Book excerpt: Metal recycling is a complex business that is becoming increasingly difficult! Recycling started long ago, when people realized that it was more resource- and cost-efficient than just throwing away the resources and starting all over again. In this report, we discuss how to increase metal-recycling rates - and thus resource efficiency - from both quantity and quality viewpoints. The discussion is based on data about recycling input, and the technological infrastructure and worldwide economic realities of recycling. Decision-makers set increasingly ambitious targets for recycling, but far too much valuable metal today is lost because of the imperfect collection of end-of-life (EoL) products, improper practices, or structural deficiencies within the recycling chain, which hinder achieving our goals of high resource efficiency and resource security, and of better recycling rates.

Download or read book Gear Materials Properties and Manufacture written by Joseph R. Davis and published by ASM International. This book was released on 2005 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: All of the critical technical aspects of gear materials technology are addressed in this new reference work. Gear Materials, Properties, and Manufacture is intended for gear metallurgists and materials specialists, manufacturing engineers, lubrication technologists, and analysts concerned with gear failures who seek a better understanding of gear performance and gear life. This volume complements other gear texts that emphasize the design, geometry, and theory of gears. The coverage begins with an overview of the various types of gears used, important gear terminology, applied stresses and strength requirements associated with gears, and lubrication and wear. This is followed by in-depth treatment of metallic (ferrous and nonferrous alloys) and plastic gear materials. Emphasis is on the properties of carburized steels, the material of choice for high-performance power transmission gearing.

This book was released on 2016-06-24 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Utilization of Slag in Civil Infrastructure Construction strives to integrate the theory, research, and practice of slag utilization, including the production and processing of slags. The topics covered include: production and smelting processes for metals; chemical and physical properties of slags; pretreatment and post-treatment technology to enhance slag properties; potential environmental impact; mechanisms of potential expansion; special testing methods and characteristics; slag processing for aggregate and cementitious applications; suitability of slags for use in specific applications; overall properties of materials containing slags; and commercialization and economics. The focus of the book is on slag utilization technology, with a review of the basic properties and an exploration of how its use in the end product will be technically sound, environment-friendly, and economic. - Covers the production, processing, and utilization of a broad range of ferrous, non-ferrous, and non-metallurgical slags - Provides information on applicable methods for a particular slag and its utilization to reduce potential environmental impacts and promote natural resource sustainability - Presents the overall technology of transferring a slag from the waste stream into a useful materials resource - Provides a detailed review of the appropriate utilization of each slag from processing right through to aggregate and cementitious use requirements
Download or read book Trade Competitiveness of the Middle East and North Africa written by Jos R. L pez-C lix and published by World Bank Publications. This book was released on 2010-07-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, four major developments in global economic integration have shaped trade policy and the economic performance of countries within the Middle East and North Africa region: the emergence of global supply chains, the growth of trade in services, the rise of China and India as major international trading powers, and regional integration. These developments, along with the labor and natural resource endowments of particular countries (some are resource-poor but labor-abundant, some resource-rich and labor-abundant, and some resource-rich and labor-importing), have influenced export diversification outcomes across the region. Yet these countries may not be taking full advantage of all of the opportunities the four new trends offer to them. 'Trade Competitiveness of the Middle East and North Africa: Policies for Export Diversification' examines the region's trade policy agendas and their results by focusing on the countries' response to these four key developments in international trade. As the region recovers from the global financial and economic crises, the book identifies reforms that could allow countries to further strengthen global production networks, benefit more from trade in services, better compete in external markets to face the rise of China and India, and reach the full potential of regional integration. If thoroughly implemented, especially by oil exporters, all of these reforms could help boost growth and job creation in the region.
Download or read book Minerals Critical Minerals and the U S Economy written by National Research Council and published by National Academies Press. This book was released on 2008-03-11 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.

Download or read book Kazakhstan Accelerating Economic Diversification written by Kym Anderson and published by Asian Development Bank. This book was released on 2018-08-01 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kazakhstan has the potential to become an economic leader in Central Asia. Relying on oil and gas alone, however, will not produce the long-run level of growth needed to meet this potential. Reforms geared to improve the business climate, enhance competitiveness, and increase private sector participation are essential. This book examines reforms to accelerate economic diversification in the country. This involves not only modernizing and using public resources in agriculture more efficiently to increase productivity, but also transitioning of manufacturing toward high-potential exports to help the country’s industrial development and create employment opportunities. Upgrading innovation of oilfield services and improving transport and logistics are important to increase participation in the global value chains.
