Abstract

Reuse and recycling of construction and demolition waste (CDW) has the potential to be a major contributor to sustainable construction. Despite Nigeria's significant CDW production, the construction industry has not prioritized sustainable waste management. The aim of this research was to investigate the potential for reuse and recycling of CDW in Nigeria with specific focus on the role of informal waste workers in facilitating this. Informal waste workers play a crucial role in CDW recovery, yet formal efforts are lacking. The study employed a mixed-method approach, including surveys, interviews, and ethnography. Stakeholder perceptions were that incomplete documentation before commencing construction and material offcuts were major waste factors. Additionally, the lack of specific laws and standards for CDW management in Nigeria was highlighted. Barriers and drivers to CDW reuse and recycling in Nigeria were revealed and categorized into political, social, technical, and financial factors in figures 5.2 and 5.3. The ethnographic study details the informal CDW management process, illustrating a roadmap to the informal waste workers roles which had not previously been acknowledged in literature. The study contributes to knowledge by emphasizing the roles of informal waste workers and advocating for policy recognition and social inclusion of informal waste workers. A roadmap for recognizing the informal sector's contribution to CDW reuse and recycling is proposed as a key outcome of the study, with the potential to significantly improve CDW management practices in Nigeria.
