Improper handling of household solid waste causes problems that affect public health and the environment, as well as the aesthetic nature of cities. This paper aims to determine if the theory of planned behavior (TPB), and its extended version can be used to predict household recycling intention (RI), and whether perceived lack of facilitating conditions have a moderating role on households’ RI in Nigeria. Data from a sample of 393 households from Kano metropolis Nigeria were analyzed using structural equation modeling. The result reveals that the TPB Model predicts households RI in Nigeria and explains 42% of the variance in RI. Attitude is the most important predictor of RI in the TPB model (β = 0.593, p = 0.000). However, after personal norm (PN) was added into the model, the variance in RI increases to 58% and PN becomes the most important predictor of RI in the extended TPB model (β = 0.496, p = 0.000). Perceived lack of facilitating condition was found to have a significant moderating effect on households’ RI. Finally, our findings show that providing households with recycling facilities and local collections holds great promise for improving households’ intention to recycle.

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. In perceived behavior control, the participants’ results were 47.7% for sorting and 49.6% for recycling in the middle level. Regarding, MI, SI, and GF, the participants’ results in the high-income levels were greater than the others (44.2%, 51.1%, and 57.1%, respectively) toward sorting and recycling. Only awareness between low-income and high-income groups and between the middle-income and high-income groups was significant; therefore, it was supported in some instances and not in others.
