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, …

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 …

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 …

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 …
