To manufacture some industrial products such as adhesive tape, rubberised fabrics, pharmaceuticals and cosmetics a large quantity of chemical solvents is used. Regulations on the release of these solvents into the air that keep getting more stringent as well as economic reasons that encourage recycling have contributed to the spreading of plants for the destruction and recycling of the solvents. The use of nitrogen in these plants, connected both to the cryogenic properties of the nitrogen and to its inertia, seems to be the most modern solution and also the one that is most suitable to environmental protection needs.

SOL can promote the installation of plants for solvent destruction and recycling for a great variety of users also by associating with other plant engineering companies specialised in this field.
