Excessive production, consumption, and indiscriminate disposal of plastic waste contribute to plastic pollution, which has a negative impact on the environment and human health. The KAP (knowledge, attitude, and practices) study is thought to be useful in mitigating plastic pollution because understanding the public’s knowledge, attitude, and practices toward plastic pollution can help identify problems and challenges, allowing appropriate policy decisions to be made to set up plans or implement interventions. This study assesses Malaysians’ level of knowledge, attitude, and practices toward plastic pollution, as well as the variation of plastic pollution related to KAP among various socio-demographic groups. For this study, an online survey received 294 valid responses. Descriptive statistics, KAP scoring, and response cross-tabulation were calculated. This study received 294 valid responses via an online survey. Descriptive statistics, KAP scoring, and response cross-tabulation were estimated. A one-way analysis of variance, paired t-test, and binary logistic regressions was performed. Respondents’ overall knowledge score (95% CI mean score: 3.88–10.94 on a scale of 11) and practice score (95% CI 1.09–6.53 on a scale of 6) were poor across socio-demographics when a cut point of 80% was used. Older (>46 years) respondents seemed to have more knowledge than younger (18–30 years) respondents (odds ratio, OR 4.304; p < 0.01). However, respondents between the ages of 31 and 45 reported significantly (p < 0.01) higher attitudes (OR 4.019) and practices (OR 4.056; p < 0.05). Respondents with environmental-related university education had a higher likelihood of knowing about plastic pollution (OR 10.343; p < 0.01). To encourage good practices toward minimizing plastic use and pollution, conclusions are drawn about undertaking interventions such as raising environmental awareness, incorporating plastic pollution topics into formal and informal education, and providing recycling facilities in nearby communities.
