ABSTRACT: Calcium carbonates, ground and precipitated, have an established role in material engineering where they serve as fillers and pigments. In this study monohydrocalcite (MHC) was produced from artificial industrial waste brines as a means of sequestering CO2, and assessed as a potential functional filler, where its properties were compared with other minerals used in the industry. The results from the morphological analysis which compared MHC with the shapes and sizes of filler crystallites used in papermaking industry were deemed promising. The critical literature evaluation confirmed the potential of MHC as a functional filler: its density, hardness and RI were in-line with PCC fillers which have a well-established role in papermaking and other industries.
