Why do Spanish households separate their e-waste for proper disposal? An econometric analysis

Abstract

Improving e-waste separate collection rates is of the utmost importance to achieve the environmental targets set in the Sustainable Development Goals. Therefore, this paper aims to identify the factors influencing the intentions of Spanish households to separate their e-waste for proper disposal. To this end, we carry out an econometric analysis revealing that the preoccupation with environmental issues is an endogenous regressor, so a bivariate model is required to avoid inconsistent results. The analysis shows that environmental concern and the origin of the individuals are relevant factors that influence the e-waste separation decision. Additionally, we observe an interaction between age and city size, so the effect of one of these factors on the probability of separating e-waste depends on the other factor. Another important result is that several socio-economic variables and knowledge of environmental issues only indirectly affect attitudes, by way of environmental concern. In summary, this study offers a useful methodology to policymakers who have to deal with e-waste management, allowing them to identify the priority groups on which should be focused, as well as to design specific measures tailored to their characteristics.

The Impact of Penalty on Residents’ Waste Separation Behavior: A Moderated Mediation Model

“…First, many studies explored the influence of individual motivational factors on residents' WSB based on the theory of planned behavior and normative activation model [13][14][15]. The results showed that individual motivational factors, such as attitude toward waste separation, environmental concern, institutional trust, and awareness of consequences, positively affected residents' WSB [16][17][18]. However, a few scholars held a different view.…”
