Current construction and demolition waste management strategies for Philippine construction sector – A systematic literature review

Abstract

The construction industry continues to be one of the primary drivers of a country's economic progress. As of 2022, the Philippines’ construction sector had an annual growth rate of 9.2% and continues to increase due to the Build! Build! Build! (BBB) program. However, the construction sector is globally known for regularly consuming more raw materials, resulting in natural resource scarcity and environmental implications. Construction activities also generated a massive volume of construction waste from construction, demolition, and renovation. The need to impose construction and demolition waste (CDW) management strategies and policies in all stages of construction is crucial in attaining a more sustainable construction. This study aims to explore the current CDW management practices and policies from existing literature. The findings of this research will present many potential strategies and solutions that the Philippines can adopt to create more sustainable construction while also assisting in combating environmental issues and concerns in attaining sustainable construction. The study will utilize a Systematic Literature Review (SLR) to identify relevant studies in CDW management to gain the best practices and current trends in CDW management. The study's findings show that at least 26 strategies have been implemented in the construction industry. These can be grouped into 6 major groups: information technology, policy, design, operations, knowledge, and procurement based.
