Solarization of the zeolite production: Calcination of kaolin …
The calcination of kaolin in industry is commonly carried out using rotary kilns and multiple hearth furnaces (MHF) (Jämsä-Jounela et al., 2018).While this process does not produce harmful gases that pollute the environment, it requires a significant amount of energy, often derived from the combustion of fossil fuels such as oil or coal (Tasiopoulou et al., 2023).
