Waste Management and Resource Recycling in the Developing World provides a unique perspective on the state of waste management and resource recycling in the developing world, offering practical solutions based on innovative tools and technologies, along with examples and case studies. The book is organized by waste type, including electronic, industrial and biomedical/hazardous, with each section covering advanced techniques, such as remote sensing and GIS, as well as socioeconomic factors, transnational transport and policy implications. Waste managers, environmental scientists, sustainability practitioners, and engineers will find this a valuable resource for addressing the challenges of waste management in the developing world. There is high potential for waste management to produce energy and value-added products. Sustainable waste management based on a circular economy not only improves sanitation, it also provides economic and environmental benefits. In addition to waste minimization, waste-to-economy and waste-to-energy have become integral parts of waste management practices. A proper waste management strategy not only leads to reduction in environmental pollution but also moves toward generating sufficient energy for improving environmental sustainability in coming decades.

The writing of this book was largely motivated by the ongoing unprecedented world-wide restructuring of the power industry. This move away from the traditional monopolies and toward greater competition, in the form of increased numbers of independent power producers and an unbundling of the main services that were until now provided by the utilities, has been building up for over a decade. This change was driven by the large disparities in electricity tariffs across regions, by technological developments that make it possible for small producers to compete with large ones, and by a widely held belief that competition will be beneficial in a broad sense. All of this together with the political will to push through the necessary legislative reforms has created a climate conducive to restructuring in the electric power industry. Consequently, since the beginning of this decade dramatic changes have taken place in an ever-increasing list of nations, from the pioneering moves in the United Kingdom, Chile and Scandinavia, to today's highly fluid power industry throughout North and South America, as well as in the European Community. The drive to restructure and take advantage of the potential economic benefits has, in our view, forced the industry to take actions and make choices at a hurried pace, without the usual deliberation and thorough analysis of possible implications. We must admit that to speak of "the industry" at this juncture is perhaps disingenuous, even misleading.

This book is a collection of chapters concerning the use of biomass for the sustainable production of energy and chemicals-an important goal that will help decrease the production of greenhouse gases to help mitigate global warming, provide energy security in the face of dwindling petroleum reserves, improve balance of payment problems and spur local economic development. Clearly there are ways to save energy that need to be encouraged more. These include more use of energy sources such as, among others, manure in anaerobic digesters, waste wood in forests as fuel or feedstock for cellulosic ethanol, and conservation reserve program (CRP) land crops that are presently unused in the US. The use of biofuels is not new; Rudolf Diesel used peanut oil as fuel in the ?rst engines he developed (Chap. 8), and ethanol was used in the early 1900s in the US as automobile fuel [Songstad et al. (2009) Historical perspective of biofuels: learning from the past to rediscover the future. In Vitro Cell Dev Biol Plant 45:189-192). Brazil now produces enough sugar cane ethanol to make up about 50% of its transportation fuel needs (Chap. 4). The next big thing will be cellulosic ethanol. At present, there is also the use of Miscanthus x giganteous as fuel for power plants in the UK (Chap. 2), bagasse (sugar cane waste) to power sugar cane mills (Chap. 4), and waste wood and sawdust to power sawmills (Chap. 7).

Optical Microscanners and Microspectrometers using Thermal Bimorph Actuators shows how to design and fabricate optical microsystems using innovative technologies and and original architectures. A barcode scanner, laser projection mirror and a microspectrometer are explained in detail, starting from the system conception, discussing simulations, choice of cleanroom technologies, design, fabrication, device test, packaging all the way to the system assembly.

An advanced microscanning device capable of one- and two-dimensional scanning can be integrated in a compact barcode scanning system composed of a laser diode and adapted optics. The original design of the microscanner combines efficiently the miniaturized thermal mechanical actuator and the reflecting mirror, providing a one-dimensional scanning or an unique combination of two movements, depending on the geometry. The simplicity of the device makes it a competitive component.

The authors rethink the design of a miniaturized optical device and find a compact solution for a microspectrometer, based on a tunable filter and a single pixel detector. A porous silicon technology combines efficiently the optical filter function with a thermal mechanical actuator on chip. The methodology for design and process calibration are discussed in detail. The device is the core component of an infrared gas spectrometer.

The first comprehensive monograph in blast cleaning technology, this book provides a comprehensive review of the technology, with an emphasis on practical applications. The author first systematically and critically reviews the theory behind the technology. Next you ll learn about the state of current blast cleaning, surface quality aspects, and the effects of blast cleaning on the performance of applied coatings. You ll also discover many of today 's cutting-edge applications, including micro-machining, polishing, maintenance, and surface preparation for coating applications. Finally, the author describes recent advanced applications in the machining industry, including blast cleaning-assisted laser milling.

Failures of many mechanical components in service result from fatigue. The cracks which grow may either originate from some pre-existing macroscopic defect, or, if the component is of high integrity but highly stressed, a region of localized stress concentration. In turn, such concentrators may be caused by some minute defect, such as a tiny inclusion, or inadvertent machining damage. Another source of surface damage which may exist between notionally 'bonded' components is associated with minute relative motion along the interface, brought about usually be cyclic tangential loading. Such fretting damage is quite insidious, and may lead to many kinds of problems such as wear, but it is its influence on the promotion of embryo cracks with which we are concerned here. When the presence of fretting is associated with decreased fatigue performance the effect is known as fretting fatigue. Fretting fatigue is a subject drawing equally on materials science and applied mechanics, but it is the intention in this book to concentrate attention entirely on the latter aspects, in a search for the quantification of the influence of fretting on both crack nucleation and propagation. There have been very few previous texts in this area, and the present volume seeks to cover five principal areas; (a) The modelling of contact problems including partial slip under tangentialloading, which produces the surface damage. (b) The modelling of short cracks by rigorous methods which deal effectively with steep stress gradients, kinking and closure. (c) The experimental simulation of fretting fatigue.

