In parallel with this technological advancement, Valmet is also proud to celebrate the success of Estelle Lupetti, who was recently awarded the Prix de la Cellulose 2024 for her outstanding thesis project. Now a process engineer at Papeteries des Vosges, Estelle tackled a critical quality issue in pharmaceutical paper production: the detachment of eucalyptus vessels during offset printing. Her work, supported by Valmet Fiber Image Analyzer (Valmet FS5), led to a 30% reduction in vessel detachment and a 25% decrease in energy consumption during refining.
The analyzer played a key role in her research, offering ultra-high-definition optics, automated image processing, and customizable modules based on neural networks. Estelle’s findings have already led to concrete recommendations for Papeteries des Vosges, including refining optimization and the exploration of enzymatic refining for improved sustainability.
These two stories, one of technological innovation, the other of scientific excellence, illustrate Valmet’s ongoing commitment to supporting the industry’s transition to a more sustainable and high-performance future.
