An implementation framework of blockchain-based hazardous waste transfer management system

The rapid increase in volume and types of hazardous waste (HW) due to China's rapid economic development makes it significant to conduct HW safety management. However, due to the information asymmetry between the regularors 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 companies, transportation companies, and treatment companies in the HW market. Promoting the monitoring and information traceability 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 builds a framework of the blockchain-based HWT management system, enabling government regulators to obtain relevant information in HWT and improve HW's convenience. The system is introduced in detail from the 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.
