Silex World Ltd is commercialising a suite of patented technologies for the extraction, concentration, and recycling of rare earth oxides, targeting one of the most strategically vital material groups in the global energy transition. Our focus is on the FeNdB family of permanent magnets, which are indispensable to high-efficiency power systems in wind turbines, electric vehicles, advanced computing, and consumer electronics. These magnets drive the performance of green technologies — yet the rare earths within them remain largely unrecovered at end-of-life due to the absence of a scalable, universal 'track-and-trace' system.
Silex is addressing this critical gap with a next-generation approach to Net Zero Materials Manufacturing, combining waste minimisation, critical materials recovery, and circular reuse. Our proprietary process enables efficient, environmentally sound recovery not only of rare earth elements such as neodymium and dysprosium, but also of titania, vanadium oxide, niobium, and tantalum from industrial waste streams. In addition, we are pioneering the safe handling and reapplication of residual uranium and thorium oxides for potential nuclear use cases. With a growing IP portfolio, strong academic partnerships, and high-impact applications across the green economy, Silex World Ltd offers investors early access to scalable, defensible innovations in the rare earths supply chain — aligned with national and global Net Zero targets.
Digitalised and Sustainable Approaches for Reusing, Repairing, Recycling Permanent Magnets from
Electronic Wastes (PermMag-DiSARE)
We are currently working on a UKINNOVATE funded project that is looking at ways to repair, recycle or reuse E-waste magnets.
The FeNdB group of permanent magnets are essential for green-energy transduction devices, which are widely used in consumer electronics, computers, automotives, and wind turbines. The size of magnets is determined by the energy required in transduction, which implies that the value of the magnet waste is then determined by the mass. Currently there is no universal system of 'track-and-trace' for any size of magnets.
Solution: A digital methodology for sifting FeNdB magnets based on reusability, repairability, and recycling (3R), which aligns with NetZero and becomes the sustainable approach for the magnet sector.
In PermMag-DiSARE, we are creating a knowledge exchange work plan with Indian collaborators, Karo-Sambhav and IIT-Roorkee, to transfer academic knowledge into industry and develop and grow a sustainable business model through technology exploitation, creating further pull for academia to develop new knowledge.
UoL (UK) and IIT-Roorkee (India) will drive academic parts of R&D on determining the course of 3R, whereas the industry partners Karo-Sambhav (India) with Silex & SGTech providing innovative solutions for 3R-centre, chemical/metallurgical processing, and magnet manufacturing and characterisations for device use, respectively.
R&D activities: Karo-Sambhav in India has established electronic waste recycling facilities in 70 cities, however, presently there are no means of separating different types of magnets for creating a digital 3R-centre.
