CELLUWIZ, an innovative project !

CelluWiz : new video for new 100% cellulosic products

The community of CELLUWIZ is proud to release a short video presenting the objectives and the partners of the project ! "Combining two innovative technologies to produce high barrier all-cellulose packaging materials”... that is the challenge! This has been turned into pictures to make it universally accessible and to reach a broad audience... Come with us to imagine the 100% cellulosic packaging of the future! More info on

Ultracell project, towards the glue-free bonding of papers and boards!

  The Centre Technique du Papier, coordinator of the UltraCell project! 

The UltraCell Project, supported by the ANR, coordinated by the CTP in collaboration with the 3SR and LGP2 laboratories in Grenoble and the SONIMAT company in Nantes, aims to develop an industrial process for the glue-less bonding of papers and boards. This process should lead to eliminate glues and related food contact issues, to move towards mono-material packaging almost entirely bio-based, to reduce the environmental impact related to the overconsumption of energy and the management of waste in the recycling of packaging and to facilitate the recycling of packaging by eliminating residual glue points that impact the productivity of paper machines. The objective is to develop an ultrasonic welding process suitable for papers and boards that achieves performance at least equivalent to existing bonded joints, in terms of quality of adhesion, energy cost and production rate for a wide range of papers and boards (rigid packaging, flexible packaging, graphic papers, tissues ...).

The CTP, partner of the European project WOODZYMES

WoodZymes project, a Research & Innovation Action of the H2020 “Bio-Based Industries”

The Biological Research Center (CIB) from the Spanish National Research Council (CSIC) will host on 2018, June 14th (in Madrid, Spain), the kick-off meeting of the WoodZymes European Project on “Extremozymes for wood-based building blocks: from pulp mill to board and insulation products”. This is a H2020 Research & Innovation Action funded with € 3.25 million by the “Bio-Based Industries” Joint Undertaking ( and coordinated by Dr. Susana Camarero from the CIB Group of Biotechnology for Lignocellulosic Biomass. The CTP is partner of this big project! The project goal is to develop tailor-made enzymes able to work under the extreme operation conditions of pH and temperature required by the wood-processing industries to remove or modify hemicelluloses and recalcitrant lignin protecting cellulose in the plant cell wall. This will enable selective valorisation of currently underutilised biomass fractions to provide high-value bio-equivalents of petroleum-derived chemical building blocks.

PhénoLiq project: towards bio-based aromatics!

CTP, partner of the PhénoLiq project: towards bio-based aromatics!

The PhénoLiq project, supported by the French Government (ANR), coordinated by the LRGP from Nancy (Laboratory of Reactions and Process Engineering) and in collaboration with IRCE Lyon and CTP from Grenoble, focuses on the valorization of industrial lignin from black liquors of pulp mills. The goal is to develop a stepped and continuous liquefaction process of lignin to produce phenols, coupling depolymerization, catalytic conversion and separation / purification. Applied to two industrial sites, the extraction of suitable lignin, transformation and integration into the pulp mill will be determined at the lab scale and semi-pilot scale, then extrapolated on an industrial scale by modeling and simulation.

The DES winning recipe...!

The DES (Deep Eutectic Solvents) were selected as the most innovative breakthrough technology in the TwoTeam Project ( The European project PROVIDES brings together over twenty european partners aiming to produce virgin and recycled pulps with a radically innovative approach, based on these solvents’ potential. The project launch meeting (kick-off meeting) took place at the ISPT (Institute for Sustainable Process Technology) on September 15, in Amersfoort, Holland and the CTP was a part of it.

Funky... Cellulose Fibres!

To answer the social and environmental pressures to reduce the environmental impact of packaging, CTP, in partnership with European SMEs, develops new, more efficient and greener packaging by taking advantage of fibrous components of agricultural waste (oat husk). These biobased packaging of latest generation, based on green carbon, are expected to meet some of those expectations. For more information, click the following link:

Two new R&D projects

Last March, at the NAMIPROD project launch, the CTP welcomed 24 companies interested in the new developments carried out in our research Centre enabling the creation of innovating materials. The representatives of the papermaking industry major groups came to the CTP to exchange ideas on the optimisation of the Cellulose Micro-/Nanofibrils (MFC/NFC) production.  An occasion to be acquainted with the NaMiCell new production pilot, put into service in the CTP’s premises by end 2012. The launching was also an opportunity to:
- envisage future collaborations with the CTP
- discuss about the potential transfer to the industry of the value created at the CTP.
At the same time, the CTP organised the launching of the TERPIN project which aims at putting into good use the aqueous and gaseous rejects emitted by the chemical pulps and mechanical mills whose terpenic compounds would be caught. The meeting attracted dozens international clients aware of the thematic regarding the diminution of rejects and the recovery of papermaking by-products....
