生質塑膠環境效益評估暨延伸生產者回收責任推動專案工作計畫
| 中文摘要 | 本計畫目的在分析生質塑膠生命週期，並推動生質塑膠、發泡塑膠及行動通訊產品自主回收體系運作。為比較本土化傳統塑膠容器及生質塑膠容器環境效益，評估從原料生產階段至回收廢棄階段完整生命週期之環境衝擊，以1,000個產品為功能單位，結果顯示PLA產品較PSP托盤、EPS冷飲杯、PET及PVC蛋盒、HDPE購物袋低2—35%耗能；PLA產品較多數傳統塑膠低20—44%溫室氣體排放，但PLA產品則較傳統塑膠高39—59%微粒污染。此外，PS類產品則較其他塑膠材質高出81—93%人體毒性。另分析生質塑膠不同處理方式之成本效益，推估若部分PLA容器混入傳統回收體系中，將造成業者每公斤17元損失，故建議應建立生質塑膠識別系統，持續推動PLA分類回收，避免其混入傳統塑膠再利用處理體系。回收方式則以物質回收效益最高，每公斤可得8元之處理效益。 另本計畫檢討生質塑膠自主回收運作方式，雖初期生質塑膠回收量未能大幅提昇，但回收體系已建置，後續仍需持續監督輔導提昇回收成效。監督輔導發泡塑膠自主回收方面，99年回收率預估可達為50%。此外，本計畫亦協助廢行動通訊產品回收合作備忘錄之續簽，預計除原15家業者外，可增加8家通信業者加入，手機回收點將可提升至1萬點以上，可提升民眾回收便利性，建議後續可建立評估指標並調查業者舊廢手機回收比例及民眾棄置行為，以及分析執行機關回收量數據，增加資料可信度及流向透明度。 | ||

Environmental benefits assessment of biomass plastic and extended producer responsibility promotion
| 英文摘要 | The purpose of this project was to analyze life cycle of biomass plastic and to promote extended producer responsibility (EPR) recycling scheme of biomass plastic, expanded polystyrene (EPS) and mobile communication products. In order to compare local environmental benefits of biomass plastic containers with the traditional ones, we assessed the environmental impact from raw material production to disposal stage. The functional unit was chosen as 1,000 containers. The results showed Polylactide (PLA) products were 2-35% less energy consumption in comparison with polystyrene paper (PSP) trays, EPS cups, polyethylene terephthalate (PET) and polyvinyl chloride (PVC) egg boxes and high density polyethylene (HDPE) bags. PLA products emitted 20-44% less greenhouse gases than most traditional plastic products, but with 39-59% higher PM2.5 pollution. The human toxicity for PS products was 81-93% higher than others. Furthermore, we analyzed cost-effectiveness of biomass plastic on different end-of-life scenarios. The waste treatment business might lose NTD 17 per kilogram, if PLA containers were mixed into traditional recycling scheme. Therefore, we suggested that a recognition system for biomass plastic should be established. Recycling and sorting PLA should be promoted continually to prevent mixing with traditional plastic. For recycling methods, regenerating materials had the highest benefit. It could gain NTD 8 per kilogram from treatment. This project also reviewed EPR recycling method of biomass plastic. Although the recycling quantity of biomass was unable to increase significantly at the beginning, the recycling scheme has been established. It remained to be supervised and guided as a follow-up for increasing recycling effectiveness. For the EPR recycling scheme of EPS, the recycling rate in 2010 was estimated to reach 50%. Moreover, this project also aided in signing the Memorandum of Understanding for recycling mobile communication products. In addition to the original 15 mobile communication companies, other 8 companies were expected to join, the recycling spots for mobile phones would increase to more than 10,000. It could raise the convenience of recycling. We suggested establishing an evaluation index system for the recycling rate of mobile phones and public’s disposal behaviors. We also suggested analyzing the data of recycle quantity from implementing agencies, in order to increase the credibility of data and transparency of waste flow. | ||
