Application of the Blockchain Technology in Managing Construction Waste: A Review

Construction and demolition activities generate a significant amount of construction waste, which has a negative impact on the natural environment and human health. Both academia and industry are exploring how to use information technology for efficient management. Blockchain technology, as a disruptive information technology, is increasingly valued for its unique technical features in addressing management problems. In order to gain a deeper understanding of how blockchain technology addresses the issue of construction waste management, as well as to further clarify the research hotspots and trends in this direction, this paper conducted a detailed analysis of relevant publications from 2019 to 2023, investigating the latest research in blockchain technology for managing construction waste. This was achieved through analyzing aspects such as the countries where the author was located, keyword collaboration networks, national collaboration networks, and research topics. The results of the paper indicate that blockchain technology-based management is still in its early theoretical stage and lacks practical application in specific sectors. It is worth noting that blockchain technology has real potential to improve management performance and regulatory models in multiple sectors and can provide solutions to many challenges. Therefore, based on the evaluation, we expound on the opportunities and possibilities for using blockchain technology in construction waste management.
