Organisation or Individual Expertise:
Composite Recycling Ltd developed a number of processes to recycle (pyrolyse) composite plastics such as printed circuit boards (PCB), automobile shredder residue (ASR), tyres and plastics. The recycling process for PCB and ASR uses molten salts as the direct heat transfer fluid and, simultaneously, uses this salt to separate the metals liquid or solid at the operating temperatures of 350-470°C. The metals sink in the molten salt and form a bottom metal phase. The pyrolysis reactor is a U-shaped structure and allows access to the molten salt so that materials i.e. solder or other accumulated metals (gold, indium, rare earths) may be removed intermittently. The resin of the PCBs pyrolysis whereas the reminder of the PCB i.e. copper and some stainless parts are also removed intermittently. This PCB recycling process combines pyrolysis with sink-float separation into one unit operation and concentrates the metals into one area reducing the cost of an industrial scale plant compared other processes. The tyre recycling process operated with molten zinc. The tyres decompose within 20 minutes into pyrolysis gases, carbon black and steel. The steel sinks and the carbon black is hovered off the zinc surface with the pyrolysis gases. In April 2015 we were awarded H2020, SME, Phase 1 for our tyre recycling process.
