Recycling has a positive impact on the retrieval of secondary raw materials and reduces greenhouse gas emissions (European Commission, 2014). However, only 49% of the municipal waste was recycled and composted in the Netherlands in 2012 (European Environment Agency, 2015). The aim of the European Union is to increase this number to a minimum of 70% by 2030 (European Commission, 2014). Research indicates that both individual factors (e.g., personal and social norms, recycling attitudes; Schultz, 1999; Schwab, Harton, & Cullum, 2014) and contextual factors (e.g., collection system, local circumstances; Hage & Soederholm, 2007; Schultz, Oskamp, Mainieri, 1995) affect recycling behaviour. Yet, research on recycling behaviour has mostly examined the influence of these factors separately. In this PhD project, we will study how individual and contextual factors interact in affecting people’s recycling behaviour. We propose that it is essential to explicitly consider the psychological implications of contextual factors, and the interplay of individual and contextual factors in order to understand individuals’ recycling behaviour. This is especially relevant in the Netherlands where many different collection systems exist. Thereby, this PhD project will make the goal to reach recycling rates of 70% by 2030 more feasible.
