Comparison of life cycle assessment for takeout meal packaging (kraft paper bowl and plastic bowl) based on Simapro

Abstract

Purpose This study aims to compare and analyze the impact of the commonly used takeout packing (Kraft paper bowl and plastic bowl) through life cycle assessment, then certain suggestions for the development of green packaging could be provided. Design/methodology/approach In this study, Simapro software was used to calculate and analyze the whole life cycle of takeout packaging from the stage of raw materials, production and processing and waste disposal. Findings Twelve environmental categories were used to quantitatively analyze the environmental impact of the two different bowls. The results showed that the impact of Kraft paper bowl on the environment was less than that of plastic bowl, regardless of raw material, processing or waste stage. Kraft paper bowl was better than plastic bowl. Research limitations/implications This study compared and analyzed the progress of 750-mL bowls made with different materials and specific specifications. Practical implications Green packaging is the development trend of the future packaging and follows the principle of reduce, resue, recycle, degradable. According to the calculation results, corresponding suggestions can be put forward from production, processing, use, waste and other aspects, and make corresponding contributions to the development of green packaging. Originality/value The contribution and impact of each stage of the product on the environment can be studied. The environmental impacts, such as global warming potential and water scarcity, can be reduced through different solutions, such as the use of green materials, good processing techniques and higher recycling rates.
