ABSTRACT

The circular economy has the potential to increase resource efficiency and minimize waste through the 4R framework of reducing, reusing, recycling, and recovering. Blockchain technology is currently considered a valuable aid in the transition to a circular economy. Its decentralized and tamper-resistant nature enables the construction of transparent and secure supply chain management systems, thereby improving product accountability and traceability. However, the full potential of blockchain technology in circular economy models will not be realized until a number of concerns, including scalability, interoperability, data protection, and regulatory and legal issues, are addressed. More research and stakeholder participation are required to overcome these limitations and achieve the benefits of blockchain technology in promoting a circular economy. This article presents a systematic literature review (SLR) that identified industry use cases for blockchain-driven circular economy models and offered architectures to minimize resource consumption, prices, and inefficiencies while encouraging the reuse, recycling, and recovery of end-of-life products. Three main outcomes emerged from our review of 41 documents, which included scholarly publications, Twitter-linked information, and Google results. The relationship between blockchain and the 4R framework for circular economy; discussion the terminology and various forms of blockchain and circular economy; and identification of the challenges and obstacles that blockchain technology may face in enabling a circular economy. This research shows how blockchain technology can help with the transition to a circular economy. Yet, it emphasizes the importance of additional study and stakeholder participation to overcome potential hurdles and obstacles in implementing blockchain-driven circular economy models.

研究动机与目标

• 评估区块链在循环经济转型中如何促进4R中的每一项（Reduce、Reuse、Recycle、Recover）。
• 识别将区块链应用于循环经济模型的行业用例与架构。
• 综合将区块链应用于循环经济倡议的主要挑战与局限性。
• 评估基于区块链的循环经济解决方案与R框架（3R、4R、6R、9R）及行业实践的一致性。
• 突出研究空白和利益相关者考虑，以推动区块链驱动的循环经济发展。

提出的方法

• 按照PRISMA指南进行系统性文献综述（SLR）。
• 使用与区块链、循环经济和4R/R框架相关的关键词检索七个数据库。
• 基于纳入/排除标准和质量评估问题（QAQs）筛选并选择研究。
• 将选定的研究分类为Reduce、Reuse、Recycle、Recover和其他类别以供分析。
• 综合发现，将区块链驱动的循环经济解决方案映射到4R框架并识别挑战。
