Study on solid waste behaviour by structural equation modeling (SEM) - a mini review

Abstract

This paper aimed to present a mini review on applying Structural Equation Modeling (SEM) for behavioural research on solid waste management. This paper examined the literature on behavioural research of solid waste management across various geographical regions. Households were the ubiquitous research subject of the studies on waste separation behaviour, while business sectors - accounting for a large amount of waste generation - were not pervasively studied. Theory of planned behaviour (TPB) was the dominant theory model for studies on waste separation behaviour. However, waste separation behaviour would be extremely complex so base theory integration was highly recommended. Five-point and seven-point Likert scales were the most ubiquitous scales utilised. PLS-SEM would be a “Silver bullet” due to its advantages in data analysis. The results of this study are expected to be a reference for managers, decision-makers, policymakers, researchers, and other stakeholders in solid waste management studies and projects.
