Biorefinery – Simultaneous production of fibres, energy and chemicals
Increasing costs– Energy and wood
Decreasing trend prices on pulp Biorefinery is the solution
– Handling of large volumes of biomass– New pulp mill products– New efficient separation processes – Add “side” processes
Innventia approach– Kraft/soda pulp mill platform– Focus on the major components– Efficient separation process and mill integration
Lignin carbon fibres

Lignin can make difference
650 000 ton pulp/year
10% lignin extracted = 33 000 ton
… 16 000 ton carbon fibres
…can replace 40 % steel in 160.000 cars
