Evaluation of models for household recycling behaviour in high-rise buildings: A Chinese case study in urban Guangzhou.

Abstract

Recycling strategies and waste management for the source separation of recyclables are still in their infancy in China and many other developing countries. Unlike formal recycling systems with strictly regulated management in high-income countries, waste management and recycling activities in low-income and middle-income countries are predominantly informal. Formal recycling systems often have very small amounts of recyclables in comparison to informal recycling systems. Considering the Chinese case of urban Guangzhou, where formal and informal recycling systems coexist, this study investigated household recycling behaviour and explored the sociodemographic and contextual factors that affect this behaviour. Based on data collected through questionnaire surveys and interviews, a model of the use of public recycling facilities (UPRF) and a model of the use of informal recycling sectors (UIRS) were evaluated using correlations and multiple regression analyses. The findings indicated that the use of public recycling facilities can be significantly predicted by the launch of a source separation scheme, the physical setting and satisfaction with public recycling facilities. The sociodemographic variables did not significantly predict the use of public recycling facilities but did significantly predict the use of informal recycling sectors. This study's findings have implications for researchers and policymakers and shed light on public designs for sustainability.
