A LCI Study on a Closed Loop Post Consumer PET Bottle Recycling Process

摘要

A LCI study was done on a feedstock recycling process of post consumer (PC) PET bottles called AIES Process. AIES process established a closed loop recycling of PET resin for food contact use by obtaining high purity BHET (bis-2(hydroxyethyl) terephthalate), the monomer, without dissolving itself down to raw materials of PET such as terephthalic acid, dimethyl terephthalate and ethylene glycol. Actual engineering data of AIES process commercial plant of AIES process are employed for the study. The study proved energy consumption for out-putting recycled resin requires only a half of the energy that virgin resin production requires if FSE(feed stock energy) is counted into.
