Framework for Integrating Smart Waste Management System in the South African Construction Industry.

Abstract

The construction industry in South Africa is a major contributor to solid waste generation, driven by rapid urbanization, infrastructure development, and inefficient site management. The growing volume of construction waste and the limitations of existing waste collection and disposal systems pose serious challenges for urban areas. Consequently, prior studies have emphasized the need for smart waste management (SWM) to improve waste monitoring, segregation, collection, transportation, and environmentally responsible disposal in the construction industry. Despite its potential, the adoption and performance of SWM in construction remain limited due to several persistent barriers. To address these challenges, this study proposes a comprehensive framework for enhancing SWM systems in the South African construction industry. The framework is structured around three key aspects: barriers, facilitators, and benefits of implementing SWM. A quantitative research approach was adopted using a structured questionnaire administered to construction professionals across South Africa, yielding 195 valid responses. The data were analysed using descriptive and inferential statistical techniques. The findings indicate that the primary barriers are poor digital infrastructure, high investment costs, technical complexity, and limited technical expertise. The facilitators to overcome these barriers include technological readiness, organizational capability, and institutional and regulatory support. The results further demonstrate that adopting SWM can significantly reduce landfill disposal, enhance waste reduction and material recovery, and improve operational efficiency. This study contributes to sustainable construction by providing an empirically grounded, context-specific framework to support policymakers, construction firms, and industry stakeholders in advancing innovative WM practices in South Africa and other developing countries.
