Understanding residents’ behaviour intention of recycling plastic waste in a densely populated megacity of emerging economy
AI summary Read the abstract
This study surveyed 577 residents of Dhaka, Bangladesh, finding that moral norms — personal ethical obligations — were a stronger driver of plastic recycling intentions than social norms, and that perceived gaps in knowledge and policy support paradoxically increased recycling motivation even as they reduced perceived control over behavior.
Plastic waste is choking our planet, but the recycling rate is still universally low. Understanding factors affecting recycling behaviours can help address this pressing issue. Taking Dhaka as an example, this study explores the determinants of the intentions to recycle plastic waste. We employed the Theory of Planned Behaviour (TPB) and extended it with two additional variables: Moral Norms, and Perceived sufficiency of knowledge and policy support. Survey data of 577 were collected and analysed using PLS-SEM. The findings suggest attitude, perceived behavioural control, moral norms and subjective norms significantly impact recycling intention, among which moral norms (β = 0.148, p < 0.05) acts even more strongly than subjective norms (β = 0.12, p < 0.05). Moreover, low level perception of knowledge and policy support makes people perceive less control over recycling behaviour (β = 0.188, p < 0.05), but actually reinforce their recycling intention (β = -0.091, p < 0.1). This study enriches the theoretical discussion of TPB, and contributes to the efforts of encouraging plastic recycling in populated megacity of emerging economy.

This study applied the Theory of Planned Behavior to model plastic recycling intentions among residents of Semarang, Indonesia, finding that positive attitudes and social norms significantly boosted recycling intent, while perceived behavioral control had minimal impact on actual behavior, pointing to awareness and resource gaps as the key barriers.
Sustaining responsible plastic usage behavior to promote circular economy through the extended TRGP model: Evidence from a developing country
AI summary Read the abstract
This study looked at what actually motivates people in Dhaka, Bangladesh to cut down on plastic use and dispose of it properly, finding that personal drive and a sense of moral duty matter more than just having convenient recycling options. Since plastic pollution breaks down into microplastics that end up in our water, food, and even our bodies, understanding how to inspire real behavior change (not just good intentions) is a key piece of reducing our long-term exposure to these particles. The takeaway: policies that tap into people's sense of personal responsibility may work better than those relying on convenience alone.

AI summary Read the abstract
This study surveyed 140 consumers in Bandung, Indonesia using the extended Theory of Planned Behavior, finding that personal attitude and perceived behavioral control were the strongest predictors of intention to reduce single-use plastic bag use, while subjective norms, environmental awareness, and regulations did not significantly influence behavior, suggesting demand-side and supply-side interventions are both needed.
The Role of Awareness of Consequences in Predicting the Local Tourists’ Plastic Waste Reduction Behavioral Intention: The Extension of Planned Behavior Theory
AI summary Read the abstract
Researchers surveyed local tourists in Jeddah, Saudi Arabia to understand what drives intentions to reduce plastic waste on beaches. The study found that awareness of environmental consequences, social norms, and perceived behavioral control all positively influenced intentions to reduce plastic waste. Interestingly, personal attitude alone was not a significant predictor, suggesting that community influence and awareness campaigns may be more effective than individual mindset shifts.
