Green Engineering and Sustainable Technology

“Sustainability is no longer about doing less harm. It’s about doing more good.” - Jochen Zeitz “Progress is impossible without change, and those who cannot change their minds cannot change anything." - George Bernard Shaw The growing rate of industrialization fosters environmental challenges, prompting them to think of greener, safer, and more sustainable alternatives. “Green Engineering and Sustainable Technology” focuses on green engineering practices that provide innovative solutions to existing problems and open up new processes and products that uphold sustainability. The main goal is to bridge the gap between green engineering concepts and practical applications by providing insights into how green principles developed into sustainable technology in industries to promote a circular economy. Following green metrics along with technological advancements that measure sustainability helps to reduce the ecological footprint. These metrics help the organization assess the environmental impacts of its process in terms of energy consumption, carbon emissions, and waste generation to make strategic decisions for eco-friendly manufacturing. The green solvents proposed here play a major role in green engineering and sustainable technology in reducing environmental impact with safety improvement and increased process efficiency. Solvents such as ionic liquids, deep eutectic solvents, and terpenes minimize the emissions with tunable solvation and improve reaction efficiency. Another chapter revealed the need for process intensification to enhance production efficiency through the synergetic effects of integration addressing environmental regulations and sustainability goals. All the integrated techniques in the book delve into groundbreaking developments in environmentally and economically advantageous sustainable technology. Nanoemulsion addressed in the chapter discusses the advantages of emulsification in the food and drug industry and its sustainability in industrial applications. In continuation, techno-economic analysis is addressed here for the economic feasibility, investment decision-making, technology optimization for scale-up, and the green technology advancement for commercialization of any product in the market analysis. In addition, life cycle analysis is needed for waste management, environmental evaluation, uncertainty, sensitivity analysis, and hotspot identification. Both these chapters have a critical role in green engineering and sustainability technology development in providing a framework for supporting the transition to a green economy and attaining sustainability goals. Industrial sustainable fermentation for acids, enzymes, and secondary metabolites production focuses on waste minimization for environmental sustainability. Sustainable fermentation utilizing renewable sources shift industries towards more sustainable production of biofuels, biochemicals, etc., Moreover, green electrolytes are designed to enhance the safety of engines, particularly in the upcoming field of electric vehicles reduce pollution during production, usage, and disposal. This sustainable energy system supports fuel economy and increases the demand for green electrolytes in the electronic field and electric vehicle manufacturing. We hope this book will inspire engineers, researchers, and students to apply green engineering principles in various fields such as biotechnology, chemical, civil, computer, environmental, and material science, who think beyond conventional practices and seek technologically advanced solutions.
