Waste-to-wealth: biowaste valorization into valuable (nano)catalysts

One of the biggest current challenges is environmental pollution which increasingly develops with passing time and causes seriousand irreparable damage to the ecosystem. Industrial wastes have become a great dilemma for developing, modern and postmoderncountries as a result of technological activities. Furthermore, unfavourable and improper disposal of decomposable biowaste leads tomajor environmental problems, including water pollution, odors, dust, ammonia and methane emission which can affect greenhousegas emissions [1,2]. Regarding these issues, attention to biowaste valorization into valuable materials have been on the rise; in orderto avoid the as-mentioned problems and put a step forward to safer industrial productions. One of the fields for utilization of biowastesis preparation of (nano)catalysts. Till now, there had been a wide progress in preparation of (nano)catalysts based on biopolymers ormaterials derived from residue of fruits, nuts, animals etc. as valuable biowastes [3,4]. The present work discuses extensively andcomprehensively the biowastes used to prepare the new generation of safer and cheaper catalytic nanosystems.
