Creation of a logic model for plastic resource circulation

Abstract

The marine plastic litter problem is recognized as a serious social issue. The purpose of this study is to create a logic model to illustrate how current activities could lead to the "long-term outcomes" (e.g., carbon neutrality and zero pollution from marine plastic waste). Interviews were conducted with local supermarkets, retailers, local governments, manufacturers, and industrial waste disposal companies, which were reflected in the creation of the logic model, and "negative impacts" that are assumed to occur as a side effect in the process of social change were also examined and attempted to be included (in gray) in the diagram.
