Comparison of legislation of UK and Sri Lanka for better implementation of circular economy in Sri Lankan construction industry

The construction industry (CI)is a significant contributor to worldwide environmental pollution while being a substantial user of finite resources and a substantial generator of waste. The Circular Economy (CE) concept aims to manage raw materials and minimise waste generation. The lack of relevant laws and regulations is a significant barrier to the implementation of CE. It is necessary to have a systematic approach to design and implement CE laws to cover the multi-sector dimensions of the CE concept. Limited research is available on laws and regulations related to the CE in the global and Sri Lankan contexts. This study aims to compare the legislation provisions for CE in CI in Sri Lanka and the United Kingdom (UK) for the better implementation of CE in CI in Sri Lanka. The study investigates how CE principles can be integrated into construction strategies in Sri Lanka, drawing from existing legal frameworks in the UK, and conducted through a review of legislation and policies. Findings reveal that the UK has made significant progress in embedding CE principles through legislative support and sustainable construction regulations. However, Sri Lanka is still in the early stages of this transition. This study further identified legal pitfalls in integrating CE practices, including gaps in the enforcement of CE within the Sri Lankan CI. The study concludes with key recommendations for introducing laws, legally supported CE practices in Sri Lanka, CE new legal reforms, and incorporation of CE principles into construction law.
