Campbell-Johnston, K. (author), Roos Lindgreen, E. (author), Mondello, G. (author), Gulotta, T.M. (author), Vermeulen, W.J.V. (author), Salomone, R. (author)The strategic relevance of extracting raw materials from waste from electrical and electronic equipment (WEEE) in the EU is increasing due to value chain risks caused by geopolitical instability, accessibility of specific minerals, and decreasing reserves due to growing extraction rates. This article examines the quantities of so-called critical...article 2023

Nedeljkovic, M. (author), Mylonas, A. (author), Wiktor, V. (author), Schlangen, E. (author), Visser, J.H.M. (author)Fine recycled concrete aggregates (fRCA, 0–4 mm) are produced from demolished concrete structures and consist of natural aggregates and old cement mortar. The presence of old cement mortar has detrimental effect on the fresh properties and trength of new concrete. This study aims to investigate the working mechanism and effectiveness of...article 2022

(author), Godoi Bizarro, D.E. (author), Szklarz, S.P. (author), Barros, E. (author)Sustainable development is a complex, multi-disciplinary and multi-sectoral challenge with often contradicting objectives. As such, in the strongly fragmented construction sector often only single aspects of the challenge are subject of innovations. Therefore the construction sector faces a huge challenge to meet multiple goals set a.o. in the...conference paper 2022

Mehta, R. (author), Golkaram, M. (author)There is a major push by governments and value chain partners to move towards circular options for difficult-to-recycle post-consumer products such as waste mattresses.[1] In the Netherlands alone ~1.5 million mattresses are discarded yearly, of which majority (>60%) is incinerated.[2] A sustainable solution to recycle waste mattresses is...conference paper 2022

Li, C. (author), Mogollón, J.M. (author), Tukker, A. (author), Dong, J. (author), von Terzi, D. (author), Zhang, C. (author), Steubing, B. (author)Offshore wind energy (OWE) is a cornerstone of future clean energy development. Yet, research into global OWE material demand has generally been limited to few materials and/or low technological resolution. In this study, we assess the primary raw material demand and secondary material supply of global OWE. It includes a wide assortment of...article 2022

(author)To conserve resources and enhance the environmental performance, China has launched the “Zero waste” concept, focused on reutilization of solid waste and recovery of materials, including copper. Although several studies have assessed the copper demand and recycling, there is a lack of understanding on how different waste management options would...article 2022

(author)One of the key challenges for plastics in a circular economy is its degradation during use, washing and reprocessing. The reduced quality of recycled plastic waste leads to its use in inferior applications. This study presents a novel quality model which incorporates degradation, degree of mixing and contaminations. The model estimates a single...article 2022

Bex, G.J.P. (author), Ingenhut, B.L.J. (author), ten Cate, T. (author), Sezen, M. (author), Ozkoc, G. (author)The use of recycled polymers in 3D printing technologies has recently become a promising research topic because of the global concerns on plastic waste pollution and an increase in awareness of sustainability and circularity. In order to unlock the potentials of 3D printing beyond prototyping purposes, continuous fiber-embedded fused filament...article 2021
