Innovations for Sustainability: Bridging Industrial and Environmental Applications is the second volume in the Nanobioenergy series and presents recent advances in biotechnology aimed at addressing industrial, environmental, agricultural, and sustainability challenges. The book brings together multidisciplinary perspectives covering bioprocess optimization, media engineering, genetic and metabolic engineering, artificial intelligence and machine learning in bioprocess development, microbial metabolites, and the exploitation of endophytic, extremophilic, and marine microorganisms.The volume also emphasizes environmental biotechnology and sustainable resource management through microbial bioremediation, advanced wastewater treatment, phycoremediation, phytoremediation, heavy-metal removal, bio-electrochemical systems, biomethane utilization, and renewable natural gas production. Several chapters demonstrate how biological processes can contribute to pollution control, waste valorization, circular bioeconomy, renewable energy, and environmentally responsible industrial practices.With its integration of biotechnology, microbiology, biochemical engineering, environmental science, artificial intelligence, and renewable-energy technologies, the book provides a useful reference for researchers, academicians, postgraduate students, biotechnology and microbiology professionals, environmental scientists, biochemical engineers, and industry practitioners working toward sustainable technological solutions. The preface specifically describes the volume as being organized into three broad sections: cutting-edge biotechnology innovations; microbial and metabolic products; and environmental biotechnology and sustainability.
