Sobre el proyecto:

In the face of escalating industrialization and its consequent pollution, the global community is increasingly invested in exploring efficient solutions for the removal of toxic pollutants from wastewater. Our research group, Biomicrosystems, has focused on exploring the use of nanocompounds based on magnetic nanoparticles as a potential solution for wastewater treatment. These nanocompounds have shown promising capabilities in remediating pollutants due to their large surface area and high reactivity. Magnetite nanoparticles (MNPs) are the most used nanoparticles in our research group for manufacturing nanocompounds. They have garnered particular attention for their cost- effectiveness, ease of manufacture, modifiability, and magnetic recoverability. However, the potential of MNPs for environmental remediation largely depends on assuring efficient synthesis methods that avoid substantial environmental impacts.

Microfluidic techniques have emerged as a promising approach for the controlled and efficient production of MNPs with improved properties. Experiments confirm that micromixers (serpentine, triangular, and 3D) effectively synthesized MNPs with homogeneous morphologies, particle size distributions, and crystalline structures. A subsequent comparative life cycle assessment (LCA) demonstrates the micromixers’ superior environmental performance compared to conventional batch co-precipitation synthesis. Additionally, this research conducts an exhaustive LCA on MNPs production at laboratory and industrial scales using micromixers. This analysis highlighted the potential of these microfluidic platforms to enable a sustainable MNPs synthesis process and their viability for large-scale production. As a result, this dissertation delves into the synthesis of MNPs with an emphasis on enhancing their efficacy and sustainability in environmental applications.

A comprehensive understanding of the sustainability performance of the synthesis methods of MNPs can be achieved by integrating environmental, economic, and exergetic analyses. Consequently, a comparative assessment is presented at an industrial scale, illuminating both the advantages and challenges of implementing micromixers for large-scale MNPs production.

In conclusion, this dissertation provides invaluable insights for industries seeking to adopt sustainable and efficient manufacturing processes for MNPs. By providing comprehensive analysis and practical recommendations, this research contributes substantially to the transition towards environmentally friendly and resource-efficient production methods.
