Safer-by-Design Green-Synthesis Nanoparticles in Environmental Engineering: A Systematic Review and Educational Framework for Risk-Informed Innovation

Presented at The "Bigger Picture" In Environmental Engineering and Sustainability- ENVIRON Division

Nanoparticles are increasingly integrated into environmental engineering and sustainable construction systems to enhance mechanical strength, durability, antimicrobial performance, and energy efficiency. However, conventional nanoparticle synthesis routes are often energy-intensive and associated with chemical hazards, raising concerns about occupational exposure, environmental release, and long-term public health impacts. In response, green synthesis methods and safer-by-design (SbD) frameworks have emerged as complementary strategies for reducing risk while maintaining functional performance. This paper presents a systematic review of peer-reviewed research papers published between 2015 and 2025 examining green-synthesized nanoparticles within environmental engineering applications, with emphasis on risk-informed innovation and engineering education. The review synthesizes evidence across four dimensions: synthesis pathways, environmental and health risk profiles, safe-and-sustainable-by-design frameworks, and curriculum integration models aligned with ISO 14001 environmental management principles. Findings indicate that green synthesis significantly reduces solvent toxicity, energy demand, and hazardous by-products compared to conventional methods, while SbD frameworks enable early-stage hazard mitigation through lifecycle thinking. Despite these advances, gaps persist in standardized life-cycle assessment, long-term toxicological data, and formal integration of nanomaterial safety into engineering curricula. To address these gaps, this paper proposes a structured educational framework that integrates SbD, green synthesis, and environmental governance into environmental engineering education, supporting responsible nanotechnology innovation.
