Better Nanocellulose with Forest Side Streams!

Video - Published 7.8.2023

Researchers at FinnCERES, Aalto University, and VTT have developed an additive derived from tree bark to enhance the properties of nanocellulose without the use of fossil-based additives.

Nanocellulose has the inherent ability to bind a significant amount of water, making it useful in various applications, from wound dressings to packaging. However, its dry form poses challenges. The researchers have found a solution by utilizing a bio-degradable additive derived from tree bark.

The phenolic compounds and salts present in tree bark reinforce the nanocellulose, reducing its disintegration in water and increasing its strength.
