TYRE RECYCLING PROCESS
Composite Recycling Ltd has developed the first commercially viable process for recycling whole tyres. The process uses molten zinc at 450 °C to recover pyrolysis oil and carbon black and steel in a sink-float separation. Our tyre recycling process significantly reduces the capital and operating costs of an industrial scale plant compared to the traditionally used rotary kiln processes, which are uneconomical as the tyres need to be shredded prior to processing. Moreover it takes less than 30 minutes to degrade a whole tyre. Our process uses whole tyres and is, as a result, economic.
PCB RECYCLING PLANT
Every year about 400,000 tons of printed circuit boards (PCBs) are generated in Europe, a large resource of precious and other metals. PCBs are used to mechanically support and electrically connect electronic components. They are used in almost all electronic equipment such as televisions, computers or mobile phones. Because of the low precious metal content of low or medium value PCBs it is generally uneconomical to recycle such PCBs. Our PCB pyrolysis process is a metal concentrating process. Metals present in the PCBs such as gold, copper, tin or zinc are concentrated within the separation chamber.
Composite Recycling was awarded Phase 1 H2020 funding for its application entitled “PCBRec process: Waste Printed Circuit Board (WPCB) Recycling with Molten Salts”
