Bio2X uses fractionation technology, developed by Fortum's interest company Chempolis, that can extract not only cellulose but also hemicellulose and lignin for high-value products.

Straw is back in demand
Straw, such as wheat or rice straw, is abundantly available across the globe. After harvesting, it is usually discarded or even burned. However, as straw contains all three biomass fractions, it can be refined for high-value use.
Bio2X uses wheat straw as raw material while the grain is used for food, which allows for more efficient production on the same land area. The resulting fractions from the fractionation process have numerous applications globally, such as textiles, biocomposites, packaging materials, cosmetics and resins.
Currently there are virtually no advanced straw-based materials on the market. Straw fibres were used widely in the European paper industry until the 1950s, however, due to technical and financial issues arising from the refining processes, the production has almost completely disappeared.
Today, consumers are increasingly aware of sustainability issues and industries are under pressure to improve their sustainability performance. There is a strong pull in the market for straw-based applications, which are still extremely rare. Depending on the application, straw-based materials can be recyclable at their end of life.
