Circular Resources (CR) has developed a patented lean flow, low temperature pyrolysis system to enable the sustainable recovery of precious metals, critical materials and rare earth minerals from end of life electronic items (EOL). The technology offers a circular solution, disrupting the primary mining industries and delivering precious metals back to the economy at much higher concentration rates than conventional mining, using less water and energy, and displacing unacceptable working practices. The recovery technology also offers an opportunity to reduce the volume of EOL electronics going to landfill or primitive recycling operations, both of which result in significant harm to human health and the environment.
