More than just organics: Boosting separate collection of dry recyclables with door-to-door bio-waste collection in EU capitals

Abstract

The European Union Waste Framework Directive revised in 2018 sets an ambitious target of recycling 55 percent of municipal solid waste by 2025. Separate waste collection is an important prerequisite for achieving this target, but progress is uneven among Member States and has slowed down in recent years. This makes it paramount to identify effective waste management systems to enable higher recycling rates. Waste management systems vary greatly within Member States and are established by municipalities or district authorities, making the city-level the ideal level of analysis. Based on quantitative analysis of data from 28 European Union capitals (pre-Brexit), this paper speaks to debates about the effectiveness of waste management systems more broadly and the role of door-to-door bio-waste collection in particular.Drawing on encouraging findings in literature, we investigate whether door-to-door bio-waste collection contributes to boosting the collection of dry recyclables such as glass, metal, paper and plastic. Employing Multiple Linear Regression, we sequentially test for 13 control variables including six related to different waste management system and seven controls related to urban, economic and political aspects. We find evidence that door-to-door bio-waste collection is associated with greater amounts of separately collected dry recyclables. Cities with door-to-door bio-waste collection, on average, sort 60 kg per capita per year more of dry recyclables. Although the causal mechanisms behind such a relationship need further investigation, this finding indicates that European Union waste management could benefit from a stronger promotion of door-to-door bio-waste collection.
