Plastic has many valuable applications and is found in several of the daily products we use. Yet, plastic waste is detrimental to the environment as well as can become life-threatening to humans, animals and marine life. The aim of this exploratory study is to examine the internal (knowledge of plastic waste, concern for the environment) and external factors (interpersonal influence and media) on attitude toward plastic waste. The study also examines the influence of attitude on behaviour related to plastic waste management. The respondents in this study were high school students in twelve schools located in various districts of Bangkok metropolis, Thailand. A total of 467 questionnaires were distributed, out of which 364 were considered valid for analysis. The three main hypotheses posited in the study were tested by multiple regression. The findings showed that all internal and external factors significantly influenced attitude; attitude in turn was also shown to significantly influence behaviour related to plastic waste management. The study concluded by offering several useful suggestions for better plastic waste management practices in the Thai context.
