(author), Gutfleisch, O (author), Buchert, M (author), Steenari, B-M, (author), Van Gerven, T (author), Jones, P.T. (author), Binnemans, K (author)NdFeB permanent magnets have different life cycles, depending on the applications: from as short as 2–3 years in consumer electronics to 20–30 years in wind turbines. The size of the magnets ranges from less than 1 g in small consumer electronics to about 1 kg in electric vehicles (EVs) and hybrid and electric vehicles (HEVs), and can be as...review 2017

Taebi, B. (author), Kloosterman, J.L. (author)AbstractThis paper approaches the choice between the open and closed nuclear fuel cycles as a matter of intergenerational justice, by revealing the value conflicts in the production of nuclear energy. The closed fuel cycle improve sustainability in terms of the supply certainty of uranium and involves less long-term radiological risks and...journal article 2007

Megevand, B.P.N. (author), Cao, Wen-Jun (author), Di Maio, F. (author), Rem, P.C. (author)This paper aims to summarize, propose, and discuss existing or emerging strategies to shift towards a circular economy of materials. To clarify the landscape of existing circular practices, a new spectrum is proposed, from product-based strategies, where entire products go through several life cycles without being reprocessed, to material-based...journal article 2022

Di Maio, F. (author), Rem, P.C. (author)In order to move towards a more sustainable development, it is necessary not only to minimize the use of materials in the design stage and to find new materials as alternatives to nonrenewable ones (e.g. optical fiber instead of copper, biopolymers instead of polymers from oil) but also to reclaim as much as possible material value through...journal article 2015

van Straten, Bart (author), Dankelman, J. (author), van der Eijk, A. (author), Horeman, T. (author)The Circular Economy faces a growing interest. The aim of this study is to determine the feasibility of a circular approach towards reusing discarded hospital instruments and stainless steel waste. Secondary, this study aims to identify if any cost savings can be realized by following a circular instrument repair and recycling approach....journal article 2021

Arnold, Mona (author), Pohjalainen, Elina (author), Steger, Sören (author), Kaerger, Wolfgang (author), Welink, J.H. (author)Electronics containing growing quantities of high value and critical metals are increasingly used in automobiles. The conventional treatment practice for end-of-life vehicles (ELV) is shredding after de-pollution and partial separation of spare parts. Despite opportunities for resource recovery, the selective separation of components...journal article 2021

Hartwell, R.C. (author), Macmillan, Sebastian (author), Overend, M. (author)Reuse and high-value recycling have a pivotal role to play in reducing waste and minimising carbon emissions in the built environment. Design strategies for such recovery methods have yet to be fully established in the façade industry. Meanwhile, stringent regulations, aimed at reducing operational carbon emissions of buildings and improving...journal article 2021

Hartwell, Rebecca (author), Coult, Graham (author), Overend, M. (author)Glass is one of the UK’s eight energy-intensive industries. As such, it is under scrutiny to decouple growth in production from greenhouse gas (GHG) emissions. Recycled glass, also known as cullet, requires less energy to melt than primary raw materials in new glass production. The use of cullet thus reduces the energy intensity per unit of...journal article 2022

Polyportis, Athanasios (author), Mugge, R. (author), Magnier, L.B.M. (author)Despite their environmental benefits, products made from recycled materials are not readily adopted. Prior studies focused on improving consumer adoption via product attributes and marketing elements, but the impact of product appearance remains a gap in the literature. This research contributes by investigating how observability of the recycled...journal article 2024

Ogundiran, MB (author), Nugteren, H.W. (author), Witkamp, G.J. (author)Combined management of coal combustion fly ash and waste aluminium anodising etching solutions using geopolymerisation presents economic and environmental benefits. The possibility of using waste aluminium anodising etching solution (AES) as activator to produce fly ash geopolymers in place of the commonly used silicate solutions was explored...journal article 2016

Davis, Chris B. (author), Aid, Graham (author), Zhu, B. (author)Research on value pathways for organic wastes has been steadily increasing in recent decades. There have been few considerably broad overview studies of such materials and their valuation potential in the bio-based economy in part because of the vast multitude of materials and processes that can be used to produce energy carriers, chemicals,...journal article 2017
