Testimonies of our graduates

Pauline DARCEL (class of 2019)

Pauline DARCEL (class of 2019) is an engineer in the Beauty division of the Cargill group at the European R&D center in Belgium

“Being interested in the formulation and in the fields of cosmetics, health and the food industry, I joined the ENSCR after two years of CPGE (Preparatory Class for Grandes Ecoles). I then followed the major Chemistry and Technologies for Life in 2nd year, then the Formulation specialty in 3rd year, which comforted me in my desire to work in R & D formulation. Following this training, I completed my final internship at L’Oréal, where I had the opportunity to work in Research & Innovation on the formulation of natural colors in the field of makeup. I learned a lot in practice during this internship, and that convinced me to continue in the natural cosmetics sector. Today, I work as an engineer in the Beauty division of the Cargill group at the European R&D center in Belgium. Cargill Beauty’s objective is to supply cosmetic raw materials with a high naturalness index to many customers in the sector. My mission within the laboratory therefore consists of researching and developing new natural cosmetic ingredients, drawing inspiration in particular from those already developed in the agrifood division of Cargill and by adapting them to a cosmetic application. Being a fairly recent branch of the group, in full development, innovation occupies an important part of our work, which is rather challenging and enriching. “

Hugo FOURNIER (class of 2019)

Hugo FOURNIER (class of 2019) is Engineer Business Manager at SOURCES
“Interested in environmental professions, I turned to the major Process Analysis Environment (EPA) before specializing in process engineering, and particularly in water treatment. This training allowed me to integrate the company SOURCES during my 3rd year internship in which I was able to supplement my theoretical knowledge with practical experience. I was therefore hired on a permanent contract at the end of my internship and I am now a Business Engineer. I am currently supervising two projects: one for the construction of a wastewater treatment plant and the other for the renovation of the sludge sector of an existing station. My job is to carry out the work as planned when responding to a call for tenders: finding subcontracting companies, directing them, managing interactions between the various trades, ordering all the necessary equipment when the station is running, manage the financial part of the site, etc. Then start up the new installation. This is a very comprehensive job since we are called upon to discuss the water treatment process as well as cyber security or even electricity with customers but also specialized companies which allows me to continue to learn about many topics. One of the advantages of this job is that there is no routine. I also really like the fact that it is an office job, of course, but in which I have to travel very regularly on construction sites to follow their progress or carry out meetings. “

Chloé PABLOS (class of 2019)

Chloé PABLOS (class of 2019) study engineer at CNRS
“During my course at the ENSCR, I followed the courses in the major Chemistry and Technologies for Life (CTV), Materials specialty, in double-course with the University of Rennes 1: Master in Solid and Materials Chemistry .I did my end-of-study internship at the LafargeHolcim research center in Lyon, where I studied the influence of mineral and organic additions on the hydration of cements for very specific applications. This internship was for me a first springboard towards employment: in fact, a position of research engineer in CDD was proposed to me in this company. Today, I work as engineer of study in development and characterization of inorganic materials for sodium batteries at the CNRS in Bordeaux, and this is, I think, one of the great interests of this training: it is possible to work in very varied fields of applications, ranging from cosmetics to construction, through energy while being aware of current environmental issues. “

Gwenaël DANIGO (Class of 2017)

Gwenaël DANIGO (class of 2017) Business Engineer at Sources
“Having always had a desire to work in the field of the environment which today requires special attention from our generation and future, it is at the ENSCR that I specialized in Process Engineering & Environment with the school’s EPA stream. In this training, I learned the theory, processes and techniques of water, air and waste treatment. It was during my 3rd year internship in the company SOURCES that I was able to deepen my theory and discover a concrete application in the field. Today, as an Engineer in charge of Business at SOURCES, I am responsible for several construction sites for sewage treatment plants, drinking water plants and rainwater storage tanks, turnkey. My job revolves around two main axes:
– Study phase: sizing, design of installation to respond to calls for tenders conducted by municipalities or communities;
– Site phase: supervision, management, monitoring and The start-up of the facilities. The responsibilities that were given to me upon my arrival in the company gave me a taste for the world of work and led me to discover several areas of activity that we are led to meet. This is why, I appreciate my job since beyond my training in the treatment processes that I encounter on a daily basis, my training continues day by day in other sectors of activity (electricity, civil engineering , automation…) closely linked to the process. ”

