Composition and flow survey for planning plastic management measures on Okinoerabu Island

Abstract

It has been a long time since the plastic problem became a global and local social issue. Measures to solve the problem are being considered and introduced in various places, but one of the places where it is difficult to solve the problem is island regions/countries. This is true of waste and resource circulation in general, but in addition to the fact that stranded garbage cannot be ignored, the small population size makes it difficult to achieve economies of scale such as recycling, and there are significant restrictions on off-island processing, such as high transportation costs. It's for a reason. This time, we used a resin discrimination sensor to conduct material analysis and weight analysis of beach-washed plastic and general waste plastic on Okinoerabu Island. Based on these analysis results, we will examine the possibility of future circulation within the island and the possibility of suppressing its occurrence.
