Abstract

This study focused on the waste separation behavior of households in areas with a waste separation at source (WSS) program to understand the effect of the program and identify suggestions for improving the participation rate. A questionnaire survey was conducted through face-to-face interviews with 402 households in Da Nang City, Vietnam. To measure the effect of the WSS program on waste separation behavior, the authors conducted a comparison between waste separation behavior before and after implementing the program. The authors developed a model of waste separation behavior to clarify the factors. The differences in participation rates and influencing factors as they related to respondents’ level of involvement in the WSS program were also examined by Chi-squared test and ANOVA. The participation rate before the WSS program was 70.0% for plastic bottles, 70.1% for cardboard, and 71.4% for aluminum cans. After the WSS program, these rates significantly increased by 14.2% for plastic bottles, 12.6% for cardboard, and 12.3% for aluminum cans. Through behavior modeling, the factors influencing waste separation behavior were clarified. The attendance of respondents at an explanatory meeting and the recognition of the leaflets would positively promote the participation rate and the factors influencing waste separation behavior.

在越南岘港市评估源头废物分类计划的效果

摘要

这项研究的重点是采用源头废物分类（WSS）计划的地区的家庭的废物分类行为，以了解该计划的效果并确定提高参与率的建议。通过对越南岘港市的402户家庭进行面对面访问，进行了问卷调查。为了衡量WSS计划对废物分类行为的影响，作者对实施该计划前后的废物分类行为进行了比较。作者开发了废物分离行为模型以阐明因素。卡方检验和方差分析也检验了参与率和影响因素与受访者参与WSS计划的程度之间的差异。WSS计划之前的参与率为70。塑料瓶为0％，纸板为70.1％，铝罐为71.4％。在实施WSS计划后，塑料瓶的使用率显着提高了14.2％，纸板的使用率显着提高了12.6％，铝罐的使用率显着提高了12.3％。通过行为建模，明确了影响废物分离行为的因素。受访者参加解释性会议和认可传单将积极提高参与率和影响废物分类行为的因素。
