Sanna Hellsten serves as Coordinator in the Department of Bioproducts and Biosystems and Bioproduct Chemistry at Aalto University. She is actively involved in research related to cellulose fiber production, ionic liquids, and sustainable textile manufacturing processes, contributing to UN Sustainable Development Goals.
Her educational background includes:
- Doctoral degree in Engineering and Technology from LUT University (awarded December 31, 2013)
- Master's degree in Engineering and Technology from LUT University (awarded December 19, 2008)
- Bachelor's degree in Engineering and Technology from LUT University (awarded June 18, 2008)
Sanna Hellsten's research focuses on sustainable bioproduct development, particularly in the area of cellulose-based materials and textile manufacturing. Her work centers on the Lyocell process using ionic liquids as solvents for cellulose dissolution and fiber spinning. She investigates solvent recycling methods, process limitations, and analytical techniques like Raman spectroscopy for process monitoring. Her research contributes to circular economy approaches in the textile industry, aiming to develop more sustainable methods for producing regenerated cellulose fibers from waste materials like old textiles and paper.
Her recent publications demonstrate expertise in ionic liquid chemistry, cellulose processing, and analytical methods for industrial applications. She has made significant contributions to understanding the limitations and potential of superbase-based ionic liquids in the Lyocell process, with research showing how dissolving pulp can be adapted as a solution for sustainable textile production.
Sanna Hellsten has received recognition for her work:
- DIA Design Intelligence Award, China (2018)
Sanna Hellsten is actively involved in multiple research projects including FinnCERES (Competence Center for the Materials Bioeconomy: A Flagship for our Sustainable Future, 2022-2026), SolvRec (Technical development of Ioncell-F with special emphasis on solvent recycling, 2017-2019), and TeKiDe (Textile fiber recycling demonstration platform). She collaborates extensively with researchers from various institutions and has presented her work internationally, including at conferences on ionic liquid recycling in cellulose fiber spinning. Her research has practical applications in developing more sustainable textile manufacturing processes that could help Finland capture a significant share of the global sustainable textile market.
She is part of the research team working on the Ioncell technology, which aims to revolutionize textile production by creating high-quality fibers from recycled materials using environmentally friendly processes. This work has attracted media attention in Finland and internationally, with statements highlighting how 'Finland could capture a third of the billion-dollar market' in sustainable textiles.
