Background: Nowadays, one of the most serious environmental concerns is the appropriate management and disposal of municipal waste, which can lead to significant environmental consequences. This study aimed to examine the determinants of source waste separation behavior (SWSB) among high school students applying the theory of planned behavior (TPB). Methods: In this descriptive study that was performed in 2022 via an online survey, 689 questionnaires were completed by students in 10 randomly selected high schools in Abhar, Iran. The data were analyzed by IBM SPSS Amos version 23. To assess the predictive determinants of SWSB, a structural equation model (SEM) was used. Results: Subjective norm was found to be the best predictor of high school students' source waste separation (SWS) intention. The TPB had a prediction power of 68% and 74% for predicting waste separation from the source intention and behavior, respectively. Conclusion: According to the results of this study, subjective norm has the greatest impact on separation intentions (regression weight = 0.550; SE = 0.08; CR = 6.863; and P < 0.0001). Educational administrators are suggested to pay special attention to the role of significant others, such as teachers, parents, and peers in their planning to improve waste separation behavior at the source in schools.

This research goes beyond the attitude-intention link to investigate the determinants of solid waste management behavior among the student community. The study proposes an extended model comprised of constructs from psychological frameworks, the theory of planned behavior and value-belief-norm theory by integrating environmental knowledge and situational factors as the intrinsic and sextrinsic variables. A self-administered questionnaire method with a sample of 1,105 and structural equation modeling to test the statistical significance of the model revealed that our novel model includes a satisfactory level of prediction power, which is superior to existing theories. Findings show that intention, subjective norms, perceived behavioral control and attitude had a significant positive influence on behavior. While biospheric and altruistic values showed positive relationships with belief, moral norms and environmental knowledge was found to be crucial in forming attitude. The results of this work could be used by governments, policymakers and researchers to design and implement effective waste management systems.
Key Determinants of Waste Separation Intention among Students on Campus
MATEC Web of Conferences, 2016
This study aims to identify the key determinants of waste separation intention among the students in Universiti Teknologi Malaysia (UTM). As reported in World Bank Report, generation of global municipal solid waste are approximately 1.3 billion tonnes per year, and it will increase approximately 2.2 billion tonnes per year by 2025. Similar trend in Malaysia which approximately eight million tonnes of municipal solid waste is produced daily. Upward trend of the solid waste generated is contributed by various forces including growth, increase of population, residents attitude and rapid urbanisation in the country. Considering the negative impacts from increase of waste generated in the country such as environmental degradation, separate the waste at its source can increase recycling rate and hence reduce waste generation. In the 11 th Malaysia Plan, the government has urged the nation to actively practice waste separation. Understanding the determinants influencing waste separation behaviour can lead to effective waste reduction among the targeted group. This study adopted the Theory of Planned Behaviour as the fundamental framework. The key determinants of waste separation behaviour are attitude, subjectives norm, and perceived behavioural control. An elicitation survey has been conducted to explore the students's beliefs relative to the waste separation behaviour. The empirical data collected were analysed using structural equation modelling (SEM) assisted by SmartPLS software. The result shows that only determinants are significant towards intention which are attitude and Perceived Behavioural Control while Subjective Norm is not. The results of the study is significance to the organisation as identification of the determinants that influence waste separation intention contributes to a more focused waste separation programme that allign to Malaysia's objective towards a sustainable developing country.

