Evaluation of Materials Waste Reuse Methods on Construction Sites in Ibadan Metropolis, Nigeria

Abstract

The construction industry is affected by the continuous generation of waste and poor waste management. Thus, waste management has become a major concern in the industry, as waste cannot be eliminated due to off-cuts of materials from the irregular shape, change in design during construction cause diverse waste. This study, therefore, assesses material that is prone to waste and identifies methods of reuse on construction sites. A pilot survey on registered building construction firms in which head-offices are located within the Ibadan metropolis was conducted based on the list of top construction companies obtained from the Bureau of Public Procurement in Oyo State, Nigeria. “Five” construction firms confirmed they practice waste management and shared their experience on worksites. A qualitative research approach was used to evaluate the objectives of the study. Content analysis and frequency were used as the basic analytical tool of the study. Results show that repurpose, remanufacture and salvage methods are proactive reuse methods to achieve low waste generated on construction sites. The study concluded that the use of reusable construction materials waste on construction sites will promote quality materials usage and save time taken to purchase new materials.
