“…In this context, several studies have been carried out in the framework of recovering agricultural waste in the production of activated charcoal. These coals are derived from lignocellulosic residues, such as olive kernels [33], apricot kernel shell [34], apricot stones [35], almond shells [36], pistachio shells [37], walnut shells [38], date kernels [39], banana stalks [9], rambutan peels [40], mangosteen peels [41], corncob [42], grape marks [43], coconut shells [44], peanut shells [45], etc. They are used, in turn, in water treatment [36,38,39,43], product purification [30,42], and gas adsorption systems [40,41].…”
