Description
This study focuses on the practice of waste management in the construction industry in Nigeria, using a case study of Cakasa Nigeria Company during the construction of a tank farm from 2019 2022. The study analyzed waste data from consignment notes and found that metal waste (4370kg) was the most generated waste material on site, followed by concrete and bricks (3973 kg), timber (2850kg), masonry and plasterboard (2595 kg), and paper waste (1621 kg). Oil rags (16 kg) were the least generated waste. The factors influencing material waste production during construction were identified as design changes, theft and vandalism, poor site conditions, poor waste minimization strategy, poor procurement management, poor materials handling on site, and poor implementation of waste management plan. Measures to minimize construction material waste included proper site supervision and management techniques, adequate material storage, staff training and awareness, and proper procurement management.
