Advanced and Emerging Technologies for Resource Recovery from Wastes
This book introduces advanced or emerging technologies for conversion of wastes into a variety of high-value chemicals and materials. Energy and resources can be recovered from various residential, industrial and commercial wastes, such as municipal wastewater and sludge, e-waste, waste plastics and resins, crop residues, forestry residues and lignin. Advanced waste-to-resource and energy technologies like pyrolysis, hydrothermal liquefaction, fractionation, de-polymerization, gasification and carbonization are also introduced. The book serves as an essential guide to dealing with various types of wastes and the methods of disposal, recovery, recycling and re-use. As such it is a valuable resource for a wide readership, including graduate students, academic researchers, industrial researchers and practitioners in chemical engineering, waste management, waste to energy and resources conversion and biorefinery.
Green Biorefinery Solutions
This book delves into the innovative concept of biorefineries as a sustainable approach for managing biodegradable waste and producing valuable resources. It highlights the pressing need to address environmental challenges, such as waste accumulation and resource depletion while meeting the increasing demand for renewable energy and bio-based products. The book introduces the concept of biorefineries, which are analogous to conventional oil refineries but focus on converting biomass and biodegradable waste into a range of high-value products. These products include biofuels, biochemicals, bioplastics, biofertilizers, and other materials that can replace fossil-derived equivalents. The author explores various technological pathways and processes involved in efficiently transforming different types of biodegradable waste, such as agricultural residues, food waste, and organic byproducts, into usable resources. Readers are guided through the principles of biorefinery design, integration of various unit operations, and the optimization of conversion processes to achieve maximum resource utilization and minimal environmental impact. The book emphasizes the importance of circular economy concepts, where waste is considered a valuable input rather than a burden. It also discusses the economic, social, and environmental benefits of adopting biorefinery solutions in different sectors, from agriculture to industry. The book is a valuable resource for researchers, policymakers, industry professionals, and students interested in exploring innovative approaches to waste management, resource recovery, and the transition towards a more sustainable and circular bioeconomy. By highlighting the transformative potential of biorefineries, the book contributes to the ongoing dialogue on creating a more environmentally conscious and resource-efficient future.

This book, besides discussing challenges and opportunities, will reveal the microbe-metal interactions and strategies for e-waste remediation in different ecosystems. It will unveil the recent biotechnological advancement and microbiological approach to sustainable biorecycling of e-waste such as bioleaching for heavy metal extraction, valorization of precious metal, biodegradation of e-plastic, the role of the diverse microbial community in e-waste remediation, genetically engineered microbes for e-waste management, the importance of microbial exopolysaccharides in metal biosorption, next-generation technologies, omics-based technologies etc. It also holds the promise to discuss the conservation, utilization and cataloging indigenous microbes in e-waste-polluted niches and promising hybrid technology for sustainable e-waste management. Revolution in the area of information technology and communication is constantly evolving due to scientific research and development. Concurrently, the production of new electrical and electronic equipment also thus uplifting in this era of revolution. These technological advancements certainly have problematic consequences which is the rise of huge amounts of electronic obsoletes or electronic waste (e-waste). Improper management of both hazardous and nonhazardous substances of e-waste led to a major concern in our digital society and environment. Therefore, a sustainable approach including microbial candidates to tackle e-waste is the need of the hour. Nevertheless, the continuous demand for new-generation gadgets and electronics set this high-tech evolution to a new frontier in the last few years. With this continuing trend of technological development, e-waste is expanding exponentially worldwide. In the year of 2019, the worldwide generation of e-waste was approximately 53.6 Mt, of which only about 17.4% of e-waste was collected and recycled, and the other 82.6% was not even documented. E-waste contains various heterogeneous waste complexes such as metals (60%), blends of many polymers (30%) and halogenated compounds, radioactive elements and other pollutants (10%), respectively. The sustainable, efficient, and economic management of e-waste is thus, a challenging task today and in the coming decades. Conventional techniques such as the use of chemicals, incineration and informal ways of e-waste dismantling trigger serious health risks and contamination to the human population and environment, respectively due to the liberation of toxic and hazardous substances from the waste. In this context, bio-candidates especially microorganisms could be sharp-edged biological recycling tools to manage e-waste sustainably. As microbes are omnipresent and diverse in their physiology and functional aspects, they offer a wide range of bioremediation.
