Innventia researcher is awarded SEK 500,000 for carbon fibre research

Published 27/02/2013

Innventia’s Hannah Schweinebarth has been awarded this year’s Skills Prize by the Gunnar Sundblad Research Foundation. The prize of SEK 500,000 will be used to develop new knowledge on the production of carbon fibre from the wood raw material lignin.

Hannah Schweinebarth is a young employee at Innventia’s Biorefinery Processes and Products group. There, she carries out research within the focus area Lignin & Carbon, which covers the entire lignin production chain from black liquor to end products, such as lightweight carbon fibre materials.

Carbon fibre is strong and light, with many applications, especially in the automotive industry. Today, demand is mainly limited by the high cost, with the petroleum-based raw Hannah Schweinebarthmaterials and fibre spinning accounting for around 50 percent of the cost. Lignin, a substance that is found in wood but removed during kraft pulp production, has great potential for use as a raw material for manufacturing carbon fibre. Innventia has extensive experience in the production and characterisation of lignin from black liquor. Innventia worked with Chalmers University of Technology to develop the LignoBoost process (now owned by Metso), making it possible to extract a very pure lignin that could be used as a raw material for carbon fibre. The first industrial LignoBoost plant is now starting up at Domtar’s pulp mill in Plymouth, USA.

Thanks to the Skills Prize, Hannah will be spending six months at the Oak Ridge National Laboratory (ORNL) in Tennessee, USA. ORNL is one of the world’s leading “green energy” research centres, and is currently building a pilot plant which will produce about 25 tonnes of carbon fibre from lignin each year. This will enable Hannah to learn more about the properties of lignin and how they affect the properties of carbon fibre. The University of Tennessee will also be involved.

“It’s great fun!” says Hannah. “The prize represents an excellent opportunity for development, both professionally and personally. I get to come to a new country and an environment that provides completely new aspects for what I’m doing. I think that lignin offers tremendous potential, and it’s fun to be involved.”

“Carbon fibre from lignin is a new and expanding area for us, and one where we are now investing in more advanced equipment for further development,” says Peter Axegård, Director of Innventia’s Biorefining business area. “Knowledge building is also very important in terms of acquiring the necessary skills. We are therefore looking forward to this collaboration with ORNL, which will benefit Sweden and Innventia in many ways.”

About the prize
The Gunnar Sundblad Research Foundation’s Skills Prize has been awarded annually since 2007. The prize aims to promote the development of the Swedish pulp and paper industry towards new and improved products and services that can meet today’s increasingly tough competition. The prize enables a researcher from the Swedish research and innovation system to work at a foreign research environment in order to develop, make contacts and bring home new knowledge. The Gunnar Sundblad Research Foundation Board is appointed by the Swedish Forest Industries Federation Board. Find out more at
