Fassasorb is a range of Hydrated Lime products specifically developed to neutralise acidic components in industrial flue gases. Thanks to the soft burning of limestone and an optimised hydration process, Fassasorb offers a high specific surface area and ideal pore volume to effectively neutralise gases and remove acidic pollutants such as HCl, HF, and sulphur oxides.

The product is particularly suitable for waste incineration plants and industrial processes requiring reliable flue gas cleaning solutions. The purity of our lime and its exceptional reactivity guarantee superior performance compared to standard products, enabling you to meet the most stringent environmental regulations while optimising reagent consumption.
