Assessment of awareness, consensus, and willingness to enforce regulations’ household waste separation in Ho Chi Minh City, Vietnam

Abstract

The amount of household solid waste is increasing seriously in Vietnam, because of population growth, urbanization, and economic growth. Reducing the waste volume liberated to the environment needs community participation and people’s awareness about the waste segregation at sources and hand to reuse and recycling. Realizing the value of waste classification would mobilize residents to classify domestic waste and nurture more residents’ habits. Knowing the factors influencing the individual waste separation intention supports building effective environmental campaigns. By applying the Theory of Planned Behaviour (TPB), this study determined factors correlated with residents’ waste classification intention in Ho Chi Minh City (HCMC), Vietnam. An extension of the TPB model was undertaken. This extension incorporated three additional factors, namely, propaganda, awareness, and consensus about household waste separation regulations to predict individual separation intention in HCMC, Vietnam. With a sample size of 250 residents, SPSS 20.0 software is used to analyze data. This study supports policymakers regarding formulating laws and regulations in terms of raising waste classification intention and community recycling plans.
