Thermally Activated Construction Waste as an Efficient Adsorbent for Free Fatty Acid Removal from Waste Cooking Oil
This study aimed to evaluate the reduction of free fatty acids (FFAs) in waste cooking oil (WCO) using calcined concrete, brick, and ceramic tile residues as adsorbents. Concrete, brick, and ceramic tile residues were collected, ground (590–297 μm), and calcined at 850 °C. Characterization using SEM-EDS, FTIR, XRD, and...
