Julien Bourçois, quality manager of the Safe Metal group, explains thate “heat treatment consumes a lot of energy”, whether electricity or gas. In 2019, the company chose to set up a “energy management”. The key point: map consumption to determine the main uses and take measurements. Several actions have since been implemented: the automation of the ovens so that they are loaded continuously, “in order to optimize consumption”. This enabled savings of 150 tonnes of CO₂ in 2024, he explains. Second action: the installation of self-recovery burners, making it possible to recover gas and achieve savings of 20% on consumption. The project will be finalized in 2025. Third project: the installation of photovoltaic panels in the Colombier-Fontaine car park, a project which will be completed within a year.
On the side of Framatome, serving civil nuclear and defense, the question of energy consumption was little addressed before 2022. Adeline Lajoie, head of operational excellence and energy, explains that the company operates 14 furnaces gas, to heat modeled parts during sequences of five to ten cycles. She admits : “No one, apart from the accountant who processed the invoices, knew how we consumed gas until they threatened to cut us off. » The company is interested in it in 2022. “That’s where I took on the energy cap. » Several actions have been undertaken since then: instrumentation of tools to carry out consumption measurements, change of tools to optimize performance, switch to electric, cleaning of machines to avoid waste, and study of waste heat recovery. An audit is currently underway to go further into the different possible modes of operation to decarbonize.
After these interventions, several institutional and banking partners, such as Ademe, Banque des Territoires, Bpifrance and the Region, presented their assistance and support systems to decarbonize your business. Industrialists were able to interact directly with these players to analyze possible financial and technical solutions in the region. The meeting aimed in particular to strengthen links between manufacturers and solution providers. Hopefully this might have sparked some ideas.
