Industrial waste, fragile supply chains and decarbonization targets rarely arrive one at a time. In a macroeconomic supply chain, choices made today inside one industry can cascade across suppliers, recyclers and regulators tomorrow. Traditional tools often treat these pieces in isolation, leaving decision makers without a unified view of how to design for true circularity. This fragmentation obscures feedback, delays investment and dulls accountability across value chains. Abhimanyu Raj Shekhar, a Bilsland Fellow and fifth-year PhD candidate in Purdue’s Department of Agricultural & Biological Engineering, is tackling those challenges together.
