Sustainability Assessment of Construction and Demolition Waste Material

Abstract

Construction and demolition waste (C&DW) constitutes a substantial portion of waste generated during construction activities, ranging from 15 to 30% globally. This waste category poses environmental threats, impacting health and the environment, particularly in Nigeria. This research investigates the environmental and economic implications of C&DW in the Nigerian construction industry, systematically addressing types, causes, and disposal methods. The study explores potential reuse through Circular Economy (CE) strategies. The literature review encompasses CE principles and Construction Waste Management in Nigeria. Employing quantitative research methods, questionnaires were administered to a selected group, revealing respondents' recognition of economic benefits from proper waste management. However, a lack of incentives and facilities for diverse disposal methods emerged as a significant challenge. Recommendations include government regulations, incentives for recycling facilities, and educational initiatives emphasizing the advantages of a circular economy. Emphasis is placed on effective information dissemination to stakeholders. This research contributes valuable insights for industry professionals, policymakers, and government entities, offering a foundation for sustainable waste management practices in the Nigerian construction sector.
