Sustainable Production of Magnetite Nanoparticles: Environmental and Economic Benefits

What is it about?

The research conducted a comprehensive evaluation of large-scale magnetite nanoparticle (MNP) production processes, focusing on environmental, economic, and exergy aspects. It assessed four case studies to determine the sustainability of different production methods, with a particular emphasis on the use of microfluidic devices. The environmental assessment, using life cycle assessment, identified that Case Study 4, which utilized microfluidic devices, had the most favorable environmental footprint, with the lowest electricity impact. Economically, Case Study 4 was found to be the most viable, with a high net present value and benefit-cost ratio, indicating strong financial feasibility. The exergetic analysis showed that Case Study 4 also had the least total exergy destruction, highlighting its superior thermodynamic efficiency. Overall, the study provided insights into improving the sustainability of MNP production by adopting microfluidic technology, which enhances environmental performance, economic feasibility, and energy utilization.
