Ceramics already offer a certain number of solutions associated with the environment for applications in the areas of toxic gases given off by industry, catalytic converters or water or waste treatments through filters of various kinds.

Filtration membranes, catalysts or gas detection sensors are made using different oxides and rare earths, sometimes processed in the form of thin layers and integrated into hybrid circuits. Cordierite is one of the leading materials of the auto industry for making catalytic converters.

The inerting of certain types of nuclear waste is also an outlet for materials of the glass-ceramic type that then make it possible to find adequate solutions to problems of ageing waste.

The food processing industry uses bio-treated filters to filter various substrates of liquids requiring the use of selective barriers.
