Implementing blockchain technology in waste management is a novel approach to environmental sustainability and accountability challenges in our modern world. Blockchain, a technology that enables decentralized and immutable ledgers, is now being re-imagined as a tool to revolutionize waste management. This innovative approach aims to improve waste management transparency, traceability, and efficiency, resulting in significant environmental and economic benefits. In traditional waste management systems, the tracking and disposal of waste materials are not transparent and can be vulnerable to fraud, mismanagement, and inefficiency. Blockchain technology provides a secure and transparent platform for recording every step in the waste management lifecycle, from waste generation to collection, transportation, recycling, or disposal. Every transaction in the blockchain is recorded in a tamper-proof manner, enabling real-time monitoring and verification of waste-related data. This paper introduces the concept of using blockchain technology in waste management. The main goal of this work is to show the implementation of blockchain technology in an existing waste management company, using smart contracts in the recycling process to provide transparency. Also, the digital product passport was redefined in terms of circular economy and waste recycling.
