“Design of Silica-Based Materials from Industrial Waste”
 involves the valorization of Hexafluorosilicic Acid (HFA) from industrial waste by processing it into high-purity silica having chemical-physical properties which make it suitable for use as a reinforcing agent for rubber tyres or as a matrix for the production of sorbents and catalysts. The research aims to create technological and process know-how that enables the valorization of HFA-containing wastewater, currently generated by various industrial processes, in order to develop new high value-added silica-based materials, rationalize the wastewater treatment system and reduce the production of industrial waste.

Financial Resources
This research project was funded by the NOP Research and Innovation 2014-2020 under the action “Innovative Industrial Doctorates”, cycle XXXII (Academic Year 2016-2017). For the implementation of this initiative, the University of Cagliari, which received 83.462,96 euro in funding, has instituted a three-year doctoral scholarship at the Department of Chemical Sciences and Technologies. 

The project falls within the thematic area “Green Chemistry” and is in line with the National Smart Specialization Strategy since it involves the exploitation of research results through the synergy between basic and applied research, which in this case will translate into the transformation of an industrial waste product into one or more commercial products, with a consequent decrease in the production of solid sewage sludge of low commercial value. The project includes a 12-month period at Fluorsid S.p.A, a chemical company based in Assemini (Cagliari), and a 6-month period at Charles University in Prague. The synthesis of silica will be carried out at the two laboratories of the company and the University of Cagliari. The innovative technological solutions that will be identified may bring economic benefits to the company thanks to the rationalization of wastewater treatment systems, the reduction of waste and the introduction of new products leading to revenue increase and diversification.
