Recent decades have witnessed a sharp
increase in the amount of household waste
generation worldwide, which inevitably
brings about serious environmental
problems and exposes sustainable
urbanism to overwhelming challenges.
China, as the most rapidly industrialised
and populous country, is undeniably the
largest household waste producer,
generating about 200 million tonnes of
household waste per year. Since the 21st
century, China has been promoting to
separate and collect household waste at
source, however, household waste sourceseparated
collection programmes in China
are still in the initial stage and there is little
literature on household waste management
in the research context of China. To fill this
gap in literature and to provide pragmatic
implications for policymakers in Nanjing, a
20-person pilot interview and a self-report
questionnaire survey with a sample size of
449 are conducted in Gulou District,
Nanjing, adopting the TPB+ model I
construct. The results of data analysis show
that the 10 policy-related factors in the
TPB+ model all have significant impacts on
Nanjing residents' household waste source separated
collection behaviour. Among
them, environmental knowledge and
awareness towards environmental
problems, social/community atmosphere, publicity, policy clarity, accessibility to facilities serve as the five best predictors, suggesting that attitudes, subjective norms, perceived behavioural control and normal norms are significant determinants of Nanjing residents' household waste source-separated collection behaviour. By contrast, the predictive validity of situational factors is relatively mild. Based on the findings, this dissertation further provides several relevant implications for the Nanjing government.
