Plastic Use Among Sri Lanka's Metropolitan Population: A Study of Environmental Consciousness and Behaviour

Abstract

This study seeks to evaluate customers' purchase and disposal patterns for plastic and polythene and whether their environmental consciousness matches with actual behaviour. Data were collected from 117 households in metropolitan areas in Sri Lanka and analysed using descriptive statistics and paired sample t-test. Before data analysis, the scales' reliability and validity were evaluated. Findings showed a significant gap between actual behaviour concerning plastic consumption and environmental consciousness. Although most customers have positive opinions regarding environmental awareness, these beliefs have not necessarily converted into the corresponding behaviour to the same degree. As per results, 39% of the respondents burn their waste, including plastics, in open, while 4% have engaged in open dumping. The findings of this study can be taken into consideration to minimize the harmful effects of plastic and polythene disposal behaviour in Sri Lanka through an understanding of consumers’ actual behaviours. Especially relevant authorities shall initiate awareness campaigns and proper garbage disposal systems.
