An autocatalytic converter reduces the toxicity of gases emitted by the exhaust pipes. They contain the Platinum Group Metals (PGMs) - platinum, palladium and rhodium. These are all valuable and useful for industrial processes, and on the European Union’s Critical Materials List.
Saguru dismantles used autocatalytic converters, crushes and leeches them before extracting the PGMs. Aluminium and cerium are also extracted during this process.
Other recycling methods do exist, but require high heat. Saguru’s method uses much lower temperatures, which makes the process more affordable and emits fewer toxic gasses. His process uses chemical reagents which are cheap, relatively common and environmentally friendly.
