Plastic waste knowledge of households towards a sustainable environment

Abstract

Plastic waste in Malaysia has become a serious problem since it affects not only the environment but wildlife animals and marine life too. These may cause by irresponsible people in dealing with their plastic waste management. Therefore, this study is conducted mainly to analyse the knowledge, attitude, awareness, and behaviours of households in Pasir Gudang towards plastic waste management in separating plastic waste before its disposal. A questionnaire was distributed among households who live in this area. The Binary Logistic Regression is used to analyse the knowledge, attitude, awareness, and behaviour of households towards plastic waste management. The results show that only the behaviours of households affect the plastic waste management in their households (p-value=0.04). The Hosmer-Lemeshow test indicates the model has a good fit for the data (p-value=0.480). Other than that, the Omnibus test (p-value=0.03) shows predictors have significant effects and gave improvement to the model. The Classification Table shows the accuracy of 67.4% of the households who separated plastic waste before its disposal. It is suggested to improve the result by adding more respondents to provide insight information on the independent variables, analyse further using other approach such as decision tree and parallelly acknowledge others on the importance of recycling plastic waste.
