随着全球对释放到环境中的报废（EoL）废物的关注日益增加，提高回收系统透明度的需求也越来越大。为了解决废物可追溯性问题，区块链等技术可以帮助妥善处置和处理废物。在本文中，我们提出了一种基于区块链的固体废物管理（SWM）模型，可以帮助市政当局提高废物管理工作的效率。提出了一个由市政当局拥有和控制的区块链框架，在该框架中，客户公司付费加入该平台，以利用市政当局管理的供应商提供的服务。对供应商和消费者公司的成本负担进行了讨论。此外，开发了一个优化模型，以确定最佳数量的废物，可以在供应商和消费者公司之间进行交易，以最大限度地提高他们的利润的基础上的参数，如供应商，消费者公司的数量和客户公司的处理能力和几个约束条件，包括最大存储容量，存储和运输的限制。此外，与区块链实施相关的成本方面是从提供区块链解决方案的公司获得的几个用例中估计的。
As global concerns over End-of-Life (EoL) wastes released to the environment is rising, the need for enhancing the transparency of recycling systems is growing. To address the waste traceability issue, technologies such as Blockchain can be instrumental in the proper disposal and handling of wastes. In this paper, we propose a Blockchain-based Solid Waste Management (SWM) model that can help municipalities enhance the efficiency of their waste management efforts. A Blockchain framework owned and controlled by a municipality is proposed in which customer companies pay to join the platform to avail services from the suppliers managed by the municipality. The cost burdens to both supplier and consumer companies have been discussed. In addition, an optimization model is developed to determine the optimal quantity of waste that can be traded between supplier and consumer companies in order to maximize their profit based on parameters such as the number of suppliers, consumer companies, and the processing capacity of customer companies and several constraints including maximum storing capacity, storage, and transportation constraints. Further, the cost aspects associated with Blockchain implementation are estimated from several use cases obtained from companies providing Blockchain solutions.
