真空吸塑成型PET托盘生命周期对环境影响分析
Analysis of environmental impact to life cycle of vacuum blister PET tray
摘要
Abstract
Aiming to systematically evaluate the environmental impact of vacuum blister molding for the manufacturing of PET blister trays,a 1-t polyethylene terephterate(PET)blister tray was selected as a functional unit.Based on an as-sessment method for the whole life cycle(LCA)and the environmental impact index of climate change(GWP)as a re-search focus,a carbon emission calculation model was established for the vacuum blister PET tray on the eFootprint sys-tem.The material consumption,energy consumption,and environmental impact evaluation indexes of the production process were quantitatively analyzed by the LCA calculation.The results indicated that in the entire production process of PET blister trays,the treatment of non-methane total hydrocarbon and PET sheet extrusion were the key issues with a higher cumulative contribution to carbon emissions,accounting for 47.67%and 30.22%respectively.Electricity is the key AP with a higher cumulative contribution to carbon emissions,accounting for 22.80%.Through capturing the car-bon footprint of the whole life cycle of the vacuum blister PET tray,the direction of future emission reduction of this pro-duction process was given.According to the concept of energy saving and emission reduction,the two key contributing factors in the process of vacuum blister molding were improved.关键词
