PET (Polyethylene Terephthalate) waste is a crucial problem because of its high consumption as disposable packaging. Even used PET plastic is the most accessible type of plastic to recycle. So, recycling PET plastic waste is a solution to the problem of plastic waste that contributes to environmental safety while providing economic benefits towards a circular economy. In a circular economy, the consumer is the initial entity producing waste to be recycled. So that consumers can act as suppliers in reverse logistics, this study aims to analyze consumer behavior after PET consumption in terms of economic, social, environmental, and regulatory aspects. This study was conducted with a survey on household consumers with residence, education, and income variables. The survey results were presented using descriptive statistics, and the relationship between the variables was tested using the Chi-Square test. The survey results show an association between residence, education, and income variables with post-consumption consumer behavior. This research contributes to determining consumer behavior, leading to increased consumer engagement in the return of waste products in reverse logistics through implementing policies.
