Advancing Sustainable 3D Printing: Harnessing the Potential of Wastewater Sludge Incineration Ash for Composite Material Development and Practical Applications

Abstract

This study delves into the unexplored fusion of wastewater sludge incineration ash (WSIA) and 3D printing, uncovering novel possibilities at the crossroads of environmental engineering and advanced manufacturing. The investigation centers on the integration of WSIA within the additive manufacturing framework, specifically material extrusion-fused deposition modeling (FDM). The study focuses on composite materials blending WSIA with commercial thermoplastics like ABS and PC, meticulously analyzing their physical, chemical, and mechanical attributes. Notably, the research highlights the potential for heightened mechanical strength in ABS composite materials, suggesting applications beyond 3D printing. Emphasizing long-term sustainability, the study advocates for the adoption of biodegradable plastics and underscores the importance of continuous research, mass production feasibility, and regulatory adaptations to fully unlock WSIA’s potential. This synergy of innovation marries environmental awareness with technological progress, offering a harmonious trajectory to reshape manufacturing paradigms and nurture sustainable development. The study’s outcomes present promising avenues for redefining the construction industry and advancing environmental conservation.
