Assessment of Construction Sites Sustainable Waste Management Strategies in Abuja

Abstract

Waste management and sustainability are two fundamental underlying ideas that the construction industry must recognise and execute. Nevertheless, doing so may be difficult and time-consuming. To this end, the aim of this study is to assess sustainable waste management strategies adopted at construction sites in Abuja with the view to enhancing material waste sustainability practises adopted by construction firms on construction sites. The study adopted a quantitative research approach with the use of a structured questionnaire, administered to 155 respondents. Of the 155 questionnaire copies administered, 150 copies were returned and used for data analysis, giving a response rate of 97%. The analysis of the data was carried out with the use of percentage, mean item score (MIS), and factor analysis. The study identified six (6) factors affecting the management of material waste on construction sites, of which financial factors (MIS = 4.08) are the most significant factors. Material costs and energy costs were the most important social sustainability factors (MS = 3.80 and 3.80) respectively. Reimagine and re-design were identified as the most significant strategies (MS = 4.50). The recycling strategy was identified as the most effective strategy (MS = 4.70). The KMO value is 0.655, and the Bartlett’s test of sphericity is significant (p < 0.05). However, it is, therefore, that the adoption of a sustainable building construction waste management process will minimise, reuse, and recycle construction waste to the greatest extent possible to alleviate the construction waste issue in Abuja and Nigeria at large. The major recommendation from the study was that for waste management to be sustainable in the Nigerian construction sector,
