Book Description
This book is a must for individuals and companies that have an interest in developing sustainable technology and systems in the complex 'Web of Metals' on a first principles, technological and economic basis, with a focus to the minerals, metals and product manufacturing industries. In this inter-, intra- and trans-disciplinary book the material/metal cycle will be central, addressing technology as the basis for achieving sustainability within the system of primary mineral and metal producing, and the consumer product material cycles, linked to nature's cycles. The following major topics (not exclusive) are discussed in a detail, which will satisfy company CEO's and students of environment, engineering, economics, and law alike: (i) industrial ecology, (ii) system engineering concepts, (iii) development of future breakthrough technology as well optimization of present technology, (iv) process fundamentals (e.g. thermodynamics, separation physics, transport processes etc.), (v) product manufacture and design (for recycling), (vi) environmental legislation and (vii) technology as a basis for achieving sustainability within our present society. The book discusses contentious issues such as the limits of recycling determined by physics, chemistry, economics and process technology, therefore providing the reader with a fundamental basis to understand and critically discuss the validity of environmental legislation. Furthermore, the 'Web of Metals' (i.e. the dynamic interconnection of metal and material cycles and product systems) will reveal that, if the application of environmental evaluation techniques such as material flow analysis, life cycle assessment etc. are not carried out on a sufficient theoretical basis, technological and economic understanding, analyses could lead to erroneous and in the end environmentally harmful conclusions. The book is illustrated with many industrial examples embracing car and electronic consumer goods manufacturing and recycling, and the production and recycling of all major metals (e.g. steel, aluminium, copper, zinc, lead, magnesium, PGM's and PM's) and to an extent plastics. A complete section of the book is devoted to the recycling of light metals. Numerous colour figures and photos, plant and reactor data as well as software and computer models (running under Matlab's Simulink® and AMPL® as well as tools based on neural net technology (CSenseTM) are provided to give the reader the opportunity to investigate the various topics addressed in this book at various levels of depth and theoretical sophistication, providing a wealth of information, share-data and industrial know-how. Finally, the book philosophically discusses how to harmonize the resource, life and technological cycles depicted by the figure on the cover to make a contribution to the sustainable use of resources and products. * Material and Metal Ecology and the various modelling aspects to quantify this * System modelling of recycling systems with applications in the automotive and consumergoods sector* Metallurgical metal recycling with applications in aluminium, supplemented with various modelling examples from thermodynamics, exergy, neural nets to CFD

Book Description
Solid waste management is a global concern, and landfilling remains the predominant management method in most areas of the world. This book provides a comprehensive view of state-of-the-art methods to manage landfills more sustainably, drawing upon more than two decades of research, design, and operational experiences at operating sites across the world. Sustainable landfills implement one or multiple technologies to control and enhance the degradation of waste materials to realize a multitude of potential benefits during or shortly after the landfill’s operating phase. This book presents detailed approaches in the development, design, operation, and monitoring of sustainable landfills. Case studies showcasing the benefits and challenges of sustainable landfill technologies are also provided to give the reader additional context. The intent of the book is to serve as a reference guide for regulatory personnel, a practical tool for designers and engineers to build on for site-specific applications of sustainable landfill technologies, and a comprehensive resource for researchers who are continuing to explore new and better ways to more sustainably manage waste materials.

Book Description
Solid Waste Landfilling: Concepts, Processes, Technology provides information on technologies that promote stabilization and minimize environmental impacts in landfills. As the main challenges in waste management are the reduction and proper treatment of waste and the appropriate use of waste streams, the book satisfies the needs of a modern landfill, covering waste pre-treatment, in situ treatment, long-term behavior, closure, aftercare, environmental impact and sustainability. It is written for practitioners who need specific information on landfill construction and operation, but is also ideal for those concerned about the possible return of these sites to landscapes and their subsequent uses for future generations. Includes input by international contributors from a vast number of disciplines Provides worldwide approaches and technologies Showcases the interdisciplinary nature of the topic Focuses on sustainability, covering the lifecycle of landfills under the concept of minimizing environmental impact Presents knowledge of the legal framework and economic aspects of landfilling

Book Description
In the metropolitan areas of Japan, coastal landfills have become a practical and main solution for the disposal of municipal solid waste incinerator ash (MSWIA) due to limited inland space. Leachate from the landfilled MSWIA contains many dissolved and suspended substances harmful to the surrounding environment, particularly heavy metals, such as lead, zinc, and cadmium. The mobility assessment of these heavy metals is therefore one of the important environmental issues for the coastal landfill. In this paper, modified batch tests were conducted to investigate the effects of pH and Eh changes on the mobility of heavy metals in both MSWIA and marine clay layer. Based on the speciation of heavy metals by using a sequential extraction method in the leachate-MSWIA and leachate-marine clay systems, heavy metal mobility and availability were discussed with the comparison to large-scale model test results presented by (Kamon et al. "Biochemical Effects on the Long-Term Mobility of Heavy Metals in Marine Clay at Coastal Landfill Sites," J. ASTM Int., Volume 3, 2006), which provides the long-term change in heavy metal concentrations and forms in the coastal MSWIA landfill site. Under the high pH (?11) and low Eh (?-200 mV) condition in the MSWIA-leachate system, Zn, Pb, and Cd were effectively immobilized by the formation of the reducible and oxidizable fractions of Zn and the oxidizable and residual (insoluble) fractions of Pb significantly. However, the potential mobility of Cd was relatively high since the formation of exchangeable compounds was more dominantly contributed to the immobilization. Test results on the speciation of the metals in the marine clay-leachate system accounts well for the evidence that the marine clay acts as the attenuation layer for heavy metals in leachate. These findings strongly support that heavy metal mobility is restricted in the coastal MSWIA landfill due to the formation of stable and insoluble forms under reduced-alkaline condition and the attenuation effect of the marine clay.
