Abstract
Individual’s attitude & behaviour is crucial for implementing sustainable construction & demolition (C & D) waste management, however it is often underachieved. The present article explores the motivators of workforce towards implementation of construction waste management (CWM) in India. A hypothetical model using theory of planned behaviour (TPB) is framed fundamentally by incorporating constructs such as knowledge and perceived usefulness. The extended TPB (ETPB) model is then tested via structural equation modelling which utilizes, empirical data from construction workforce in India for the analysis. The analysis results conclude, perceived behaviour control is consistently crucial construct for predicting behaviour intention in comparison with attitude and subjective norm. The additional constructs Knowledge has significant behavioural impact on implementation of CWM, and the impact of subjective norm and perceived usefulness are insignificant. The study is pertinent to: (i) policy makers — for establishing regulations & practices, (ii) corporates — for devising effective approaches, (iii) academia — for encouraging attitude and behavioural changes towards implementation of CWM.
