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 […]
In August 2019, it was announced that the Astrid project for sodium fast reactors (SFR) was to be abandoned. In late 2020, Stéphanie Tillement, a researcher at IMT Atlantique, analyzed the rationale behind this abandonment in an article for I’MTech. But what is the global situation? Does this technology still have a future? Stéphanie Tillement and her […]
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 […]
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 […]
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. Increasing production of […]
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 […]
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 […]
The QuASPEr project studied the Canche river basin in northern France to better understand the phenomenon of soil erosion and its related consequences. This knowledge aims to develop effective land management methods for municipalities without negatively affecting farmers’ work. Heavy rain, dry land, sloping ground that has been tilled… and the soil erodes. This […]

The Destiny project proposes a new process to manufacture parts for the railway and aeronautical industries. It uses a thermoplastic resin, which enables the materials to be recycled while limiting the pollution associated with manufacturing them. It is increasingly critical to be able to recycle products so as to lower the environmental cost […]
