The influence of ZSM-5 zeolite and Red Mud in the pyrolysis of plastic wastes has been studied. Both catalysts have been thoroughly characterized; the zeolite shows weak and strong acid sites and great BET surface area (412.0 m 2 g −1), while Red Mud contains lower acidity, with also weak and strong acid sites, meso-macropores and BET surface area of 27.49 …

During alkaline refining of alumina, an alkaline industrial waste residue called red mud is produced. Given its complex composition, large specific surface area, and strong alkalinity, it has been challenging to find a large-scale application for red mud (Lu et al., 2019).The red mud problem has confounded alumina production and alumina plant …

Approximately 1.5–2.0 t red mud is generated as a byproduct during the production of one ton of alumina (Hong et al., 2017). The growth rate of red mud production has drastically increased and it was expected that the total cumulative amount of disposed red mud would exceed three billion tons between 2010 and 2015 (Power et al., 2011).
