Crystalline Nanocellulose™ (CNC)

In the manufacturing of crystalline nanocellulose, there is a high usage of acid due to the large volume of raw material, resulting in increased recycling costs. Typically, dialysis is employed to purify crystalline nanocellulose, but this entails high expenses and significant water consumption.

Noram has developed an enhanced method for manufacturing crystalline nanocellulose, including a continuous process where the raw material is compressed. This results in a reduction of acid usage by two-thirds compared to previously applied processes. Additionally, water consumption has decreased by 80% through the use of electrodialysis in conjunction with ion exchange resins during the purification of crystalline nanocellulose.
