The Study of Population’s Behaviors in Using and Littering Bioplastics in Bangkok

Abstract

 This research aims to study the perceptions influencing the behaviors in using and littering bioplastics and analyze the population's behaviors in using and littering bioplastics in Bangkok through Gibson's Field Theory. The theory, consisting of knowledge, experience, intellect, and environment, leads to suggestions on the method for consumers' behavior change and perception regarding bioplastics. It can solve the current environmental issues better. Close-ended questionnaires developed from Gibson’s Theory of Direct Perception were used as a data collection tool. Data were analyzed using inferential statistics consisting of (1) Independent T-test, (2) One-Way ANOVA, and (3) Multiple Linear Regression. To analyze the correlation of perception factors and behaviors in using and littering bioplastics of the sample population in Bangkok of 3 areas (Inner area, Central area, and Outer area) of 85 using G*Power for calculation.

The study found that the differences in sex, age and education level impact the behaviors in using and littering bioplastics, sometimes resulting in micro-plastics is statistically significant at .05. The differences in status, occupation, and members living in the same household influence the behaviors in using and littering bioplastics resulting in no micro-plastics is statistically significant at .05. The difference in income influence the behaviors in using and littering bioplastics and resulting in no micro-plastics is statistically significant at .05. Furthermore, according to Gibson's Theory of Direct Perception in intellectual effects the population's behaviors in using and littering Bioplastics in Bangkok the most.
