Abstract
Plastic products have excellent functionality and are very convenient, but they are deeply involved in problems such as marine pollution and global warming. In order to deal with these problems, efforts have been made in recent years to replace disposable plastic products with others. As a previous study, the environmental impact of substituting paper products for some disposable plastic products was evaluated by life cycle assessment, but expansion of the target products and more detailed analysis were issues. In this study, we expanded the target products and analyzed using MiLCA and the latest LCA data (IDEA ver2.3) . Weighed and set the weight of plastic products and paper products (including the setting of coating with plastic), and used the data of the corresponding process. As a result, for many products, paper products were superior in the evaluation items of "climate change", "resource consumption", "photochemical oxidant", "human toxicity", and "energy consumption", but "waste", "eutrophication", and "enrichment" Paper products were inferior in evaluation items such as "ecotoxicity", "water resource consumption", and "land use".
