Arsenic contamination of water: Detection and treatment challenges

Arsenic

Arsenic contamination of water, whether surface water or ground water, affects many parts of France. Such contamination may be the result of anthropogenic causes, linked to mining operations for example, or of natural causes in relation to changes in geological formations, as is the case in many countries such as …

Trains made with recyclable parts

Photographie d'un train Regio2n, même modèle que le démonstrateur en résine thermoplastique développé par le projet Destiny

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 …

Temporary tattoos for brain exploration

A team of bioelectronics researchers at Mines Saint-Étienne has developed a new type of electroencephalogram electrode using a temporary tattoo technique. As effective as traditional electrodes, but much more comfortable, they can provide extended recordings of brain activity over several days.    The famous decalcomania transfer technique – made popular …

A sorting algorithm to improve plastic recycling

plastics

Producing high-quality raw materials from waste is contingent on effective sorting. Plastics from waste electrical and electronic equipment (WEEE) are no exception. To help solve this problem, researchers at IMT Mines Alès have developed a selective automation algorithm designed for these plastics. It can be integrated in new industrial-scale sorting …

Interactions Materials-Microorganisms

Christiine Lors

This book is devoted to biocolonization, the biodeterioration of materials and possible improvements in their performance. Many materials age according to their use and their environment. The presence of microorganisms can then lead to biodeterioration. However, these can also help protect structures, provided their properties are used wisely. Christine LORS, …

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 …

Polybioskin, natural skin through more ethical products

Polybioskin

Skin contact products, whether for medical, sanitary or cosmetic purposes, have two major drawbacks: they are neither recyclable nor biodegradable. The Polybioskin H2020 project aims to correct these aspects which are out of step with consumers’ growing environmental awareness and concerns. Launched two years ago, the Polybioskin project brings together …
