Enabling circularity: Analysis of factors influencing MSW sorting behaviour in Central Norway

Abstract

A comprehensive waste composition analysis was undertaken in 2021, covering ten municipal waste companies in Central Norway. The results are used in a multiple linear regression model to explore factors influencing the municipal solid waste sorting behaviour. The aim of the study is to better understand what affects waste sorting, to aid in the progress of achieving circular economy targets. The share of food waste and mixed waste in the mixed waste bin is analysed considering three variables: Food waste collection system, glass and metal packaging waste collection system and type of settlement. The waste collection systems are found to have a significant effect on the sorting behaviour, where the possibility for sorting and the user-friendliness and transparency of the sorting system are important factors. Type of settlement is not found to have a significant effect on the sorting behaviour. We recommend further in-depth studies to confirm and expand on the findings in this study, and to better utilise the potential of waste composition analyses to enhance understanding of waste sorting behaviour. This understanding is crucial to reach a more circular waste system.
