Recent Developments in the Field of Carbon Fibers
Carbon fibres are lightweight, chemically stable materials with high mechanical strength, and have state-of-the-art applications in aerospace, marine, construction and automotive sectors. The demand for carbon fibre?based components is expected to grow dramatically with expanding opportunities for lightweight metals and composites. Although this field has achieved a high level of maturity, nanoscale developments in carbon fibres have seen dramatic improvements in the functions of conventional biomaterials and composites. This book reveals several new developments in the field to enhance characteristics of carbon fibres and their composites, novel applications for tissue engineering, biological scaffoldings and implants, recycling and reuse of end-of-life CFRP and manufacturing waste and other issues of concern in the field of carbon fibres.
Advanced Research in Technologies, Information, Innovation and Sustainability
This book constitutes the refereed proceedings of the First International Conference on Advanced Research in Technologies, Information, Innovation and Sustainability, ARTIIS 2021, held in La Libertad, Ecuador, in November 2021. The 53 full papers and 2 short contributions were carefully reviewed and selected from 155 submissions. The volume covers a variety of topics, such as computer systems organization, software engineering, information storage and retrieval, computing methodologies, artificial intelligence, and others. The papers are logically organized in the following thematic blocks: Computing Solutions; Data Intelligence; Ethics, Security, and Privacy; Sustainability.
Thermoset Composites
Characterization, design, specific properties and applications of thermoset composites are reported. These composites are presently in high demand because they can be shaped into many-sided segments and structures, and can have a great variety of densities and special physical and mechanical properties. The research reported includes: Energy absorption of fiber reinforced composites; automotive crashworthiness; lignocellulosic composites; hybrid bast fiber reinforced composites; nano-carbon/polymer composites; electromagnetic shielding; structural mechanical applications; electromagnetic field emission applications, conductive composites; epoxy composites for structural purposes; tribological performance of polymeric composites.

Environmental Management of Waste Electrical and Electronic Equipment
Environmental Management of Waste Electrical and Electronic Equipment illustrates the socioeconomic, technical and environmental perspectives of WEEE, allowing for a better understanding on how to manage this rapidly growing waste stream. The book addresses discharge of WEEE into ecosystems, occupational exposure to hazardous components of WEEE, and loss of recoverable resources, bridging the gap between community and waste management. By providing in-depth analysis and step-by-step descriptions of environmental strategies and procedures for managing electrical and electronic waste, this book is a valuable resource for environmental scientists, environmental engineers, and waste management professionals to achieve sustainability in WEEE. - Presents the latest knowledge on the origin, identification and adverse effects of WEEE on humans and ecosystems - Offers up-to-date analysis on environmental management tools, such as LCA, health risk, legalization, and policies for sustainable solutions for Waste Electrical and Electronic Equipment (WEEE) - Includes details and analysis of the novel approaches proposed in recent years for resource recovery from WEEE
E-Waste in Transition
E-waste management is a serious challenge across developed, transition, and developing countries because of the consumer society and the globalization process. E-waste is a fast-growing waste stream which needs more attention of international organizations, governments, and local authorities in order to improve the current waste management practices. The book reveals the pollution side of this waste stream with critical implications on the environment and public health, and also it points out the resource side which must be further developed under the circular economy framework with respect to safety regulations. In this context, complicated patterns at the global scale emerge under legal and illegal e-waste trades. The linkages between developed and developing countries and key issues of e-waste management sector are further examined in the book.

Silver Hydrometallurgy
The main impression of this book is to draw attention to the most advance technologies in silver recovery and recycling from various sources. The state-of-the-art in silver recovery from different sources by hydrometallurgical and bio-metallurgical processing, and varieties of leaching, cementing, reducing agents, peeling, electro-coagulants, adsorbents, electro-dialysis, solvent extraction, ion exchange resins and bio-sorbents are highlighted in this book. It is shown that the major economic driver for the recycling of depleted sources is for the recovery of silver. In order to develop a nature-friendly technique for the recovery of silver from diverse sources, a critical comparison of existing technologies is analysed for both economic viability and environmental impact were made in this amendment, and silver ion toxicity is highlighted in this book. This book comprises four chapters, each of which is further divided into sections and subsections for the proper convenience and understanding of the work, though extensive work has been reported on silver hydrometallurgy.
Management, Recycling and Reuse of Waste Composites
This authoritative reference work provides a comprehensive review of the management, recycling and reuse of waste composites. These are issues which are of increasing importance due to the growing use of composites in many industries, increasingly strict legislation and concerns about disposal of composites by landfill or incineration.Part one discusses the management of waste composites and includes an introduction to composites recycling and a chapter on EU legislation for recycling waste composites. Part two reviews thermal technologies for recycling waste composites with chapters on pyrolysis, catalytic transformation, thermal treatments for energy recovery and fluidized bed pyrolysis. P...
WEEE Recycling
WEEE Recycling: Research, Development, and Policies covers policies, research, development, and challenges in recycling of waste electrical and electronic equipment (WEEE). The book introduces WEEE management and then covers the environmental, economic, and societal applications of e-waste recycling, focusing on the technical challenges to designing efficient and sustainable recycling processes—including physical separation, pyrometallurgical, and hydrometallurgical processes. The development of processes for recovering strategic and critical metals from urban mining is a priority for many countries, especially those having few available ores mining. - Describes the two metallurgical processes—hydro- and pyro-metallurgy—and their application in recycling of metals - Provides a life cycle analysis in the WEEE recycling of metals - Outlines how to determine economic parameters in the recycling of waste metals - Discusses the socio economic and environmental implication of metal recycling
