Assessment of the Contractor Perceptions on Adoption of the 3r Concept of Construction Waste Management on Kampala Building Projects

Abstract

Construction waste management is a critical aspect of sustainable development, and the successful adoption of the 3R concept—Reduce, Reuse, recycle—is paramount in mitigating environmental impact. This research explored the pivotal role contractors play in the successful implementation of the 3R concept in construction waste management. The study sought to understand the factors that contribute to contractors' willingness or resistance to embracing the 3R concept. This is because it is crucial for tailoring interventions and strategies that align with their needs Through a mixed-methods approach, including surveys and thematic analyses of open-ended responses, data was collected from 55 contractors operating in Kampala, Uganda. The findings revealed a variety of perceptions, barriers, and perceived benefits associated with 3R adoption. While many contractors expressed enthusiasm and willingness to embrace sustainable practices, barriers such as limited awareness, cost implications, and regulatory constraints hindered adoption efforts. Nevertheless, contractors recognized several benefits, including cost savings, environmental sustainability, and improved project management, associated with 3R implementation. The study concludes with recommendations for overcoming barriers and fostering successful adoption, including investing in education and awareness initiatives, improving recycling infrastructure, and integrating 3R principles into project management practices.
