Who are we ?

InTechFibres Team

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.
