The study on residents' choice of solid waste sorting measures by pivotal statistics and structural equation model

Domestic solid waste (DSW) sorting was the core task of waste-free city buildings. Implementing domestic solid waste sorting measures that residents were willing to accept, was an effective way for municipal solid waste management. This study used online questionnaires which investigated 777 adults across China to research the residents' choices and the influence factors. Pivotal statistics method and structural equation model were used to analyze the main factors and their impact levels on 4 target variables, such as "expected distance from DSW disposal point". The results showed that age obviously determined the residents' choice of these 4 target variables to a large extent. At the same time, the residents' DSW sorting willingness was also greatly affected by the corresponding external factors. Finally, the study put forward relevant recommendations for the comprehensive management of urban DSW sorting and recycling at the community level. The study may play an important role in promoting domestic solid waste sorting.
