Marine oil pollution detected from space

oil pollution

Whether it is due to oil spills or cleaning out of tanks at sea, radar satellites can detect any oil slick on the ocean’s surface. Over 15 years ago, René Garello and his team from IMT Atlantique worked on the first proof of concept for this idea to monitor oil …

What happens to nanoparticles when they become waste?

nanoparticles

For the past twenty years, industry sectors across the board have been producing a wide range of nanomaterials. They have developed rapidly and with little in the way of regulation. This has led to a regulatory vacuum when it comes to the end-of-life management of these nanomaterials. Little is known …

ALGIMEL, a ‘marine’ polystyrene

ALGIMEL is an environmentally-friendly material which is used in a wide range of projects.

In the future, materials will not only need to be more efficient; it will also be essential that they are environmentally friendly. With this in mind, researchers from IMT Mines Alès who specialize in bio-sourced materials are working on this project.  Over the past few decades, they have been trying …

When microorganisms attack or repair materials

microorganisms

Some microorganisms can seriously damage structures made of concrete or stone, leading to billions of euros in damage. Others, on the contrary, have a positive effect as they are able to heal micro-cracks.   They are microscopic, but can cause billions of euros in damage. Microorganisms, such as bacteria, fungi …

Recycling carbon fibre composites: a difficult task

carbon fibre

Carbon fibre composite materials are increasingly widespread, and their use continues to rise every year. Recycling these materials remains difficult, but is nevertheless necessary at the European level for environmental, economic and legislative reasons. At IMT Mines Albi, researchers are working on a new method: vapo-thermolysis. While this process offers promising …

In search of forgotten cements

cements

Out of the 4 billion tons of cement produced every year, the overwhelming majority is Portland cement.  Invented over 200 years ago in France by Louis Vicat — then patented by Englishman Joseph Aspdin —Portland is a star in the world of building materials. Its almost unparalleled durability has allowed …

Sand, an increasingly scarce resource that needs to be replaced

sable, sand

Humans are big consumers of sand, to the extent that this now valuable resource is becoming increasingly scarce. Being in such high demand, it is extracted in conditions that aren’t always respectful of the environment. With the increasing scarcity of sand and the sometimes devastating consequences of mining at beaches, …
