This handbook discusses the latest developments in biorefinery technologies for waste-to-energy conversion. The growing global population and the accompanying increase in consumption and waste production make it urgent to find the best possible use of our resources. A sustainable waste management under the biorefinery concept has great potential to support a sustainable circular economy and green energy production.This handbook is divided into four parts. First, the reader is introduced to the fundamentals and recent trends of waste-to-energy technologies. The second part describes in detail the current status, challenges, and potential of the different feedstocks used for waste-to-energy conversion. Here, municipal solid waste, sewage sludge, oils and greases generated during food preparation, industrial wastewaters, and agricultural wastes, to name a few, are introduced.  In the third part, numerous waste-to-energy technologies are discussed in detail, including anaerobic digestion, composting, gasification, plasma technology, thermal cracking, and others. Advantages and optimization potentials of these technologies for efficient residue management, quality and yield are highlighted.Finally, the handbook discusses social, environmental and economic aspects of waste-to-energy biorefinery technologies. Readers will learn more about the major bottlenecks and solutions in bioenergy commercialization, the logistics of biomass supply and the carbon footprint of waste biorefineries. The ideas and technologies presented in this book contribute to the UN Sustainable Development Goal (SDG) of "e;Affordable and Clean Energy"e;.This book is a useful reference for postgraduate students and researchers interested in biorefinery and biofuel technologies, both in academia- and commercial laboratories. Early career scientists can use it to fast track into the field. Advanced scientists will find it helpful in gaining a broader overview of the field beyond their area of specialization.

This book presents information on the origin and distribution of microplastics, evaluates the methods of their detection, documents their interactions with natural systems, and analyzes the current understanding of their management. Owing to the size, varied compositions, pathways of transport, accumulation and myriad processes of interactions with ecosystems, the microplastics pose severe threats to ecosystem services and natural environmental systems. Therefore, the environmental challenges that microplastics present and the strategies to mitigate their harmful impacts are of great importance to the scientific community, and only a few publications exist that collate this information in a single resource. The book aims to be a comprehensive resource for students, professionals and practitioners of environmental studies on microplastics and how to better understand the threats they pose and the practices to manage them. 

This book presents the coupled Thermo-Hydro-Mechanical-Chemical (THMC) processes in fractured rocks at varying scales from single fractures to fracture networks. It also discussed the implication and potential application of the advanced understanding of coupled THMC processes in fractured rocks for geotechnical and geo-energy engineering.
