The rapid growth of electronic waste (e-waste) poses significant environmental and economic challenges, particularly in the efficient recovery of valuable resources. This study proposes a blockchain-enabled framework for e-waste resource recovery that utilizes smart contracts to automate and optimize metal recovery decisions. The framework performs a real-time cost-benefit analysis, evaluating economic viability based on recovery efficiency, market prices, and operational costs. To assess its feasibility, the framework was deployed on two blockchain platforms: public (e.g., Ethereum) and permissioned (e.g., Hyperledger Fabric). Smart contracts are used to process e-waste batches, integrate external price feeds, and determine net recovery gains. A detailed performance test demonstrates that Hyperledger Fabric beats Ethereum in terms of execution speed, scalability, and cost efficiency, making it perfect for enterprise-level circular economy applications. Ethereum can, however, surpass Hyperledger Fabric in terms of simple setup and public accessibility, making it suitable for open stakeholder systems. This study demonstrates how blockchain technology may improve transparency, automation, and economic efficiency in e-waste management, resulting in sustainable resource recovery and contribution to the circular economy.
