Abstract
The rapid increase in volume and types of hazardous waste (HW) due to China's continuous economic growth makes it significant to conduct HW safety management. However, due to the information asymmetry between the regulators and regulated institutions, problems such as illegal dumping and statistical fraud are common in hazardous waste transfer (HWT) activities. Moreover, there is a severe problem of information isolated island among waste production, transportation, and treatment companies in the HW market. Promoting the information monitoring and tracking of the whole process of HWT is the main challenge for HW management. Blockchain provides an ideal solution to overcome the above challenges. This study developed a framework for the blockchain-based HWT management system, which could support government regulators to obtain relevant information in HWT and improve the efficiency of HWT. The HWT management system was introduced in detail from different perspectives, including infrastructure, blockchain service, functions, and users, emphasizing six information management functions. Finally, the positive impact and various challenges encountered in implementing blockchain in HWT management were discussed. This study applies blockchain to the research field of HWT management, which expands the application of blockchain in the field of solid waste management with great theoretical and practical significance.
Highlights
With China's rapid development, hazardous waste (HW)'s generation is increasing rapidly (Wang et al, 2017)

The root of the HW problem lies in the severe information asymmetry among enterprises and governments, which leads to significant uncertainty in the process of hazardous waste management (CNRRA, 2016)
Summary
With China's rapid development, HW's generation is increasing rapidly (Wang et al, 2017). Due to information management's imperfection and the lack of adequate supervision, more and more HW-related criminal cases occurred during HWT processes. It is urgent to apply emerging technologies to improve the HWT process's supervision, reduce the information asymmetry between the company and the government, and combat illegal behaviors. HW production company, weight, collection time, disposal time, treatment company,and other data are collected and counted by information technology, which can timely and accurately grasp the waste disposal situation and improve the management level. HW's legal out-of-warehouse volume will be supervised using smart electronic scales, camera networking, and other equipment It will be difficult for the environmental protection department to control the daily waste production by relying on the enterprise account. The last section summarizes the full text and points out the future research direction
