Innovative Waste Management Through the Use of Waste Management Plans on Construction Projects in Nigeria

Abstract The complexity and dynamism of construction projects require innovative approaches to ensure stakeholders' satisfaction. Construction waste management is no doubt a sine qua non to sustainability and needs innovation to ensure waste minimization. The application of a waste management plan (WMP) in previous projects has shown that it can lead to waste minimization. A survey was therefore conducted using a convenience-sampling technique to explore the application and effects of a WMP on construction projects in Nigeria. The population of the study comprised construction professionals in construction companies in Lagos State, Nigeria. A questionnaire was created to gather information for the study. Descriptive and inferential statistical tools were used for the analysis. The findings revealed that WMPs are applied ‘averagely’ in Nigerian construction projects: the effects of a WMP on materials, labour and time waste minimization are mostly average, whereas it is high on equipment waste minimization; the most important effect of a WMP is on materials waste. The majority of the construction companies consider the use of a WMP at the tender stage whereas only a few of them consider it at the pretender stage. The study recommends inter alia that practitioners should be cognizant of the use of WMPs to minimize all categories of waste, especially materials, on their projects.
