This is a case study in behavioural patterns and psychological analysis in Plastic-waste segregation in the capital city of Nepal, Kathmandu Valley. This paper is majorly based on a TPB survey conducted in Kathmandu Valley and then the data collected is analysed through SmartPLS 3.0. TPB is used considerably in behaviour narrative and social sciences. Main objective of this research is to ascertain the impact of Plastic-waste Segregation Intention and Situational Factors on Plastic-waste Segregation Behaviour on residents of Kathmandu Valley. The tributary purposes are to investigate the pertinency of Theory of Planned Behaviour in envisaging and illuminating Plastic-waste Segregation Behaviours in Nepal, and to postulate explanation representing the relevance of SEM by using SmartPLS. This research altered and prolonged the benchmark Theory of Planned Behaviour model and created a hypothetical with the inclusion of Plastic-waste Knowledge, Morality and Situational Factors. Understanding these factors that affect resident{u2019}s waste Segregation behaviours can massively help in developing operative eco-friendly operations for the society or in this research{u2019}s perspective Kathmandu Valley. Data drawn from 252 E-Mail Surveys, precisely Google Forms, were utilised to evaluate socio-demographic considerations. The Mail Survey data revealed that Plastic-waste Knowledge and Morality had significant positive effects on Attitude regarding Plastic-waste Segregation whereas Conditional Factors had noteworthy positive effects on Plastic-waste Segregation Behaviour in Kathmandu Valley. The result from this research also demonstrated that Plastic-waste Segregation Behaviour in Kathmandu Valley is hugely dependent on Situational Factors towards Plastic-waste Segregation rather than Plastic-waste Segregation Intention of the residents. Through SEM analysis, it can be concluded that the regulations for Plastic-waste Management may particularly be operative in growing the involvement ratio in Plastic-waste Segregation Behaviour.
