Assessing The Relevance Of Waste Management System In The Construction Industry In Warri

Abstract

This study assesses the relevance and implementation of waste management systems in the construction industry, using Warri, Delta State, as a case study. Employing a mixed-methods approach, the study draws data from 41 survey respondents and in-depth interviews with 7 industry professionals to analyze the types, sources, and impacts of construction waste, as well as current waste management practices. The research reveals that construction sites in Warri commonly generate waste from cement packaging, timber formwork, demolition, and poor material handling. While over 63% of respondents claimed to have waste management plans, the actual implementation varied significantly, with only 39.5% consistently sorting waste on-site. Qualitative insights further indicated that labour inefficiencies, lack of training, poor supervision, and inadequate regulation remain core barriers to effective waste reduction. The study also found that unmanaged waste contributes to site congestion, project delays, safety hazards, and increased costs, despite many professionals underestimating its impact. Policy enforcement by regulatory bodies was seen as inconsistent, with participants advocating for stricter monitoring, better training, and improved access to recycling infrastructure. The findings underscore the need for an integrated strategy combining government regulation, contractor compliance, professional oversight, and worker education to improve waste management outcomes in Warri.
