Circular economy, environmental assessment and environmental budgeting

To implement a robust and durable circular economy strategy, it is important to assess its environmental impacts. Valérie Laforest and Natacha Gondran, both researchers at Mines Saint-Étienne, explain the reasons for incorporating an absolute environmental sustainability assessment method and the underlying concept of “environmental budgeting“. The lifestyles of our contemporary societies are exerting constant and […]

Decontaminating and treating waste from the steel industry

The manufacture of steel produces mineral residues called steel slags, which are stored in large quantities in slag dumps. These present a dual challenge. On the one hand, they are potentially harmful for the environment and health, and on the other hand they are a useful resource for certain industries. The HYPASS project at Mines […]

Carbon-free hydrogen: how to go from gray to green?

The industrial roll-out of hydrogen production only makes sense if it emits little or no carbon dioxide. Researchers at IMT schools are working on various alternatives to the use of fossil fuels, such as electrolysis and photocatalysis of water, plasma pyrolysis of methane, and pyrolysis and gasification of biomass. Currently, the production of one ton […]

Power-to-gas, when hydrogen electrifies research

Hydrogen is presented as an energy vector of the future. In a power-to-gas system, it serves as an intermediary for the transformation of electricity into synthetic methane. The success of this energy solution depends heavily on its production cost, so IMT researchers are working on optimizing the different processes for a more competitive power-to-gas solution.

Hydrogen: transport and storage difficulties

Does hydrogen hold the key to the great energy transition to come? France and other countries believe this to be the case, and have chosen to invest heavily in the sector. Such spending will be needed to solve the many issues raised by this energy carrier. One such issue is containers, since hydrogen tends to […]

Fuel cells in the hydrogen age

Hydrogen-powered fuel cells are recognized as a clean technology because they do not emit carbon dioxide. As part of the energy transition aimed at transforming our modes of energy consumption and production, the fuel cell therefore has a role to play. This article will look at the technologies, applications and perspectives with Christian Beauger, a […]

Turning exhaust gases into electricity, an innovative prototype

Jean-Paul Viricelle, a researcher in process engineering at Mines Saint-Étienne, has created a small high-temperature fuel cell composed of a single chamber. Placed at the exhaust outlet of the combustion process, this prototype could be used to convert unburned gas into energy. Following the government’s recent announcements about the hydrogen industry, fuel cells are in […]

Étienne Perret, IMT-Académie des sciences Young Scientist prize

What if barcodes disappeared from our supermarket items? Étienne Perret, a researcher in radio-frequency electronics at Grenoble INP, works on identification technologies. His work over recent years has focused on the development of RFID without electronic components, commonly known as chipless RFID. The technology aims to offer some of the advantages of classical RFID but […]

AI for interoperable and autonomous industrial systems

At Mines Saint-Étienne, researchers Olivier Boissier, Maxime Lefrançois and Antoine Zimmermann are using AI to tackle the issue of interoperability, which is essential to the industry of the future. The standardization of information in the form of knowledge graphs has allowed them to enable communication between machines that speak different languages. They then operate this system […]

Innovative approaches to recycling brominated plastics

Recovering untreated plastic materials and putting them back into the recycling loop through a decontamination line is the challenge of thesis research by Layla Gripon, a PhD student at IMT Lille Douai. These extraction methods contribute to a comprehensive approach to recovering plastic materials, in particular brominated plastics. High consumption of electronic devices implies a […]
