Ritesh Sharma, a FinnCERES funded PhD student at Aalto University, is exploring functionalized cellulose fibers using bio-based substances. In the initial phase of his doctoral project, Ritesh is investigating the potential of bio-based substances, particularly natural dye extracts, to enhance the functionality of cellulosic fibers.
He has studied Chokeberry (Aronia) for its potent, non-toxic dyeing properties. This research is vital as it addresses the fact that 99% of all dyes currently used are derived from petroleum. By pushing for the usage of natural alternatives, Ritesh hopes to provide not just long-term remedies but also additional benefits such as antimicrobial properties to the cellulosic fibers.
Looking ahead to the second year of his research, Ritesh plans to investigate the Hydrophobization of cellulosic fibers utilizing bio-based compounds, expanding the eco-friendly concept. Reflecting on his journey, Ritesh emphasizes, "Sustainability has remained a guiding principle throughout my academic pursuit. Aalto University has provided an excellent opportunity to pursue my passion for eco-friendly solutions.”