It was a very enriching experience and above all it allowed me to open doors for my integration into the world of work. After my internship, I continued to work for VEOLIA at the Rennes household waste incineration plant where I was in charge of several projects at the factory level. and I joined VEOLIA’s Technical Incineration Department for the Center-West region of France. My main missions today are the analysis and optimization of the functioning of the smoke and water treatment processes to ensure the achievement of the environmental performance of 7 incineration plants (project monitoring, work, regulatory aspect, …). I particularly appreciate in my work the versatility of the profession and the autonomy which is granted to me which allows me to fully develop my skills in the industrial world. “

Jérémy Bonneau (class of 2015)

Jérémy BONNEAU, Majeure EPA, technical studies and projects manager at SPL Eau du Bassin Rennais (class of 2015)
“Attracted relatively early in my course by environmental chemistry, I naturally turned to the EPA sector. This course was able to satisfy my curiosity and my thirst for learning in areas of interest such as water chemistry, treatment processes, analysis methods or statistics. After several internships in drinking water (R&D, BE) and a civic service in environment, I now use my skills at the service of the Local Public Water Company of the Bassin Rennais, company of production and distribution of drinking water. As a researcher, I work on a wide variety of projects such as monitoring the redesign of a UTEP, creating a pumping station, strengthening instrumentation, … An important part of my work also consists in monitoring the quality of water produced and in leading research and development projects on the 7 production sites of the SPL (iron removal,. emerging pollutants, pesticides, process performance, equipment mechanization,… In my opinion, the key skill for this position is a significant capacity for adaptation combined with a strong curiosity to quickly become relevant and versatile on the many themes proposed (chemistry, hydraulics, civil engineering, electrical, administrative, political, etc.). ). On the other hand, the interface with many interlocutors, such as plant or network operators, the community or even universities contributes to the richness of this position. Enough to continue to flourish after the ENSCR. “

Philippe Sauvignet, Veolia, Industrialization Manager within the Technical and Performance Department of Veolia Environnement SA. He is also an expert in drinking water.

“I am in charge of the industrialization of a new drinking water and wastewater treatment process for the Veolia group. In this context, I conduct process tests on the factory with pilot installations and other prototypes. Since 2007, I have been recruiting ENSCR engineering students. These students are for the most part well trained, competent and above all motivated by our professions. Obviously the training given at the ENSCR is a quality training which combines the necessary theory as well as practical application. This suits us very well because we are of course looking for well-made faces but also and above all young people full of dynamism. I found within the teaching team supports and relays of our needs as well as the requirements of our trades in terms of recruitment. Almost half of the BAC + 5 students that we welcome in this framework integrate the Veolia group. I am in contact with many of them long after their studies have ended and their visit to our test centers. It is therefore a big thumbs up that we can send to teaching within the ENSCR. “


Régis Guérin, Production BU Nutrition Manager at Eurofins Analytics.

“For more than 10 years, the Eurofins Analytics laboratory in Nantes has collaborated with the ENSCR and welcomes student-engineers, generally 1st year students, as part of their work placement. The objective and the purpose of this internship are focused on the discovery of the job of analytical production manager / technician in a private laboratory with an industrial approach to the organization in order to perform numerous analyzes in a minimum of time, but also be able to organize his work in order to carry out his daily planning and rigorously follow the analytical protocols in a spirit of accuracy. The student, by integrating the analytical units, is therefore brought to apply his theoretical and practical knowledge taught at the ENSCR but also to develop his personal skills, interpersonal skills, which is generally a rewarding experience for these young future graduates. In addition to these different missions, the trainee is supported in a research project or method reliability which will be integrated into his written report, which he will then present to a jury of teachers. The training provided by the ENSCR is recognized and appreciated by Eurofins Analytics, we have already hired student engineers for R&D project manager positions in our different Business Units, which clearly shows our confidence in their skills. “
