The assessment of waste segregation exercise among Malaysian contractors: a descriptive analysis

Construction waste that emerges from construction sites has become a major global concern due to its negative carbon footprint on the environment. Due to underrepresented construction waste specific data in Malaysia, this paper aims to identify sources, causes, types of construction waste and decisi...
