Three Mile Island, Chernobyl, Fukushima: the role of accidents in nuclear governance

Stéphanie Tillement, IMT Atlantique – Institut Mines-Télécom and Olivier Borraz, Sciences Po Until the 1970s, nuclear power plants were considered to be inherently safe, by design. Accidents were perceived as being highly unlikely, if not impossible, by designers and operators, in spite of recurring incidents that were not publicized. This changed abruptly in 1979 with the Three Mile Island […]

Understanding data by touching it

Reading and understanding data is not always a simple task. To make it easier, Samuel Huron is developing tools that allow us to handle data physically. The Télécom Paris researcher in data visualization and representation seeks to make complex information understandable to the general public. Before numbers were used, merchants used clay tokens to perform mathematical operations. […]

What do we know about the environmental impact of biocomposites?

Bio-based materials are an alternative to those derived from fossil resources. They have been increasingly promoted in recent years. However, given the recent development of this sector, their real environmental impact is still relatively unknown. Joana Beigbeder, researcher in environmental analysis at IMT Mines Alès, provides an update on the life cycle analysis (LCA) of these […]

Corenstock Chair: a Trial Cylinder for the Heating Industry

As 2021 begins, IMT and elm.leblanc launched the Corenstock Industrial Chair to address issues in energy and digital transition in the domestic heating industry. What is the objective? Within four years, to present a demonstrator for the hot water tank of the future: more resistant, efficient and durable. Behind this prototype lies the development of […]

Do hospital staff feel prepared?

Marie Bossard, a specialist in the social psychology of health, has been studying the feeling of preparedness among hospital staff in the face of exceptional health situations in her PhD since 2018. She explores the factors that may influence this feeling to better understand the dynamics of preparation in health systems. The Covid-19 crisis is […]

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 […]

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 […]

What is life cycle analysis?

Life cycle analysis (LCA) is increasingly common, in particular for eco-design or to obtain a label. It is used to assess the environmental footprint of a product or service by taking into account as many sources as possible. In the following interview, Miguel Lopez-Ferber, a researcher in environmental assessment at IMT Mines Alès, offers insights […]
