Portrait of Anaëlle MARCHE, engineer at Vinci Energies
Discover the portrait of a female engineer Arts et Métiers, now working at Vinci Energies.
Students at the Lille Campus are working on creating a "just-in-time" logistics flow on the educational line.
Under the guidance and supervision of Anthony QUENEHEN and Ana-Sofia JESUS GONCALVES, Romane COURAU, Vianney FERREY, Lina OUHAMMOU, and Emma SOUSA, second-year students in the Grande Ecole Engineering Programme at the Lille Campus, are working together as part of their PJT2A project to create a practical assignment aligned with the curriculum for future second-year PGE students.
In your opinion, which emits more CO₂? Attending classes in person or remotely?
To answer this question, students in the Grande Ecole Engineering Programme Angers campus carried out asecond-yeareducational project.

Reducing food waste through packaging using micro-layer extrusion technology
PIMM, whose expertise in materials and processes is widely recognized, seeks to promote micro-layer polymer extrusion technology at the European level.
The H2020 MyPack project, " "Best markets for the exploitation of innovative sustainable food packaging solutions," which ran from 2017 to the end of 2021, aimed to establish guidelines for better integrating bio-based and/or biodegradable and recycled polymers into food packaging by using new materials or new packaging technologies. The aim of this €150,000 project is to maintain and improve the quality of food products by improving food safety and reducing food waste and the environmental footprint of packaging materials.
Observing layers with cutting-edge technologies
Among the 18 European partners involved in the project, Alain Guinault, research engineer and deputy director of PIMM, Lauriane Truffault, design engineer, and Anne Grandmontagne, technician at CNAM in the Polymers and Composites team, participated in the project on behalf of the PIMM laboratory.
The team used polymer micro-layer extrusion technology and atomic force microscopy to observe the layers. Thermal analyses were carried out to observe the effects on the materials. The main difficulty was conducting these tests with very little material, given that its cost was very high due to its development during the project (more than €1,000/kg).
Manufacturing films that are half as thick and recyclable
PIMM has validated a proof of concept for the manufacture of PET (polyethylene terephthalate) films commonly used in food packaging. Reels of extruded and biaxially stretched films have been produced. The addition of 7 to 10% by weight of PEF (polyethylene furanoate) using micro-coating technology made it possible to halve the thickness of the PET films while preserving their gas barrier and mechanical properties despite the fragility of PEF, and at the same time making them recyclable.
Continue research on the micro-layer extrusion process
The PIMM "Polymers and Composites" research team is currently working on understanding the mechanisms behind the improvement of the mechanical properties of films in relation to the micro-layer extrusion process.
Thanks to DIMMaTerRE, one of nine Major Research and Innovation Domains (DIM) certified by the Ile-de-France Region for the period 2022-2026, a postdoctoral fellowship has been funded to study this scientific question.

Denis Lagadrillère, winner of the SF2M Jacquet Prize
Organized by the French Society of Metallurgy and Materials (SF2M), this award honors Pierre Armand Jacquet’s contributions to metallography, particularly in the areas of electrolytic polishing and the use of replicas for fracture analysis.
Denis Lagadrillère, an AMVALORengineer at LaBoMaP, won first prize.
HUM’AM, the energy to pass on
Students from the Specialized Engineering Program at the Arts et Métiers campus Arts et Métiers Paris, members of the HUM'AM association, are committed to sharing the skills and knowledge they have acquired during their studies at Arts et Métiers helping disadvantaged populations.
An Italian-style internship
Combining an interesting internship with la dolce vita is possible!
This is the choice made by Hamadi, a third-year student at the Bordeaux campus, who completed his internship at the Polytechnic University of Milan.
