In Malaysia, construction waste generation increases annually, with the majority of construction waste ending up in illegal dumping sites. Indeed, construction waste can be effectively recycled if it is segregated. Waste segregation is currently enforced and mandatory in Malaysia's states that have enacted the Solid Waste and Public Cleansing Management Act 2007 (Act 672). However, construction companies are not required to practise sustainable waste management practices such as waste segregation. In Malaysia, there has been no widely published research describing the practice of on-site waste segregation. The research aims to identify the approaches to on-site waste segregation that have been implemented and the factors that influence their implementation. The data collection method used was a case study of the MRT police quarter project in Gombak, where a literature review, site survey, and interviews were conducted. It was discovered that waste segregation had become a more integral part of routine construction activities in Malaysia. Disruption to normal site activities, management effort, and project stakeholders' attitudes are the most critical factors. In contrast, cost, sitespace, environmental confinement, and facility demand are no longer identified as factors to consider when implementing on-site segregation. Rather than that, education is now viewed as a new potential factor in these practices. The study's findings can be used to assess the state-of-the-art and effectiveness of current on-site segregation in Malaysia and develop benchmarking strategies and best practices for on-site segregation.
