The recycling of halogenated waste plastics poses serious problems. The pyrolysis of PP/PE/PS/PVC was performed by using CaCO3 sorbent to remove the chlorine content during the process. The presence of water (10 wt%) in the plastic mixture did not effect the characteristics of liquid products or the dechlorination efficiency of CaCO3 sorbent. The halogen free liquid products can be used as a feedstock in refinery or fuel oil.
