Approximately 75%wt is recycled, with the majority going into the production of gypsum boards ... is an important dilemma for our society. As is well known, there are a wide variety of carbon capture and storage technologies to reduce CO 2 emissions .

The flue gas desulfurisation process produces high-quality FGD gypsum. Compared to mined natural gypsum, the industrially produced gypsum is purer, therefore offering a wide range of environmentally friendly applications. This turns the output of flue gas desulfurisation into a basic material for industries around the world. From agriculture ...

These side products are formed in the flue-gas desulphurization plants (FGD) of power stations which are fired with fossil fuels. In Lünen, Remondis transforms these FGD gypsums into high-quality additives and binders which are then supplied to the gypsum industry under the trade name of "RADDiBIN" as raw material for different applications.

In efforts to mitigate CO 2 emissions, various carbon capture and storage (CCS) technologies have been developed. Among these, mineral carbonation has emerged as a highly promising option. ... FGD-gypsum, comprising finely grained Ca-bearing minerals, is a promising alternative to other Ca-rich substances in carbonation …
