Many people are now expressing their increased concern about serious environmental destruction as a result of human irresponsible environmental behaviour. The aim of this paper is to explore current scenarios of intention to practise solid waste segregation-at-source between households in Selangor. A total of 400 respondents in Selangor who aged 18 and above were employed to respond to bilingual research questionnaires. The results of the descriptive investigation indicated that plastic was the most major solid waste material segregated daily among the respondents. The majority of Selangor citizens surveyed had heard about and strongly supported this environmental policy. Approximately half of the sample agreed that the policy of solid waste segregation-at-source was extremely important in addressing serious negative global environmental issues. Unfortunately, due to a lack of awareness as well as insufficient technologies and facilities in their housing areas, one-fifth of the respondents had never intended to practise solid waste segregation-at-source in their daily lives. By realising ongoing challenges in the long-term implementation of solid waste segregation-at-source in Malaysia, this current research therefore provides an essential opportunity to explore the importance of having the intention to practise solid waste segregation-at-source among Malaysian citizens and of enriching existing local literature.
