Survey on Perceptions of Residents around a Solid Waste Incinerator

Background: Solid waste incinerators (SWI) impact surrounding residents’ health, mental well-being, property values, and community image. Despite efforts by authorities to address conflicts, negative perceptions of SWI persist. Objectives: This study aims to examine satisfaction with the surrounding environment and perceptions of SWI operation among residents at varying distances, providing data to improve public perceptions in the area. Methods: The study focused on an region around a SWI divided into three areas based on distance in one direction: Area A (<0.5 km), Area B (0.5~3.0 km), and Area C (3.0~6.0 km). A survey of 1,400 residents (A=600, B=400, C=400) included questions on sociodemographic characteristics, environmental satisfaction, perception of the environmental, health, psychological, economic impact of the SWI, its operation, and information sources. Responses to each survey item were categorized by area and then frequency, percentage, mean, and standard deviation were calculated. Chi-square test, Kruskal-Wallis test, and Spearman’s correlation analysis were performed to compare significant regional differences in the survey results (SPSS 29.0.2.0). Results: Satisfaction with the surrounding environment was lower in the area closer to the SWI. Residents of this area were more sensitive to air pollution and odors, perceiving the SWI as a source of psychological stress and economic hardship. Residents felt that the lack of information and insufficient efforts by local authorities increased distrust. A “Resident Support Committee” provided information to residents in the nearby area, while other residents relied on informal sources. Use of the city hall website was low in all areas. Conclusions: This study suggests that the issue of residents’ perceptions regarding the operation of SWI needs to be addressed. Therefore, local authorities have to enhance transparency, regularly disclose updates on SWI operations, and establish communication systems to rebuild trust with residents. Efforts are also needed to more actively incorporate residents’ opinions and engage in various initiatives.