In China, governments are promoting waste management as an urgent environmental issue. Hangzhou is one of eight cities in China that have launched a pilot run for household waste separation since 2010. The government survey and a previous study of the authors have confirmed the gap between citizens' positive attitudes and their real behavior related to waste separation. In our study, the theory of planned behavior (TPB) is applied to analyse the factors that could influence the behavioral intention of the citizens towards separating waste. The structural model based on TPB was constructed to represent the framework of the citizens' intentions related to their waste separation behviour, based on a pilot survey and expert interview. Following the model, a 211-sample questionnaire survey was designed and conducted in Hangzhou. 19 extracted factors are categorized and structured following TPB. The result shows: attitude, subjective norm, and perceived behavioral control have positive influence on behavioral intention; perceived behavioral control exerts stronger influence than the other factors. Based on the findings, this study discusses policy implications and recommendations for improving the current policy and the situation of household waste separation.
Investigation of Attitudes and Behaviors Towards Recycling with Theory Planned Behavior
Journal of Economy Culture and Society
Recycling is defined as the re-inclusion of wastes that can be reused in the production process by undergoing various processes. At the same time, recycling is seen as the most important environmental behavior that reduces the amount of solid waste and conserves resources. Considering the importance of recycling for a sustainable future, it is of great importance to determine the factors affecting the recycling behavior of individuals. Due to the rapid increase in environmental problems and their extremely negative impact on life, it is necessary to determine the environmental and recycling behaviors of individuals and produce solutions. In this study, attitudes and behaviors towards recycling were investigated with the help of a model proposed within the scope of Theory Planned Behavior (TPB). The analysis of the data was made using the Partial Least Squares Structural Equation Modeling (PLS-SEM) Smart-PLS software, which can be used successfully in small-volume samples and does not require the assumption of multivariate normality. It was determined because of PLS-SEM fit criteria that TPB is suitable for explaining recycling attitudes and behaviors. As a result of the analysis, it was revealed that attitude, subjective norm, and perceived behavioral control positively and significantly affect recycling intentions.

In Malaysia, recycling program has been widely initiated since 1993. However, to date the recycling rate in Malaysia is only five percent. In this study, the Theory of Planned Behaviour (TPB) was used to investigate the antecedents of recycling intention behaviour among secondary school students. TPB hypothesizes that the immediate determinant is the individual's intention to perform or not to perform that behaviour. Hypothetically, there are three factors that influenced the intention behaviour namely specific attitude, subjective norms and perceived behaviour control. The sample consists of 400 randomly selected Form Four students. A two-step modeling approach including confirmatory factor analysis and structural equation modeling were performed to assess measurement model fit and causal relationship between factors. The structural model was tested using AMOS. The proposed model was evaluated but demonstrated poor model fit which lead to subsequent modification of the model. The result shows that perceived behaviour control was the strongest predictor of intention behaviour (= 0.687). Subjective norms, to a lesser degree, was also an important predictor of intention behaviour (= 0.593). Meanwhile, the analysis also shows that specific attitudes were indirect predictor of intention behaviour, via the mediation of subjective norms and perceived behaviour control.

Creating awareness and recognizing behavioral factors associated with recycling is essential for waste management. To identify factors influencing recycling behavior, a theory of planned behavior (TPB)-based questionnaire was designed. The aim of this study was to assess the validity and reliability of the questionnaire. This psychometric study was conducted through a multistage random sampling on 283 homemakers of Mahabad Town, Iran, in 2014. The method recommended by Ajzen and Francis was used for designing the questionnaire. Its validity was evaluated using quantitative and qualitative face validity, ration and content validity index, and qualitative judgment of an expert panel of 8 members and its structural validity using exploratory factor analysis. In addition, its reliability was assessed using internal consistency (Cronbach's alpha coefficient) and retest (intraclass correlation) methods. Of the 53 initial questions, after calculating the content validity ratio (CVR) with values higher than 0.80 and content validity index (CVI) with values higher than 0.79, we modified 3 questions and deleted 8 questions; therefore, 45 questions were approved. Using exploratory factor analysis with a varimax rotation, 9 factors with a value of higher than 1 were selected, which were able to predict 91.81% of the total variation. The reliability of the tool was confirmed through calculating Cronbach's alpha (0.87). Results of retest indicated the consistency of the questionnaire. This research found that the Persian version of the Theory of Planned Behavior Questionnaire (TPB questionnaire) has suitable validity and reliability and can be used in research and administrative activities on increasing the participation of homemakers in municipal solid waste source separation.

Malaysia is experiencing waste disposal management issues involving the lack of recycling practices among human behaviour, the absence of domestic waste recycling mechanisms, and poor enforcement for recycling activities. Previous studies revealed that households generate domestic waste hence requires changes in domestic waste management. This paper aims to establish the conceptual framework of solid waste recycling practice by employing the Theory of Planned Behaviour (TPB). Content analysis was employed to verify the trends of research in the related topic. From prior related studies, a variety of approaches based on the TPB model were examined. Results demonstrated that many factors influence the household’s behaviour in domestic waste recycling using the TPB model. The outcome of this study was a conceptual framework in determining the factors of human behaviour in domestic waste recycling. The framework can therefore be a mechanism for authority in managing domestic waste.
