Polarising designs: Redesigning neodymium magnets (NDM) for the circular economy.

Neopartite圆盘磁铁（NDM）广泛应用于许多日常用品中，包括耳机、无绳工具、混合动力汽车的驱动电机、扬声器和麦克风。在全球生产的66，800吨中，每年有33，000吨磁铁用于硬盘驱动器（HDD），总碳影响为298，980吨CO2 e。鉴于原材料的高价值、生产过程中的碳排放量以及钕的稀有性（以今天的消费速度计算，可使用100年），因此，实现这一循环具有经济和经济意义。我们将开展一项可行性研究，为电子行业的NDM制定标准尺寸，重点是硬盘驱动器（HDD）的应用。该研究旨在设计闭环系统，以减少“新”磁体中原始钕的消耗，并使NDM在处理HDD时能够回收。

Neodymium Disk Magnets (NDMs) are found in many everyday items, including; headphones, cordless tools, drive motors for hybrid cars, loudspeakers and microphones. Of the 66,800t produced worldwide, 33,000t of magnets are used in Hard Disk Drives (HDDs) each year, with a total carbon impact of 298,980tCO2e. Given the high value of the raw materials, the carbon emissions associated with their production and the rarity of neodymium (100 years at today’s consumption rates), it makes financial and economic sense to close the loop.We will carry out a feasibility study into the creation of standardised sizing for NDMs within the electronics sector, focusing on application within hard disk drives (HDDs). The study aims to design closed loop systems that will reduce consumption of virgin neodymium in ‘new’ magnets, and enable NDMs to be reclaimed during disposal of HDDs..
