In order to suppress the production and import of packaging that is difficult to recycle because of its material and/or structure, an additional rate has been imposed since 2021. However, the current system does not promote efforts by mandatory producers to increase recyclability because the premium is only applied only when recycling is considered to be difficult to achieve. Furthermore, the additional rate should be calculated according to consideration of the need to change the behavior of mandatory producers and the materials and structures used in packaging. Therefore, in this study, a premium plan for contribution to recycling was considered using various premium factors, and a premium plan using scoring was also considered. The additional rate was calculated as 15.0% for steel cans, 16.1% for aluminum cans, 25.4% for glass bottles, 16.2% for cartons, 25.8% for PET-colorless, 21.7% for PET-colored, 19.6% for PET-composite materials, 15.1% for foamed plastics for electronic, agricultural, food or other packaging, 15.4% for PSP, 20.3% for other synthetic resins (containers, trays, single-material PET), and 16.4% for composite materials including films and sheets. A scoring method was proposed on the basis of this evaluation.
