Abstract
While Blockchain Technology (BCT) is widely touted as an enabler for the Circular Economy (CE), engineering managers lack structured tools to evaluate which technical features align with specific circular strategies. This article presents a practical decision-support framework using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Integrating the Technology-Organization-Environment (TOE) framework with the Technology Acceptance Model (TAM), we prioritize BCT characteristics such as immutability, transparency, and smart contracts across six key circular practices. Results from a panel of domain experts indicate that while transparency is universally critical, specific features like cryptography are nonnegotiable for Digital Product Passports (DPP) but less relevant for material recovery. Furthermore, sensitivity analysis reveals that deploying blockchain as a Decision Support System offers higher organizational utility than purely financial use cases. This study provides a quantifiable roadmap for technology leaders to de-risk blockchain adoption in sustainable supply chains.
