Sustainable Solutions for Demolished Concrete Waste in Sri Lanka: Current Practices, Challenges, and Policy Recommendations

By Sitharu Hettihewa

The construction industry is both a driver of economic growth and a major contributor to environmental challenges. Among its most pressing issues is the management of demolished concrete waste, a material that dominates construction and demolition debris worldwide. In Sri Lanka, where urbanization and infrastructure development continue to accelerate, this problem is particularly urgent. In Study on Current Practices Related to Management of Demolished Concrete Waste in Building Projects in Sri Lanka, S. S. Hettihewa investigates how the industry currently handles this critical issue. Drawing on surveys of engineers, project managers, and other professionals, the study uncovers the main causes of waste-ranging from poor planning and frequent renovations to structural failures and end-of-life demolitions. It also highlights the reliance on outdated disposal methods, such as landfilling and illegal dumping, while showing how innovative practices like recycling and reuse remain underutilized. This research does more than document shortcomings; it provides actionable pathways for change. Recommendations include adopting the 3R principles (Reduce, Reuse, Recycle), using crushed concrete as aggregates in new projects, strengthening policy frameworks, and increasing awareness through training and regulation. Comprehensive yet accessible, the book is valuable to construction professionals, policy makers, students, and sustainability advocates. It offers a rare, data-driven insight into one of the most overlooked but impactful dimensions of construction. Ultimately, Hettihewa calls for a shift from wasteful practices to sustainable solutions, demonstrating how responsible management of demolished concrete can reduce costs, conserve resources, and create a greener future for Sri Lanka's built environment.
