基于LCA理论的汽车零部件包装箱“以塑代木”对比研究

Comparative Study on Carbon Footprint of Ironwood Boxes and Polypropylene Recycled Packaging Boxes Throughout Their Life Cycle

目的旨在解决汽车零部件包装中一个长期存在的问题,即“以塑代木”还是“以木代塑”。通过评估聚丙烯可循环包装箱与铁木箱在整个生命周期中的碳排放量,探讨使用聚丙烯包装箱替代传统木箱的环保价值。方法研究采用生命周期评价(LCA)方法以铁木箱为例进行碳足迹研究,考虑从原材料获取、生产、使用到废弃处理等各个阶段的碳排放量。通过这种方法,可以更准确地评估包装箱在整个生命周期中的环保价值,并为未来的包装箱选择提供科学依据。结果研究发现,在整个生命周期中,聚丙烯可循环包装箱的碳排放量明显低于铁木箱。具体数据显示,铁木箱碳排放量约为571.265 kg,而聚丙烯包装箱约为铁木箱碳排放的四分之一。结论根据上述实验结果得出结论,聚丙烯可循环包装箱在减少碳排放方面具有显著效果,因此,在汽车零部件包装材料选择上,“以塑代木”是值得推广的。这一发现为包装行业提供了重要的参考,有助于推动更加可持续的包装解决方案。

The work aims to evaluate the carbon emissions of polypropylene recyclable packaging boxes and ironwood boxes across their entire life cycle,and investigate the environmental merits of polypropylene packaging boxes in comparison to traditional wooden boxes,so as to address a long-standing issue in the packaging of automotive components:"using plastics instead of wood"or"using wood instead of plastics".The Life Cycle Assessment(LCA)methodology was adopted to conduct a carbon footprint analysis with ironwood boxes as examples.It took into account the carbon emissions generated at each stage,from raw material acquisition,production,usage,to waste disposal.Through this rigorous approach,the environmental impact of packaging boxes throughout their life cycle could be accurately assessed to furnish a scientific rationale for choosing of future packaging materials.The findings revealed that polypropylene recyclable packaging boxes exhibited significantly lower carbon emissions throughout their life cycle compared with ironwood boxes.Specifically,ironwood boxes emitted approximately 571.265 kg,whereas polypropylene packaging boxes accounted for roughly a quarter of this figure.Based on these compelling results,it is evident that polypropylene recyclable packaging boxes effectively contribute to carbon emission reduction.Therefore,in the context of automotive component packaging,the adoption of"using plastics instead of wood"emerges as a viable and commendable option.This discovery serves as a valuable reference for the packaging industry,fostering the development of more sustainable packaging alternatives.