The main objectives of the Ccmnunity's energy policy consist of securing a sufficient energy supply for the present and future demand of its Member States and in reducing the Community's dependence on imported energy through the more rational use of energy and a broader diversifi cation of supply. This requires a full set of common efforts at all levels, including energy research and development. In the framework of its strategy for scientific and technological research the Commission of the European Ccmnunities has launched several R & D progranunes in the field of energy. Theses progranunes are: inplemented either directly in its Joint Research Centre or by concluding contracts with research institutions in the EC Member countries. One of the most inportant short and medil.UR term objectives of the present four-year Energy R & D Progranune (1979 - 1983) approved by the Council of Ministers on 13 September 1979 aims at fostering energy conservation technologies in the three main energy consl.Uning sectors: danestic, industry and transport. In the European Carmunity more than 35% of the energy is conslB'IIed in industry. About 23% of the inported oil is used in this sector. Two thirds of this energy are used for heating purposes. Consequently, there is a high potential for residuary heat recovery. In order to enhance rational use of energy and energy conservation in the Member States of the Ccmnunity, it is necessary, anong other things, to promote the development of combustion and energy recovery techniques."

This book is ideal for both device engineers as well as circuit system designers, and highlights the importance of co-design across design hierarchies when trying to optimize system performance (in this case, energy-efficiency). The book will also appeal to researchers and engineers focused on semiconductor, integrated circuits, and energy efficient electronics.

Roelof A. A. Oldeman Tropical hardwoods are one of the essential cogs in the complex socio-economic machinery keeping alive an ever-increasing humanity with steadily rising claims upon a finite-resource environment. Their position in this context at first sight seems to be analogous to that of other commodities, such as rubber, metals, mineral oil, tropical fruits and many more. Looking closer, however, tropical hardwoods occupy a special place. Their vast majority, unlike tropical crops, still comes forth from natural forests being exploited by man. This exploitation straight from the natural resource is something they have in common with oil and metals, but the fact that they grow in living systems places them closer to crops. Natural forest ecosystems are not renewable. Timber producing trees, however, can be made into a renewable resource on condition that ways and means are found to cultivate them as a crop. be understood as a socio-economic The tropical hardwood situation can best chain, with the resource base at one end, the consumer community at the other and everything that has to do with the market in the middle. Now, at the resource side, the economics of tropical hardwood extraction barely got out of the primeval ways of wood-gathering by hand and by axe, which were still predominant in the nineteen-forties. There, the offer of natural products was so immense and so near to hand that no care had to be taken of the resource.

The advent of low temperature superconductors in the early 1960's converted what had been a laboratory curiosity with very limited possibilities to a prac tical means of fabricating electrical components and devices with lossless con ductors. Using liquid helium as a coolant, the successful construction and operation of high field strength magnet systems, alternators, motors and trans mission lines was announced. These developments ushered in the era of what may be termed cryogenic power engineering and a decade later successful oper ating systems could be found such as the 5 T saddle magnet designed and built in the United States by the Argonne National Laboratory and installed on an experimental power generating facility at the High Temperature Institute in Moscow, Russia. The field of digital computers provided an incentive of a quite different kind to operate at cryogenic temperatures. In this case, the objective was to ob tain higher switching speeds than are possible at ambient temperatures with the critical issue being the operating characteristics of semiconductor switches under cryogenic conditions. By 1980, cryogenic electronics was established as another branch of electric engineering."

China's rapid economic growth in the recent decades has produced an unprecedented energy vulnerability that could threaten the sustainability of its economic development, a linchpin to social stability and ultimately the regime legitimacy of the Chinese Communist Party (CCP) as well as the foundation for China's rising power aspirations. What is the Chinese perception of the energy security and challenges, how has the Chinese government responded to the challenges? What are the international implications of China's search for energy security? This collection of contributions by leading scholars seeks answers to these extremely important questions. The book is divided into three parts. Part I presents an overview of China's sense of energy security and its strategic responses. Part II examines China's energy policy-making processes, the efforts to reform and reorganize the energy sector and reset policy priorities Part III focuses on the international implications of China's search for energy security. This book consists of articles published in the Journal of Contemporary China.

We are very pleased to be asked to co-author this book for a variety of reasons, one of which was that it gave us further opportunity to work together. The scope proposed was very wide with the only significant proviso being that the book should be in a mongraph-style and not a teaching text. This require ment has given us the opportunity to compile a wide range of relevant material relating to present-day knowledge and application in power system reliability. As many readers will be aware, we have collaborated in many ways over a relatively long period and have co-authored two other books on reliability evaluation. Both of these previous books were structured as teaching texts. This present book is not a discourse on "how to do reliability evaluation" but a discussion on "why it should be done and what can be done and achieved" and as such does not replace or conflict with the previous books. The three books are complementary and each enhances the others. The material contained in this book is not specifically original since it is based on information which we have published in other forms either jointly or as co authors with various other people, particularly our many research students. We sincerely acknowledge the important contributions made by all these students and colleagues. There are too many to mention individually in this preface but their names appear frequently in the references at the end of each chapter."
