Abstract:

Green environment-based initiatives and regulations are necessary, now more than ever, to protect and improve the human health and the environment for the future. In this scenario, it is imperative to design operations and production processes in accordance with the basic principles of the Green Chemistry such as: waste prevention, safer chemicals design and synthesis, renewable feedstocks use. Membranes are widely recognized, as one of the most successful cleaning technologies, in different sectors. However, despite the environmentally friendly approach adopted by membrane processes, the way the membranes are produced is not sustainable at all, often requiring the use of toxic and hazardous solvents. For this reason, the interest of the scientific research towards the use of more sustainable materials in membrane preparation is constantly increasing. Recent trends are, in fact, focused on the replacement of traditional harmful and toxic solvents, normally employed in membrane preparation, with more benign and safer alternatives (such as bio-based solvents, deep eutectic solvents and ionic liquids). A series of green solvents (e.g. Cyrene, dimethyl isosorbide, Rhodiasolv®Polarclean, ethyl lactate) have been already identified and successfully applied for the preparation of membranes employing the most common polymers. These solvents demonstrated their potentiality in producing stable membranes with defined and tailorable structures without compromising membrane properties and performance opening up new horizons for a more and more sustainable fabrication of polymeric membranes. Complementary to the use of green solvents, is the employment of sustainable materials such as biopolymers able to provide a series of undoubtable benefits including biodegradability, biocompatibility, easy processability, low cost and safe waste disposal. Seminal works have started to explore the combination of green solvents with biopolymers in order to make the entire membrane production process fully sustainable.

 

Bio:

Francesco Galiano received the degree in Pharmacy (with honours) in 2009 from the University of Calabria (Italy). He obtained his Ph.D. in “Organic Materials of Pharmaceutical Interest” at the same University in 2013. Since 2018 he has been working at the Institute on Membrane Technology of the National Research Council where he has been appointed as a permanent researcher in July 2019. In 2014, he was awarded the prize for the Best Oral Presentation at the ICOM conference and in 2021 he was selected as the winner of the Clean Technology Journal Young Investigator Award. In 2021 he was selected as a member of the Early Career Editorial Board of the Journal of Membrane Science. He serves different journals as guest editor and topic editor. Dr. Galiano has participated in several international and national scientific projects, he is the author of 69 scientific articles in international peer-reviewed journals, 2 patents and 12 book chapters. His main research activities are oriented towards the preparation, characterization and application of polymeric membranes (both in flat and hollow fiber configuration) for water treatment and purification processes. During the last years particular attention was paid on the researches aimed to the replacement of traditional toxic solvents with greener alternatives in membrane preparation.
