The aim of the present study was to evaluate the knowledge, attitude and practice (KAP) of Tabriz citizens to participate in recycling.
Material and Methods: This cross-sectional study involved 450 samples, in three different regions of Tabriz with high, average and low income levels (150 from each district), selected by systematic sampling. The relevant data were collected by questionnaires and were analyzed in SPSS and Excel software. 
Results: The results of this study showed that the majority of Tabriz citizens had acceptable information about waste and recycling. Average knowledge, attitude and practices of the various regions were 86.8%, 75.6% and 59% respectively. There was no significant association in this field in three different regions (p.value > 0.05). Comparing the regions, education and welfare of the residents had no effect on the willingness to participate in recycling programs.
