Recently, the shortage of landfill site has become a serious environmental problem according to an increase in the amount of waste disposal. A variety of recycling processes about the waste plastics with large capacity have been proposed from the environmental viewpoints. Especially the liquefaction process using the Ga-Si catalyst is able to recover the BTX (benzene, toluene and xylene) from the waste plastics selectively and efficiently. In this study, the inventory of BTX recovery system for the industrial waste plastics was analyzed, and the environmental loads such as energy consumption, air emission and solid waste were compared with the BTX production system from crude oil adding the waste systems of industrial waste plastics. As a result, it was confirmed that the BTX recovery system was able to reduce 40% energy consumption more than the BTX production system adding the waste systems of plastics. It was suggested that this system was effective as the BTX production system, besides the recycling system for the industrial waste plastics.
