7. Conclusion
This study found that differential policy support exists across different waste management instruments in Hong Kong, with recycling infrastructure and extension of PRS are most welcomed by the majority of respondents while MSW charging scheme is least supported. Conforming with prior studies, gender, age, and education level significantly associate with policy support across waste management options. The investigation suggests that uncoordinated and fragmented waste management framework account for the ineffectiveness of measures and, in turn, the patterns of policy support. In view of this, a coherent and complementary waste management framework was constructed based on the results and discussion. Different from other proposed frameworks which emphasize the hierarchy and priority of waste policy (e.g., Triguero et al., 2016; Xiao et al., 2017), this framework brings attention to the complementary nature of different policy categories and highlights the mechanism of mutual reinforcement between policies. The findings provide policy-makers with evidence for waste management policy formulation and implementation. The research contributes to current literature of waste management in cities which share similar background with Hong Kong. The demographic effects on policy support and proposed coherent waste management framework add valuable reference to existing literature. The present study is also relevant to waste management discussion of many other cities as findings are based on analysis of a broad range of common waste management policies.
