Journal ArticleDOI
Life Cycle Inventory of the Production of Rare Earths and the Subsequent Production of NdFeB Rare Earth Permanent Magnets
Benjamin Sprecher,Yanping Xiao,Allan Walton,J.D. Speight,Rex Harris,René Kleijn,Geert Visser,Gert Jan Kramer +7 more
TL;DR: It is concluded that recycling of neodymium, especially via manual dismantling, is preferable to primary production, with some environmental indicators showing an order of magnitude improvement.
Journal ArticleDOI
Effect of Chinese policies on rare earth supply chain resilience
Nabeel A. Mancheri,Nabeel A. Mancheri,Benjamin Sprecher,Gwendolyn Bailey,Jianping Ge,Arnold Tukker +5 more
TL;DR: In this article, the authors analyze the supply chain dynamics by specifically targeting a number of Chinese rare earths elements (REE) policies that have disruptive tendencies, focusing on how price responds to various resilience influencing mechanisms such as diversity of supply, regulatory frameworks and stockpiling.
Journal ArticleDOI
Trade-offs between social and environmental Sustainable Development Goals
Laura Scherer,Paul Behrens,Arjan de Koning,Reinout Heijungs,Reinout Heijungs,Benjamin Sprecher,Arnold Tukker +6 more
TL;DR: In this article, the authors analyse the interaction between two social goals (related to SDG1 Poverty and SDG10 Inequality) and three environmental goals and find that pursuing social goals is associated with higher environmental impacts.
Journal ArticleDOI
Recycling potential of neodymium: the case of computer hard disk drives.
TL;DR: It is found that recycling of computer HDDs is currently the most feasible pathway toward large-scale recycling of neodymium, even though HDDs do not represent the largest application of ne Codymium.
Journal ArticleDOI
Metal supply constraints for a low-carbon economy?
Arjan de Koning,René Kleijn,Gjalt Huppes,Benjamin Sprecher,Guus van Engelen,Arnold Tukker,Arnold Tukker +6 more
TL;DR: In this article, the authors estimate the required extraction of Fe, Al, Cu, Ni, Cr, In, Nd, Dy, Li, Zn, and Pb until 2050 under several technology-specific low-carbon scenarios.
