SCREAM - Secure Critical Rare Earth Magnets for the UK

NdFeB磁体在应对气候变化的斗争中发挥着关键作用，因为它们被用于清洁技术，如电动汽车的风力涡轮机、发电机和电机。随着我们过渡到一个电子驱动的社会，对这些材料的需求将几乎呈指数级增长。这些材料的供应在地理上集中在全球某些地区，与所有其他与能源有关的材料相比，欧盟已确定这些材料具有最大的供应风险。Scream的目的是通过回收使用寿命结束的废料(EoL)中的磁铁，为英国提供这些材料的供应。HyProMag、Mkango稀土英国公司、GKN混合动力公司、欧洲金属回收公司(EMR)、捷豹路虎(JLR)、Bowers and Wilkins和伯明翰大学(UOB)将在Scream项目中合作，以确保英国关键的永久磁体。Scream财团将展示将废材料重新引入稀土供应链的两条创新路径。首先是扩大伯明翰大学开发的一项工艺，即从汽车、机器人、分离器、扬声器废料流中提取磁性废料的氢气处理工艺。二是为稀土供应链生产混合稀土碳酸盐。HyProMag将扩大这一过程，以开发适用于一系列应用的不同等级的磁体。鲍尔斯和威尔金斯、GKN和捷豹路虎将评估磁铁对一系列产品的适用性，并计算生产这些材料的环境足迹。该项目的产出将是马达、扬声器和含有回收磁铁的固定磁铁应用。

NdFeB magnets play a critical role in the fight against climate change as they are used in clean technologies such as wind turbines generators and motors in electric vehicles. As we transition to an electrically driven society then the demand for these materials will increase almost exponentially. The supply of these materials is geographically concentrated in certain parts of the globe and these materials have been identified as being of greatest supply risk compared to all other energy related materials by the EU. The aim of SCREAM is to provide a UK based supply of these materials by recycling magnets from end of life scrap (EoL). HyProMag, Mkango Rare Earths UK, GKN Hybrid Power, European Metal Recycling (EMR), Jaguar Land Rover (JLR), Bowers and Wilkins and the University of Birmingham (UoB) will work together in the SCREAM project to secure critical permanent magnets for the UK. The SCREAM consortium will demonstrate two innovative paths to introduce scrap material back into the rare earth supply chain. The first is to scale up a process developed at the University of Birmingham, "Hydrogen Processing of Magnetic Scrap" from automotive, robotic, separator, loudspeaker scrap streams. The second is to produce a mixed rare earth carbonate for the rare earth supply chain. HyProMag will scale this process to develop magnets that are different grades for a range of applications. Bowers and Wilkins, GKN and JLR will assess the suitability of the magnets for a range of products, and calculate the environmental footprint for production of these materials. The output of the project will be motors, loudspeakers and holding magnet applications containing recycled magnets.
