| Abstract Scope |
Global plastic waste crisis and underutilization of biomass demand urgent sustainable solutions. At the Eco-Friendly Center of Circular Advanced Materials & Additive Manufacturing (E-CAM), Ontario Tech University, we address this by transforming heterogeneous plastic waste—including ocean-recovered plastics and end-of-life automotive residues—and biomass fillers into eco-responsible, high-performance 3D printing feedstocks. Using high-shear melt extrusion and proprietary polymeric additives, we enhance printability, structural integrity, and processability without prior plastic sorting. Our formulations integrate biodegradable polymers, bio-based fillers, and compatibilizers to overcome degradation and incompatibility challenges. These advanced composites are targeted for construction, packaging, and automotive applications. Comprehensive rheological, mechanical, and morphological characterizations inform formulation design and guide 3D printing trials. This research supports circular economy goals by converting waste streams into low-carbon, partially or fully compostable materials that reduce reliance on virgin resources and fossil fuels. The presentation will highlight the processing strategies, material performance, and scalability potential for sustainable additive manufacturing. |
