An increase in solid waste production may affect sustainable solid waste handling practices such as indirect disposal and sanitary landfilling. The objective of this study was to explore the possibility of Dammam residents’ participation in sorting and recycling by comparing sustainable waste handling practices from different income level groups according to family income levels to determine the impacts of independent variables on the willingness of residents to participate in sustainable waste handling practices. There was a statistically significant difference between low and high levels of awareness and perceived behavior control in Dammam City households’ willingness to sort waste and recycle; however, at the middle level, there was only a significant difference in perceived behavior control. Moreover, there was a statistically significant difference between high and middle levels in government facilitators regarding sorting and recycling willingness in Dammam City. The descriptive analysis comprised 450 participants (37.8%) in middle levels, (44.2%), high levels, and (18%) low levels. The results of the participants’ attitudes consisted of sorting (57.1%) and recycling (55.1%), as well as awareness (46.9%) and sorting and recycling (47.1%) in high-income levels.
