Technology Description:

Municipal solid waste (MSW) management involves three primary practices: landfilling, recycling, and incineration for energy recovery (waste-to-energy or WTE). WTE is a potentially sustainable method of MSW management because it reduces landfilling and generates energy. Incineration reduces input waste mass by 70%. The remaining 30%—in the form of bottom and fly ashes—has to be discarded or landfilled. A main barrier to beneficial use of these ashes is the variability in their composition, which renders them as an unreliable byproduct. The University of Illinois aims to design a low-cost and rapid real-time AI-based ash analysis technology that accurately predicts ash composition and its performance as a potential byproduct.
