PET bottles were composed of several different materials such as PET, HDPE, PVC and PP, it is necessary for recycling of PET bottles to precede seperation of each material. This study is purposed of recycling of PET bottles by separation using float and sink method. Pure PET is obtained a proportion of 94% on condition that bottle labels were removed by using tap water. In case the labels were attached on the bottles, PET was unable to obtain because of PVC and PET sink, and PP and HDPE float. Therefore, the labels should be removed before separation of PVC lebels substituted for PP or PE material. The various physical properties of recovered PET and HDPE were measured and compared with the original PET and HDPE, and it is identified that recycling is possible as a result.

In this study, life cycle assessment(LCA) technique was employed to evaluate the environmental impact of material recycling of polyethylene terephthalate(PET) bottle. Life cycle inventory was established based on the data collected from recycling companies in Korea. Simapro 5.0 LCA software and Eco-indicator 95 index were used for the analysis. The biggest impact by the material recycling of PET bottle on the environmental category was the global warming. It is because melting and production of the recycled PET product consume a significant amount of electricity and energy. In the environmental pollution discharge, $CO_2$ emission was the highest, followed by NOx. This is probably due to the use of diesel and gasoline in the consumption of electricity and transportation. All the environmental impact showed (-) value except the ozone layer depletion, which means that the material recycling of PET bottle is environmentally fair. The use of recycled PET product greatly reduced the environmental impact.
