IA-03 Bio-based chemicals and/or materials from woody residues

Expertise :

-Biomass treatment processes for the extraction of compounds of interest

-Valorization of unexploited lignocellulosic forest biomass (hedges, coppices, knots, bark) for the production of bio-sourced additives such as MFC or dissolved cellulose

-Valorisation in molded cellulose, injection

-Extraction of high value-added compounds (turpentine, soap, fatty acids, resin acid, polyphenols, etc.) by different solvent-free extraction techniques (e.g. twin screw) preserving the values/properties of the fibers for papermaking

Capabilities :

—Depending on the unexploited forest biomass, different scenarios can be considered:

—< 100 tons/day: decentralized mini-mill concept for the versatile production of pulp, for example to the production of molded cellulose packaging or tissue paper (local production, decarbonization, drying energy savings)

—> 100 tons/day: integrated plants for the economic production of bleached pulp and production of MFC

—Characterization of biomass (lignin content, resin content, etc.) by NIR and chemical analyses (fiber morphologies)

—Ongoing partnerships with leading industrialists in the forestry sector

—Capabilities for laboratory scale tests or semi-industrial pilots (cooking, bleaching, twin-screw extruder…)

The Centre Technique du Papier (CTP) is an impact-driven organization and a key player in the ecological transition for the paper, board, fiber-based packaging and biomaterials industries. It supports companies and market players in adopting new materials, optimizing production and converting processes, and improving the environmental performance across the full life cycle of their products.

Equipped with pilot-scale platforms, CTP provides R&D, consulting, expert assessment, and laboratory and pilot services for the pulp, paper, board and related industries (including converters and printers).

Thanks to its expertise in fibers, recycling, plant-based chemistry and barrier solutions, it contributes to the development of sustainable alternatives to plastics and strengthens the competitiveness of the entire value chain.
