate challenges. After a phase of excitement and inspiration, an...review 2019

Schraven, D.F.J. (author), Bukvić, Uroš (author), Di Maio, F. (author), Hertogh, M.J.C.M. (author)Recent literature has recognized the difficulty of implementing Circular Economy (CE) in supply chains. This has not yet led to a clear understanding of the reasons. This is critical to address, because the difficulty stalls the CE transition and suspends its benefits. Therefore, this paper investigates the reasons for the difficulty of...journal article 2019

Amenta, L. (author), Attademo, Anna (author), Remøy, H.T. (author), Berruti, Gilda (author), Cerreta, Maria (author), Formato, Enrico (author), Palestino, Maria Federica (author), Russo, Michelangelo (author)Resource consumption and related waste production are still rapidly increasing all over the world, leading to social and environmental challenges and to the production of the so-called ‘wastescapes’. Peri-urban areas—in-between urban and rural territories—are particularly vulnerable and prone to develop into wastescapes because they are...journal article 2019

Türkeli, Serdar (author), Schophuizen, M.J.F. (author)In this article, we highlight the pressing need for integrating the windows of opportunities that digital transformation of education opens up with circular economy education to accelerate the achievements of sustainability outcomes. Circular economy transition, as a multi-scalar process, relates to several contexts, e.g., product, firm,...journal article 2019

Van den Berghe, K.B.J. (author), Vos, Martijn (author)The hypothesis of this paper is that the circular economy (CE) has the potential to (re)balance the conflict within urban spatial planning between ‘place as a location’ and the ‘organization of space’. The former dominates the latter following a shift from a Fordist towards a finance and real-estate driven regime. A consequence is that existing...journal article 2019

(author), Gutsche, Jens-Martin (author)Improving waste and resource management entails working on interrelations between different material flows, territories and groups of actors. This calls for new decision support tools for translating the complex information on flows into accessible knowledge usable by stakeholders in the spatial planning process. This article describes an open...journal article 2019

Wandl, Alex (author), Balz, Verena Elisabeth (author), Qu, L. (author), Furlan, C. (author), Arciniegas Lopez, G.A. (author), Hackauf, U.D. (author)The concept of circular economy (CE) is high on the agenda of many planning agencies in European countries. It has also become a prominent issue in European academic education institutions. It is expected that spatial planning and design can support and add the spatial quality dimension of such a transition towards CE. However, incorporating the...journal article 2019

Ingemarsdotter, E.K. (author), Jamsin, E. (author), Kortuem, G.W. (author), Balkenende, R. (author)This paper focuses on how the Internet of Things (IoT) could contribute to the transition to a circular economy (CE), through supporting circular business model and design strategies. While literature has highlighted the opportunities for IoT to support circular strategies in business, little has been published about actual implementations in...journal article 2019

Ploeger, H.D. (author), Prins, M. (author), Straub, A. (author), Van den Brink, Robert (author)Purpose: A paradigm in circular economy (CE) is that suppliers retain ownership of their products and materials, and that the users “only” pay for services. In many legal systems, however, elements incorporated in a building are considered to be fixtures, and therefore legally part of the building. This means that ensuring multi-cyclic...journal article 2019

Brown, P.D. (author), Bocken, N.M.P. (author), Balkenende, R. (author)We investigate why companies collaborate within the circular oriented innovation process. The purpose is to understand what motives trigger collaborative circular oriented innovation, as well as conditions, drivers and barriers. First, we define circular oriented innovation building on sustainable oriented innovation literature. Subsequently,...journal article 2019

(author)Access-based product-service systems (AB-PSS) have the potential to lower environmental impacts. Currently, a lack of consumer acceptance and, consequently, low adoption levels of AB-PSS are challenges preventing the realisation of their sustainability potential. This study proposes temporary product customisation to lower barriers for the...journal article 2019

Amosov, M. V. (author), Zlatanovic, L. (author), Lam, K.L. (author), Solomonides, S. (author), van der Hoek, J.P. (author)The wastewater chain of Amsterdam offers an opportunity to recover up to 100% of phosphorus per year, versus 47% currently recovered. However, for the stakeholders of Amsterdam (e.g. citizens, business) it remains difficult to scale-up existing solutions for resource recovery. Mainly, due to the limitations of the widelyused methods (e.g. mass...conference paper 2019

Sheldon, R.A.
