INEOS Calabrian produces sulfur dioxide through a proprietary process called  SOClean®. Rather than burning sulfur using ambient air - like most companies do - INEOS Calabrian creates a chemical reaction between sulfur and pure oxygen. As pure oxygen is more sterile this leads to consistently exceptional purity levels of sulfur dioxide and its derivatives. By using the best raw materials - and maintaining tight control over their production - INEOS Calabrian guarantees high quality and consistency of its products.

The unique  SOClean® process has a very low environmental impact. Neither nitrogen nor sulfur trioxides are produced. There's no process wastewater, so nothing is discharged into waterways. The  SOClean® process requires less water overall, and creates less landfill waste too. In days of increased consumer scrutiny, using raw materials with a low environmental footprint will benefit your organization.

Both facilities use INEOS Calabrian's proprietary SOClean® process.
