Abstract

With the rapid growth of economy, the use of plastic is increased. However, due to inefficient management plan after use of plastics, great quantities of recovered plastic waste is not properly treated. In addition, because most of waste plastic is landfilled, we are faced with many problems in landfill site and occurrence of leachate. In order to solve this problem, the new recycling system has to be established and be built up information system connected with local government, waste collector, and recycling companies. In this study, it was assessed LCA of PET. According to the inventory analysis of water emission, it is shown that the concentration of wastewater is low due to simplification of process and product constituent. The impact assessment was not performed in detail because of elements limit for factors. The material load equivalent, which has impact on ozone layer depletion in global scale was only obtained. To reduce environmental impact by using of PET products and to lead the effective use of resources, PET must be recycled and reused because of the problem of dioxin when it is incinerated.
