Effective information provision to formalise disposal behaviour in home appliance recycling Recent collection rates of End of Life home appliances from consumers (generators) hover around 60% - 70% in Japan. Hence, formalising disposal behaviour of consumers is an indispensable element for further enhancement of the overall recycling performance. Weighing behavioural factors depends on the case and the prior knowledge of it. Moreover, previous studies show that there is room for further improvement in consumers’ knowledge of the home appliance recycling. In this study, an online questionnaire survey was carried out in order to estimate effect of promoting the formal disposal on behavioural factors, chiefly behavioural intention, by information provision. In prior to answering the questions, respondents (n=840) were randomly allocated to three groups regarding prior knowledge: a group with no prior information (reference group, n=416), a group provided with procedural information (n=212) and a group provided with declarative information (n=212). In this study, Azjen’s Theory of Planned Behaviour is employed as the decision-making model. The path coefficients and loading factors are estimated by structural equation modelling. Results reveal that acquiring declarative knowledge has more positive impact on behavioural intention of formal disposal in accordance with the recycling scheme.
