Researcher Aydin Hassani from Faculty of Engineering, Near East University have actively contributed to a comprehensive review focusing on sustainable and cost-effective wastewater treatment technologies. The study examines recent developments and applications of biochars and green nanoparticles (NPs) derived from agricultural waste through eco-friendly routes for efficiently removing refractory pollutants from water and wastewater.
The review underscores the significance of green catalysts, particularly biochars and NPs, which are derived from agricultural waste as feedstocks. Biochar, renowned for its low cost, environmental friendliness, large surface area, and porous structure, emerges as a valuable material for advanced oxidation processes (AOPs) in removing refractory organic pollutants. The discussion explores the mechanisms behind the catalytic removal of contaminants, showcasing the potential of these materials for treating agricultural wastewater, municipal wastewater, and industrial wastewater at the lab scale.
Key findings from the review highlight the importance of biochar’s characteristics in AOPs, the influence of pyrolysis temperature on its structure and performance, and the necessity of addressing real-world challenges for on-site implementation. The study recognizes the potential leakage of nano-sized catalysts into the environment, emphasizing the need for improved recovery rates to prevent environmental pollution.
The review identifies critical gaps in current knowledge and suggests avenues for future research. These include exploring the environmental impact of tailoring processes, addressing the catalytic removal of mixed and multi-polluted systems, evaluating the stability and production cost of catalysts for practical applications, conducting life cycle assessments (LCA) for environmental sustainability, and emphasizing cost-effective mass production of green catalysts.
By providing a comprehensive overview of green catalyst synthesis and its application in wastewater treatment, this research offers valuable insights to the field. The recommendations for future research directions underscore the importance of addressing environmental concerns, optimizing catalyst performance, and facilitating large-scale implementation of sustainable wastewater treatment technologies.
