Abstract

The Haloclean process, a rotary kiln process for pyrolysis, developed by researchers at the Forschungszentrum Karlsruhe, Germany makes it possible to recover copper and precious metals from the scrap, ready for recycling. Pyrolysis neatly turns brominated electronic scrap plastics into recyclable copper and methanol feedstock while removing the halogens. The process has demonstrated its ability to recycle brominated electronic scrap in extensive parametric studies. A method suitable for the selective production of HBr in the presence of chlorine is the treatment of the pyrolysis oils with molten polypropylene. This treatment is offers the possibility to use the gas and liquid fraction from pyrolysis of electronic scrap as fossil fuel substitute in copper smelter processes or as feedstock for methanol production via gasification.
