Intensive mechanical milling in the extreme can lead to particular effects for mineral materials (glass, slag, fibres, ash, etc.) and organic materials (wood, plants, micropollutants, etc.). In the dry, this can be micronisation, amorphisation and increase in specific surface and chemical reactivity, while in the wet (using water or a solvent), intensive grinding leads to the extraction of molecules of interest and a subsequent extraction stage. These expertise topics are the latest developments brought through CTP and applied especially to the everyday inert waste sector, construction materials and metallic residue, opening up towards the food industry and fine chemistry.
