The acceleration of growth in the population in Saudi Arabia and the increase in municipal solid waste generation have caused a problem in Dammam city: an increase in solid waste production. Therefore, solid waste sorting is an important practice of municipal solid waste management. The main objectives in this research are understanding the effect of internal and external factors on household willingness in sorting waste in Dammam city and studying the attempts to construct a theoretical research model by adding market incentives, government facilitators, and awareness into the popular planned behaviour theory to explain residents' waste sorting intentions. The data collection and analysis are based on the questionnaire study, which is based on the questionnaire survey data from 450 households in Dammam. This study revealed that social influence significantly predicts households' willingness to sort and recycle, that is, to promote recycling. Additionally, the variable social influence has a significant but low influence on households' willingness to sort and recycle. The result of the structural equation model shows that perceived behavioural control significantly predicts households' willingness to sort and recycle waste. This finding is consistent with the theoretical expectation. Therefore, this research shows that attitude, social influence, perceived behavioural control, market incentives, government facilitators and awareness positively and significantly affect residents' waste sorting intentions. Additionally, this research corroborates the discrepancy between internal and external variables.
沙特阿拉伯人口增长的加速和城市固体废物产生量的增加，导致达曼市出现了一个问题：固体废物产量增加。因此，固体废物分类是城市固体废物管理的一个重要实践。本研究的主要目的是了解内部和外部因素对达曼市居民垃圾分类意愿的影响，并研究通过将市场激励、政府促进因素和意识纳入流行的计划行为理论来构建理论研究模型的尝试，以解释居民的垃圾分类意愿。数据收集和分析基于问卷调查研究，该研究基于达曼 450 户家庭的问卷调查数据。本研究表明，社会影响显著预测了家庭进行垃圾分类和回收的意愿，即促进回收。此外，社会影响这一变量对家庭进行垃圾分类和回收的意愿有显著但较低的影响。结构方程模型的结果表明，感知行为控制显著预测了家庭进行垃圾分类和回收的意愿。这一发现与理论预期一致。因此，本研究表明，态度、社会影响、感知行为控制、市场激励、政府促进因素和意识对居民的垃圾分类意愿有积极和显著的影响。此外，本研究还证实了内部和外部变量之间的差异。
