The University of Birmingham, UK, has announced the successful completion of a project demonstrating that the rare earth magnets in loudspeakers can be successfully recycled. REAP used a patented recycling technology called hydrogen recycling of magnet scrap HPMS that was developed within the university to extract and de-magnetise the neodymium iron boron NdFeB alloy powders embedded in loudspeakers from end-of-life cars and flat screen TVs.

The alloy powders were then purified, and re-compacted to produce new magnets that had magnetic properties comparable to the initial starting magnet. The project also confirmed the quantity and economics of recycling loudspeaker magnets, and provides a strong platform to scale up production. European Metal Recycling performed a comprehensive assessment of scrap, encompassing extraction, characterisation of components, degree of pre-processing and potential for automation.

HyProMag and the University provided analysis of the extracted magnets focusing on determining the recyclability and market potential, both as a viable feedstock of NdFeB and as a potential route-to-market.

The World Steel Association worldsteel has published steel industry's sustainability performance via its sustainability indicators. A discussion paper by the UN Environment Programme and International Resource Panel sets out that global exports of material resources per capita doubled between and —while overall global extraction of materials tripled in the same period—but fewer exporters are meeting this demand.

A ground-breaking project to recycle the rare-earth magnets found in loudspeakers has been completed by EMR and its partners HyProMag and the University of Birmingham. The innovative project entitled Rare-Earth Extraction from Audio Products REAP has highlighted how advanced processes and technology can be used to create new sustainable and low carbon impact feedstock for the UK supply chain, recycling material which would otherwise be lost to landfill. EMR has a long track record of re-investing its profits back into research and development projects, as well as new technology. Although the research focused on the powerful rare-earth magnets found in audio devices, the findings will assist in improving recycling processes for many other products including electronic sensors and electric window motors found in current end-of-life vehicles and in future in the drive motors of electric vehicles. The UK has no domestic source of the critical element neodymium, which are used to make rare earth magnets found in wind turbines, mobile phones and many other electronic products. HyProMag and University of Birmingham, meanwhile, provided analysis of the extracted magnets, with a particular focus on determining the overall recyclability and market potential of these materials. Following the success of speaker magnet liberation within the project, HyProMag have assessed that focus should also be placed on the rare-earth magnets in hybrid and electric vehicles where quantities of rare-earth magnets are becoming substantially higher.

Rare opportunity to recycle rare earths

Is it possible to cut ferrite magnets without losing magnetism? The use of magnets is very wide, with many and varied applications, however, questions arise such as that at the beginning of this article, either for an important reason, or just curiosity. Cutting, drilling or welding activities can give rise to the wish to cut ferrite magnets. While this is possible under ideal circumstances, it is extremely difficult to perform correctly. If one is not careful, a powerful magnet will rapidly implode, or lose its magnetic field.

Salvaging Magnets From Speakers.


Magnetic materials specifically permanent magnets are critical for the efficient performance of many renewable energy technologies. The increased reliance on renewable energy sources has accelerated research in energy-related technologies the world over. The use of rare-earth RE metals in permanent magnets continues to be a source of greater concern owing to the limited RE supply coupled with dwindling reserves on the globe. This review focuses on how this has impacted on the state-of-the-art magnetic materials that continue to play a pivotal role in driving renewable energy technologies. Magnetic materials are perceived as key in driving the 21st century industrial revolution, and the participation of South Africa in this energy paradigm is critical in driving a new industrial revolution within the African continent. A number of opportunities are highlighted, and clarity is given on the several ubiquitous misconceptions and the risks on the heavy reliance on a single source for RE magnetic materials.

Recycling at Officeworks – Don’t Bin It, Bring It

Have you ever listened to music before? Maybe you got curious as a kid or as a scrapper and took apart an old stereo or a speaker to see what was inside. Most of the time you will just see plastic, wood, and then you will find something interesting…a magnet. Many people wonder if these magnets are worth a lot of money based off of previous articles and videos that the iScrap App team has done on magnets…but we hate to be the bearer of bad news today. Speaker magnets are ceramic magnets and have no metal in them. You will be able to use these magnets to test ferrous vs. Sometimes you can never have enough magnets around, especially when you are on the road and some fall off of your truck or even stay stuck to the scrap steel that you have found. Magnetic Broom for Picking Up Nails.

Neodymium is an REE that has been used in neodymium iron boron (NdFeB) permanent magnets since the s, between 8% and 35% of which are applied in hard disk.

You probably have an old set of speakers lying in some corner of the house. Dust them off; it's time to breathe new life into those trusty woofers. It doesn't matter whether they still work or not, there's a perfect weekend DIY project waiting for you.

For the speakers they received, Yandex partnered with a local recycling company in Russia that will disassemble the devices and recycle their components. Through this process, speakers that were mainly collecting dust in storage will go on to serve new uses. Their plastic will be used in the construction of windows, while the metal from the speakers will be sent to scrap metal recyclers. What cannot be reused or recovered from the speakers will be disposed of responsibly.

The best way to use a speaker system is to recycle them for various purposes or donate them.

While the recycling of rare earth magnets — including neodymium and samarium cobalt — is technically possible, it is not scalable or efficient for most businesses. In fact, less than 1 percent of rare earths were recycled as of , due to a combination of technical, financial, and political reasons. Not to mention, it would reduce if not eliminate the need for overseas mining.
