Nanocellulose - for the first time on a large scale
The world's first pilot plant to produce nanocellulose was inaugurated yesterday by research company Innventia in Stockholm. The facility makes it possible to produced nanocellulose on a large scale for the first time and is an important step towards the industrialisation of a new energy efficient manufacturing process.
“ With larger volumes, we can study the use of nanocellulose in applications that require more material, "says Michael Ankerfors a Research Manager at Innventia.
Nano Cellulose is a material derived from wood fibres. It has exceptional strength characteristics of the class with Kevlar, a light weight material. However, in contrast to Kevlar and other materials based on fossil fuels, nanocellulose is completely renewable.
Previously, the production process was much too energy-consuming, for the commercialisation of nanocellulose to be conceivable, but due to the process developments carried out by Innventia, the energy consumption has been reduced by a total of 98%, representing a saving of 29 000 kWh per tonne. To give a comparison, the heating of a normal sized house takes approximately 18,000 kWh per year.
“For a long time, there’s been a great deal of interest from the industry in utilising nanocellulose as a strengthening component in other materials, such as paper, composites and plastics,” relates Mikael Ankerfors. We can also create new, more efficient and renewable barrier films for food packaging.
In order to develop applications, such as paper and composite materials, the raw material produced in a lab is not sufficient. The new pilot plant is designed for a production at 100 kg per day.
“ We can now make runs at our pilot paper machine. We now also have the opportunity to continue the development of the process and to show interested parties how it could work in reality. “
All sub-steps are now in place in the process and last week the production began.
“As the only company in the world, we’re extremely proud to be able to offer the industry real opportunities to participate in this field, which is so important for the future,” concludes Mikael. “Now we begin to work towards the next step: the installation of a full scale process with a partner in the industry.”
The inauguration was attended by representatives from the industry as well as, public funders and participants in research related to nanocellulose. Besides looking at the new facility opportunity was offered to take a closer look at samples of nanocellulose and various examples of applications such as barrier films, textile fibers and nano-foams made from nano-cellulose.
