👉 On November 27 and 28, 2025, during the traditional Papetières Days organized by the ATIP and COPACEL associations in Paris, we met with our customers at the CTP's stand no. 7.
🥇🏆 At the Concours des Palmes de l’Innovation (Innovation Awards), the CTP, represented by Bruno Carré and Gilles Lénon, once again took first place and won a magnificent GOLD PALM! We are very proud of our teams! This competition, exclusively reserved for participating companies, suppliers, universities, and research centers, is a great springboard for promoting paper-making technologies! Sixteen companies competed this year, and the CTP received unanimous praise and congratulations for its entry on “compression refining: an innovative solution for increased productivity!”

Bruno CARRE, Project Manager, and Gilles LENON, Managing Director, who received the award, made a point of thanking the manufacturers who support the CTP and more specifically this project, as well as the CTP staff involved in this technology: Marie Christine ANGELIER, now retired but a pioneer at the time in working on the mixer, then Frédérique ENTRESSANGLE and Rémi COGITORE who took over from her.... On the BIVIS pilot project, Valérie MEYER alongside François COTTIN at the time, then Mel-Alexandre PETRILLO, Loevan LEBORGNE, and Virginie SCAVONE... Not to mention the physical testing staff who characterized all the paper sheet produced; and finally Flavien Lozano, who is now taking over from Bruno on this subject.
This is a major challenge, as the technology now needs to be industrialized in collaboration with CLEXTRAL, a partner in the project.
This award highlights the CTP's innovative projects and will undoubtedly open the way to new positive opportunities for the entire Center.
Well done, everyone! 👏
A High-Value, High-Performance Process
Compression refining enables:
Preliminary industrial trials demonstrate substantial benefits:
To accelerate scale-up, the CTP has partnered with Clextral to adapt BI-VIS twin-screw extrusion systems. These machines reproduce the compression refining effects observed in the lab while processing several tons per hour, making them ideal for industrial validation. Industrial demonstration trials are underway on a small industrial paper machine to confirm the strong potential of this patented technology under real production conditions.
Why Does It Matter?
Compression refining is emerging as one of the most promising innovations in the papermaking sector, offering:
✔ lower energy use,
✔ higher product performance,
✔ improved environmental impact.
For papermakers, recyclers, packaging producers and fibre-based industries, this technology is a strategic lever to improve productivity, reduce production costs, and strengthen sustainability efforts.

SUMMARY of the PROJECT | Compression Refining: An Industrial Innovation to Boost Productivity and Reduce Energy Consumption
In response to today’s major challenges in the pulp & paper industry—rising energy prices, increasingly variable fibre resources, environmental pressures, and the demand for higher mechanical performance—the CTP has developed a breakthrough technology: Compression Refining. Unlike conventional shear-based refining, compression refining modifies the structure of cellulose fibres without damaging them, enhancing fibre flexibility, bonding capacity, and conformability, while maintaining excellent drainage.A High-Value, High-Performance Process
Compression refining enables:
- Significant gains in mechanical strength, even at low °SR levels.
- Strong reduction of fines generation, improving drainage and machine runnability.
- Minimal fibre cutting, preserving the contribution of long fibres.
- High sheet permeability, ideal for packaging, tissue and technical grades.
- Enhanced use of alternative fibres, such as recycled fibres or annual plants.
- Tests carried out at lab scale, pilot scale, and semi-industrial scale show that sheets refined by compression are stronger, more open, and more efficient, even when using more fragile fibres—an important step towards a more circular fibre economy.
Preliminary industrial trials demonstrate substantial benefits:
- 15–25% reduction in electricity consumption, thanks to greatly improved drainage (lower vacuum demand).
- ≈15% reduction in steam consumption, due to a more open sheet structure.
- Economic gains of 15–20 €/ton, based on first modelling results.
- These gains make it possible to produce lighter yet stronger papers, opening opportunities for grammage reduction in grades traditionally difficult to drain.
To accelerate scale-up, the CTP has partnered with Clextral to adapt BI-VIS twin-screw extrusion systems. These machines reproduce the compression refining effects observed in the lab while processing several tons per hour, making them ideal for industrial validation. Industrial demonstration trials are underway on a small industrial paper machine to confirm the strong potential of this patented technology under real production conditions.
