Who are we ?
« InTechFibres’ property – do not divulgate » - General Presentation/MPC/2018 2
Market / Society context …
• 150 to 200 milliard tons of biomass produced annually, of which 0.5 to 1
milliard tons are wood.
• In 2015, 178.5 million tons of pulp produced in the world, Europe
representing 24.5 % and France 1%. This world production is
characterised by :
75% of chemical pulps and 25% of mechanical pulps.
A growth of about 1% per year, mainly driven by the Asian demand.
Fluff pulp, dissolving pulp and BCTMP will count for the future.
• In 2016, 4.09 million tons of wood were used for the production of panel
boards and plywood products in France.
• InTechFibres partnership between CTP (French pulp and paper research
center) and FCBA (French Institute of Technology for forest-based and
furniture sectors) for increasing the forces in plant chemistry.
