Construction Waste Reduction Awareness: Action Research

Abstract The study focused on construction waste reduction awareness as a step within Education for Sustainable Development (ESD) at the University of Nigeria, Nsukka. The method of collaborative action research was used with a questionnaire as an instrument. Data collected from 61 participants were analyzed using descriptive statistics (percentage, mean, and t-test) and multiple regressions. Results revealed that there were graduates of different degree levels and non-graduates working at the construction sites, where 4.9 % and 27.9 % had PhD and Master degrees, respectively. Improper material storage was agreed to be the main cause of construction waste, while the most effective reduction measure was applying source reduction through the calculated procurement. Multiple regressions revealed that awareness was significantly positively predicted by gender, qualification and status. However, both cause and reduction of construction waste were noted to be human related, thereby necessitating a campaign against construction waste at various sites, with the aim of raising motivated and inspired change agents.
