Polyvinyl Chloride (PVC) of a thermoplastic resin is used in diverse applications including pipe, electric wire, and cable insulator due to its chemical stability and flame retardancy. With the rapid increase in the use of plastics, there is a growing interest in how to efficiently dispose of plastic waste. Current disposal methods include landfill, incineration, chemical recovery, etc. However, unlike other plastic products, PVC is difficult to recycle due to hydrogen chloride (HCl) generated from thermal decomposition, and it is released to the outside and is harmful to the environment and human body. Thus, removal of chlorine from PVC in the form of HCl at relatively low temperatures is important for the environment and for residue yields. In this study, PVC recycling was performed using organic solvents and layered double hydroxide (LDH). The use of organic solvents can facilitate PVC recycling at relatively low temperatures and atmospheric pressure. In addition, it can effectively remove HCl released due to the structure and anion of LDH. As a result, it shows that it is an efficient strategy in PVC recycling through low energy while reducing environmental pollution. |
