Overuse and misuse of different antibiotics are considered as one of the main causes of antibiotics accumulation in the environment, most commonly used antibiotics are semimetabolized and excreted by humans to the environment. Studies reported that antibiotic usage exceeds 100,000 tons per year, and this amount may be shocking. However, in fact, the persistence of antibiotic compounds may be more dangerous than the used amount, so it is necessary to develop new methods for elimination of these new pollutants from the environment, especially from water. In this paper, we highlight new and more efficient methods used for removing antibiotic residues (AR) and antibiotic resistance genes (ARGs). The new techniques are Fe3O4/red mud nanoparticles, 3D hierarchical porous-structured biochar aerogels, calcined layered double hydroxides, co-doped UiO-66 nanoparticles, Cu@TiO2 hybrids, bioelectrochemical systems, and aerobic granulation process. Most of these methods showed good performance in removing AR and ARGs that ranged from 85% to 95%. These percentages are consider very efficient compared with traditional wastewater treatment methods.
