Materials and the Environment

Materials and the Environment: Eco-Informed Material Choice, Second Edition, is the first book devoted solely to the environmental aspects of materials and their selection, production, use and disposal, by one of the world's foremost materials authorities. It explores human dependence on materials and its environmental consequences and provides perspective, background, methods, and data for thinking about and designing with materials to minimize their environmental impact.

Organized into 15 chapters, this new edition looks at the history of our increasing dependence on materials and energy. It explains where materials come from and how they are used in a variety of industries, along with their life cycle and their relationship to energy and carbon. It also examines controls and economic instruments that hinder the use of engineering materials, considers sustainability from a materials perspective, and highlights the importance of low-carbon power and material efficiency. Furthermore, it discusses the mechanical, thermal, and electrical properties of engineering metals, polymers, ceramics, composites, and natural materials in relation to environmental issues. The volume includes new chapters on Materials for Low Carbon Power & and Material Efficiency, all illustrated by in-text examples and expanded exercises. There are also new case studies showing how the methods discussed in the book can be applied to real-world situations.

This book is intended for instructors and students of Engineering, Materials Science and Industrial/Product Design, as well as for materials engineers and product designers who need to consider the environmental implications of materials in their designs.

• Introduces methods and tools for thinking about and designing with materials within the context of their role in products and the environmental consequences
• Contains numerous case studies showing how the methods discussed in the book can be applied to real-world situations
• Includes full-color data sheets for 40 of the most widely used materials, featuring such environmentally relevant information as their annual production and reserves, embodied energy and process energies, carbon footprints, and recycling data

New to this edition:

• New chapter of Case Studies of Eco-audits illustrating the rapid audit method
• New chapter on Materials for Low Carbon Power examines the consequences for materials supply of a major shift from fossil-fuel based power to power from renewables
• New chapter exploring Material Efficiency, or design and management for manufacture to provide the services we need with the least production of materials
• Recent news-clips from the world press  that help place materials issues into a broader context.are incorporated into all chapters
• End-of-chapter exercises have been greatly expanded
• The datasheets of Chapter 15 have been updated and expanded to include natural and man-made fibers

Students of Engineering, Materials Science and Industrial/Product Design; Materials & Industrial Engineers; Product Designers
