| Abstract Scope |
There is a global effort to reduce the energy demand and carbon dioxide emissions from glass manufacture to meet the current net zero targets for a sustainable environment. Wollastonite (CaSiO3), has been identified as a carbon-free source of calcium oxide potentially capable of partially or completely replacing limestone in glass batches whilst also delivering faster melting kinetics, leading to energy saving during glass manufacture. Different lab-scale experimental analyses have been carried out to ascertain the viability of wollastonite as a limestone substitute in soda-lime-silica (SLS) glass manufacture. Among the analyses carried out were glass melting including a stages-of-melting study, with XRF, XRD, DSC/TGA and X-ray Micro-CT. From results to date, when compared to a benchmark glass batch containing limestone (CaCO3), as the calcium oxide source, wollastonite maintained faster reaction kinetics which points to lower energy demand during batch reaction processes and consequently, lower melting energies. |
