Key factors influencing public awareness of household solid waste recycling in urban areas of China: A case study

With rapid economic development, population growth, and urbanization, household solid waste (HSW) causes significant environmental pollution and health threats to residents. As the sustainable waste management, HSW recycling is an urgent requirement in China and other countries. However, public awareness of HSW recycling and its influencing factors were seldom systematically analyzed in China. In present study, an on-site face-to-face questionnaire survey was the main research tool. We investigate public awareness of HSW recycling in typical Chinese cities, including public behavior, recycling knowledge, and public willingness to participate. The factors influencing public awareness were also explored. We found that public awareness was inadequate regarding HSW treatment behavior and recycling knowledge. Age is the most important sociodemographic factor influencing the public awareness of HSW recycling. White collar, residents with higher educational attainment, and those aged 20-50 years displayed less environmentally responsible behavior with regard to HSW treatment. Manual workers, those with lower educational attainment, those with higher monthly income, and older people tend to have poorer HSW recycling knowledge. White collar workers, those with higher educational attainment, and those with lower monthly income were less willing to participate in HSW recycling. Accordingly, measurements conducted amongst specific demographic categories are proposed to improve public awareness of HSW recycling. The scientific information provided by this study may contribute to HSW recycling especially from a public awareness perspective.
