Our research areas:
- Added value materials from biocolloids (e.g., foams, hydrogels, composites)
- Sustainable surface functionalization of cellulosics (e.g., textiles, barrier materials)
- Side-stream valorization (e.g., lignin, waxes, extracts)
FinnCERES - Flagship for boosting bioeconomy
Boosting the world’s bioeconomy by developing new bio-based materials with Aalto University and VTT, companies, and research organizations through a shared passion to create a sustainable future and a belief in innovations based on solid scientific foundations.
Added-value materials from biocolloids
Aiming for more sustainable use of natural resources, we work on the development of new value-added materials based on cellulose nanofibrils, hemicelluloses, and colloidal lignin particles to replace fossil-oil-based materials in areas ranging from packaging and coatings to tissue engineering.
Sustainable surface functionalization of cellulosics
We explore different green approaches for surface modification. Nontoxic approaches for protective coating solutions with controlled breathability for surfaces like wood and textiles are explored. We investigate fundamental understanding of the surface interactions and film formation for the development of bio-based barrier materials.
Surface functionalization projects
An important part of our research is devoted to the transformation of waste lignin from biorefineries and pulp industries into high-added-value products. The preparation, modification and utilization of lignin nanoparticles are at the core of this research line. Bio-based coatings, adhesives, and composites are some examples of commercial applications of colloidal lignin particles we are working on.
Components from bark extracts are also studied as biocolorants and for packaging, and other added-value applications. One project is to develop bio-based dyes and pigments to replace synthetic dyes commonly used in the textile industry.
