Enhancing Transparency and Efficiency: Leveraging Blockchain for Overcoming Challenges in Plastic Recycling Industry

The effective management of physical flows and information is a major challenge for PET plastic recycling companies. In this study, we propose a decision-making modeling approach to ensure traceability and reliability of data throughout the supply chain. Our system, using robust processes and appropriate technological infrastructure, allows for the collection, verification, and exchange of information related to PET plastic waste between various stakeholders. Using a combination of quantitative and qualitative techniques, we provide in-depth analysis of data to optimize business operations and avoid discrepancies between the quantities of waste delivered by suppliers and the quantities sold. Our study results demonstrate the effectiveness of our approach in controlling flows and ensuring data reliability, contributing to a more sustainable and responsible supply chain management in the PET plastic recycling industry.
