ABSTRACT
Medical waste management is a challenging problem that not only directly affects the environment but also people's health. This urgent issue is getting more and more attention in the context of the Covid-19 pandemic. New infections are increasing exponentially in all countries globally, especially developing countries with large populations (e.g., India, Brazil, Bangladesh). Studies on the spread of the disease have listed one of the causes of this crisis as the Covid-19 waste treatment process not being followed correctly and the difficulty of data retrieval. Vietnam was also severely damaged by the Covid-19 epidemic, although the government initially controlled the disease very well. The Covid-19 waste treatment process in Vietnam is still being processed manually and with a combination of many departments. Data sharing and tracking are also tricky because they are centrally stored in different facilities/departments. In addition, there is a lack of synchronization and transparency of shared data. This paper is one of the first attempts to fill that gaps by applying Blockchain technology and decentralized storage. Relevant parties will retrieve all data, and the source of waste can be easily traced. We also implemented a proof-of-concept based on the Hyperledger Fabric platform to demonstrate the idea's feasibility. In the evaluation, we observe the process of initializing and querying data. These initial efforts will lay the groundwork for more in-depth studies to create an initiative for Vietnam's medical waste treatment process when faced with a new wave of infections or another epidemic. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
