Evaluation of factors affecting efficiency of construction waste management in Vietnam

Abstract

The construction industry is developing sharply, but at the same time, it negatively affects the environment, emitting a lot of construction waste (CW). An effective management of CW brings many benefits to society, economy, and environment. Therefore, the effective management of CW has become a common aim for nations all throughout the world. Since stakeholders are the ones who directly affect the CW management (CWM), they need to clearly understand their roles and responsibilities. The study aims to identify, evaluate, and rank the factors affecting CWM in Vietnam and clarify the attitude difference on CMW between investors and contractors. Questionnaire surveys were used to collect data from people working in construction. There were 146 questionnaires for statistical analysis and 36 factors affecting CWM. The results showed that “the poor environmental awareness between the stakeholders”, “the unclear legal guidelines”, “the high recycling/recovery costs”, “the insufficient law enforcement”, and “the lack of communication between project parties throughout the project lifecycle” are considered to be the five most important factors influencing CWM. There was almost no difference in perception and opinion between the two groups including investors and contractors about the factors affecting CWM.
