Blockchain application in circular marine plastic debris management

Abstract

The threat to the environment and humanity caused by marine plastic debris has aroused global attention. This research aims to explore the feasibility of applying blockchain technology (BCT) in marine plastic debris management. A case study on three pioneer recycling organizations is conducted based on secondary data. The study found that BCT can be applied to solve some of the existing challenges of marine plastic debris management. A digital token system and identity recognition mechanism based on BCT can increase the public awareness for marine plastic debris governance. The derived digital wallets and distributed ledgers can effectively replace paper documents and cash transactions in the traditional recycling chain, and minimize global impact on local economies, thus improve efficiency and safety. Also, the traceability and high transparency of blockchain and the application of smart contracts can effectively build a global recycling network. In addition, the application of BCT can greatly improve the transparency of recycling value chains, and make them more accepting of supervision from society and consumers. This research is one of the first studies on BCT in marine plastic debris management and explores worldwide pioneering companies. In practice, this study can help companies analyse the defects in their own waste disposal models and help practitioners make decisions to adopt BCT. In academia, as one of the early exploratory studies on the application of BCT to the treatment of marine plastic debris, this study provides further empirical reference on BCT based business models and recycling chains, and can guide future research in this field.
