Using the Theory of Planned Behavior (TPB) as its framework, this study explores consumers’ adoption of circular economy (CE) principles. The impact of attitudes, subjective norms, and perceived behavioral control on consumers’ intentions to engage in CE practices was examined in this research. A mixed-method approach was used where data were collected from 100 respondents from different demographic groups. Quantitative analysis of data revealed a strong correlation between positive attitudes towards CE and behavioral intentions, while familiarity with CE concepts emerged as a critical factor influencing both attitudes and intentions. Qualitative findings highlighted economic and accessibility barriers that hinder the translation of intentions into actions. Demographic factors such as education and income showed minimal influence, underscoring the importance of awareness and access. The study concludes that fostering familiarity with CE principles through education and reducing economic barriers are essential for driving broader CE adoption. Recommendations include educational campaigns, financial incentives, and improving infrastructure to support circular consumption practices.
