Abstract: The construction sector contributes significantly to waste generation and resource depletion. Identifying potential household waste for reuse and recycling as secondary raw materials has emerged as a key technique for addressing these environmental concerns. This study uses the Colombo municipality in Sri Lanka to identify and evaluate household waste products having the potential to be reused as secondary raw materials in the construction sector. The study employs a mixed method for data collection and analysis. First, a questionnaire survey of industry experts was conducted to identify and assess the requirements for household waste that may be utilized in the construction sector, followed by a complete literature analysis to determine the reuse applications of potential household waste. The findings of this study will be useful in identifying and evaluating household waste items that may be recycled as secondary raw materials in the construction sector. It would also help to establish sustainable waste management techniques and circular economy practices in Sri Lanka. The study’s findings can help policymakers, waste management authorities, and stakeholders in the construction industry to implement effective waste management practices and promote the use of recycled materials in construction projects, reducing environmental impact and conserving natural resources.
