How does the presence of a plant influence waste sorting behaviour Op de Beke, Oskar; Luesomboon, Nutkamon; Baek, Brian; Lai, Tiffany; Roh, Jasmine

Abstract

This study aims to investigate whether the presence of a plant near indoor waste disposal bins impacts correct waste sorting. We hypothesized that participants exposed to a plant, as opposed to those in the control conditions, will have a higher percentage of items sorted correctly into disposal bins. By employing a convenience sampling method, we included 167 participants in our study. We observed participants in one of the following conditions: a no-object control condition, a green flag control condition, and a plant condition. During the observation, we recorded the total number of items each participant disposed in each bin, as well as the number of items correctly and incorrectly sorted. Contrary to our hypothesis, the plant did not significantly improve waste sorting when compared to control conditions. Participants in the plant condition had the lowest average percentage of items sorted correctly, followed by those in the no-object condition and then the green flag control condition. However, mean comparison and marginal significance point to the possibility that a green flag may improve waste sorting. Implications and recommendations for UBC regarding the application of the plant and the flag are also discussed.
