Innventia and BillerudKorsnäs Building Mobil Demonstration Plant for Nanocellulose Production
Fully delaminated nanocellulose consists of long (1-2 micrometres) microfibrils (5-20 nm in diameter) and has the appearance of a highly viscous, shear-thinning transparent gel.
June 26, 2014 - Innventia and BillerudKorsnäs announced that they have teamed up in the construction of a mobile demonstration plant for nanocellulose and to test the material in full-scale papermaking.
The project is financed by Vinnova, Innventia and BillerudKorsnäs.
According to Innventia, nanocellulose can be used as additives in papermaking to make lighter and stronger paper and board. It can also be used in a variety of other applications in the food, pharmaceutical, and construction industry.
This means that paper is given completely new properties and could replace plastics, for example, in many areas. More products could thus be produced from renewable and biodegradable raw material, Innventia said.
Since 2010, Innventia has operated a nanocellulose pilot plant at the research institute in Stockholm where "sufficiently large amounts of nanocellulose could be manufactured for research and development addressing paper applications."
In a unique collaboration between BillerudKorsnäs and Innventia, a mobile demonstration plant is now being built which makes it possible to produce nanocellulose on a large scale for use in full-scale trials on paper and board machines, Innventia said.
“Nanocellulose has a fantastic potential in paper applications as well is a number of other applications. This new project is exciting as it gives us the possibility to validate the potential in full scale,” says Mikael Ankerfors, Project manager, New Business Lab, BillerudKorsnäs.
“Innovation is at the core of our business model. To be part of this project and explore the potential of full scale production of nanocellulose is a perfect match with our mission to challenge conventional packaging for a sustainable future,” says Magnus Wikström, SVP Strategic Development, BillerudKorsnäs.
“This is a very important step. The availability of test beds and demonstration plants are often crucial for up-scaling new processes resulting from our research and development,” says Anna Wiberg, Director of Business Development Materials Processes, Innventia.
“Thanks to the collaboration with BillerudKorsnäs, the development towards new nanocellulose-based materials can take a leap. Later, we will offer more companies access to the demonstration plant as a support in their innovation processes,” says Torgny Persson, Vice President Material Processes, Innventia.
Nanocellulose (also called microfibrillated cellulose, MFC or nanofibrillated cellulose, NFC) is produced by delaminating cellulosic fibres in high-pressure homogenisers. Fully delaminated nanocellulose consists of long (1-2 micrometres) microfibrils (5-20 nm in diameter) and has the appearance of a highly viscous, shear-thinning transparent gel. The material has exceptional strength characteristics on a par with Kevlar, a lightweight material used to manufacture high-strength, durable materials.
However, in contrast to Kevlar and other materials based on fossil fuels, nanocellulose is completely renewable. There are a wide variety of potential applications for nanocellulose, including, for instance, the manufacture of both paper and board.
With regard to paper/board, nanocellulose could be used as a strengthening agent in paper with a high filler content. Other areas of application may be surface sizing and coating, e.g. as a barrier material (against oxygen, water vapour, grease/oil) in food packaging. Then there are applications in the field of nanocomposites, non-caloric food thickeners, emulsion/dispersion, oil recovery applications, cosmetic/pharmaceutical applications, and applications in the electronics sector.
