Silex World bets on urban mining for critical materials

Silex World Ltd is expanding its focus on urban mining to recover rare earths and other strategic materials from electronics, magnets, scrap and industrial waste. The Leeds spinout says the approach could help build more resilient supply chains for advanced manufacturing as demand rises.

Why it matters: - Silex World is targeting a growing source of critical materials already embedded in products, factories and waste streams. - The approach could ease dependence on newly mined supply and support more resilient regional supply chains for advanced manufacturing. - The company sees urban mining as a way to recover rare earth elements and other strategic materials for uses in electrification, renewable energy, defence, electronics and robotics.

What happened: - Silex World Ltd, a University of Leeds spinout focused on critical materials processing, announced an increased focus on urban mining on September 2, 2026. - The company said the strategy is part of its plan to develop diversified sources of rare earth elements and other strategic materials. - Silex World is developing technology in the United Kingdom and is also progressing international deployment, including activity in India.

The details: - Silex World wants to recover materials from end-of-life permanent magnets, electronic and electrical equipment, manufacturing scrap, rare earth-bearing industrial residues, strategic metal-containing secondary materials, and selected mineral and industrial feedstocks. - The company says its technology platform is designed to process multiple feedstocks rather than depend on a single mine, waste stream or supply route. - Its integrated approach combines material recovery technologies with continuous low-energy processing, modular infrastructure, multi-feedstock capability and digital traceability. - The goal is to move materials from waste and secondary resources back into verified industrial supply chains. - Silex World says urban mining can also reduce transportation needs by processing materials closer to where they arise in cities, manufacturing centres and industrial regions. - The company does not expect recycled materials alone to meet future demand and sees primary resources, industrial residues and recycled materials becoming interconnected in diversified supply chains.

Between the lines: - The pitch is not traditional recycling alone. Silex World is aiming at the harder problem of separating and upgrading complex secondary materials into usable industrial inputs. - That matters because many of the most valuable materials are dispersed across mixed waste streams, making recovery technically and economically challenging. - India stands out as an early target because its manufacturing base, electronics sector and expanding automotive and renewable-energy industries could supply large secondary material streams while also creating demand for recovered materials. - The company is framing urban mining as part of a broader shift toward a circular critical materials economy rather than a standalone waste solution.

What's next: - Silex World plans to continue developing scalable recovery and processing technologies for regional deployment. - The company aims to build processing infrastructure that can accept materials from multiple sources and return recovered strategic materials to productive use. - Similar deployment opportunities exist across the United Kingdom, Europe, North America and other industrial economies. - Silex World said its longer-term objective is to connect recycling, mining and manufacturing into one supply system for critical materials.

The bottom line: - Silex World is betting that the next wave of critical materials supply will come as much from discarded products and industrial waste as from the ground.
