Description

One of the potential applications of MFC, CNC and NFC in large volume is to use it as strength additives in paper and paperboard products that in most cases consist of mixtures of mechanical and chemical pulps. Nanocellulose can be used to improve the quality and performance of a broad array of paper and board materials, coatings and films, as well as nano-composite materials. MFC, CNC and NFC can be used as follows in papermaking applications; as strength additives, to enhance barrier properties in food packaging, to improved paper gloss, to reduce paper grammage and to enable smart packaging.

A major purpose of the project is to significantly lower the manufacturing costs and to facilitate the use of layer-by-layer technology by replacing the relatively expensive anionic component CMC (carboxymethylcellulose) with nanocellulose. To succeed, an industry-friendly system for cost-effective production of NFC (nanofibrillated cellulose), NLC (nanolignocellulose) and/or CNC (crystalline nanocellulose) must be developed. The idea of this project is to develop this type of system through optimization of fractionation and filtration systems where industrially available fine material fractions from pulp and paper manufacturing processes are tested.
