As a results, the factors for recycling behaviors of drop-off collection of PET bottles were extracted as “Interest of recycling” and “Behavior of other citizens”, and the distance to the collection point also influences the factors. In the improvement of the collection rate, measures of the improvement of environmental awareness are more effective than measures of the infrastructure of an increase of the number of collection points etc. Furthermore, the effect was measured as cooperation rate to the drop-off collection.
