Due to greenhouse gas emissions in industrial production, global warming and the resulting climate change pose significant threats to a liveable world. The emission of carbon dioxide, which is released as a result of industrial activities, is the most important component that triggers the global warming process. The use of waste material, which is the result of industrial activity, as raw material within the framework of circular economy is of vital importance in terms of the use of sustainable resources. The problem of phosphogypsum, which is released during the production of phosphoric acid, can be eliminated by the Merseburg process. With such waste minimisation, the destruction caused by emission gases such as carbon dioxide in the atmosphere will also be prevented. In this evaluation study, the use of carbon dioxide gas as a raw material is discussed, while reducing the emission values of industries such as cement and thermal power plants that cause large amounts of carbon dioxide emissions from phosphogypsum waste. Although an ammonium sulphate production is foreseen with the evaluation of carbon dioxide and phosphogypsum waste with the Merseburg process, the effect of the impurity content of the waste material used on the recommended ammonium sulphate concentration will be an important research topic. Various protocols are being worked on worldwide in order to minimise the emissions on international scale. The use of the Merseburg process for this and similar processes will provide significant advantages to the manufacturer in reaching the targeted emission amount.

We consulted the works of Agayr et al[40], Zemni et al[41], Bouargane et al[42], Mechi et al[43], and Hammas-Nasri et al[44] to assign the FT-IR peaks. The observed bands at 3504-3393 cm−1 and 1682-1618 cm−1 were attributed to the stretching and deformation vibrations of OH − and H-O-H groups from water molecules, respectively, as depicted in the figure.…”

This study aimed to investigate the effects of phosphogypsum addition on ceramic membrane properties. In this regard, clay and phosphogypsum were characterized using FTIR and laser particle sizer. The ceramic paste was prepared by incorporating varying amounts of phosphogypsum (10 to 50%), followed by molding using a semidry-pressing process at 10 bars pressure and sintering temperature at 900℃. The raw materials and prepared membranes were analyzed using FTIR, laser particle size, contact angle, porosity, and mechanical strength to evaluate the properties of the resulting ceramic membranes. The study showed that as the amount of phosphogypsum increased from 10% to 50%, the membrane's hydrophilicity significantly increased, while its mechanical strength decreased by 35% and porosity increased by 26%. Moreover, the permeability of distilled water also showed a significant increase of 67% when the amount of phosphogypsum was increased from 10% to 50%.These observations suggest that phosphogypsum can significantly influence ceramic membrane properties, which may have implications for its use in various membrane applications. The findings of this research contribute to our understanding of the potential use of phosphogypsum as a valuable material for ceramic membrane production, with important implications for sustainable waste management practices. Future studies can focus on exploring the suitability of these ceramics for various applications and their environmental impact.
