Life cycle assessment (LCA) is used to evaluate the environmental impacts of textile products, from raw material extraction, through fibre processing, textile manufacture, distribution and use, to disposal or recycling. LCA is an important tool for the research and development process, product and process design, and labelling of textiles and clothing. Handbook of Life Cycle Assessment (LCA) of Textiles and Clothing systematically covers the LCA process with comprehensive examples and case studies. Part one of the book covers key indicators and processes in LCA, from carbon and ecological footprints to disposal, re-use and recycling. Part two then discusses a broad range of LCA applications in the textiles and clothing industry. - Covers the LCA process and its key indicators, including carbon and ecological footprints, disposal, re-use and recycling - Examines the key developments of LCA in the textile and clothing industries - Provides a wide range of case studies and examples of LCA applications in the textile and clothing industries
"Red Silk is a history of China’s Yangzi Delta silk industry during the wars, crises, and revolutions of the mid-twentieth century. Based on extensive research in Chinese archives and focused on the 1950s, the book compares two very different groups of silk workers and their experiences in the revolution. Male silk weavers in Shanghai factories enjoyed close ties to the Communist party-state and benefited greatly from socialist policies after 1949. In contrast, workers in silk thread mills, or filatures, were mostly young women who lacked powerful organizations or ties to the revolutionary regime. For many filature workers, working conditions changed little after 1949 and politicized production campaigns added a new burden within the brutal and oppressive factory regime in place since the nineteenth century. Both groups of workers and their employers had to adapt to rapidly changing circumstances. Their actions—protests, petitions, bribery, tax evasion—compelled the party-state to adjust its policies, producing new challenges. The results, though initially positive for many, were ultimately disastrous. By the end of the 1950s, there was widespread conflict and deprivation among silk workers and, despite its impressive recovery under Communist rule, the industry faced a crisis worse than war and revolution."
Wholesale marketing systems for fruit, vegetables and other fresh foodstuffs, such as livestock and fish, are often inadequate. They neither maximize benefits to producers, nor to consumers. This manual has been compiled to provide a systematic methodology based on the sequence of steps normally adopted in the development process. The manual should be of practical value, both to senior professionals and to technicians, in undertaking marketing and engineering surveys, in the preparation of feasibility studies and master plans, and in formulating proposals for the provision of physical facilities.
This book offers a detailed understanding of the principles, procedures, equipment, and operation of selected technologies used to manufacture and evaluate intelligent multifunctional textiles and apparel goods. Leading experts from different domains of polymers, fiber production, nanotechnology, and textile chemical finishing address the entire production process by delving into crucial concepts and topics such as the development, characterization, and potential applications of functional materials. Textiles for Functional Applications is an excellent resource for researchers, designers, and academics who want to learn more about designing feasible functional textiles.
Silk is increasingly being used as a biomaterial for tissue engineering applications, as well as sutures, due to its unique mechanical and chemical properties. Silk Biomaterials for Tissue Engineering and Regenerative Medicine discusses the properties of silk that make it useful for medical purposes and its applications in this area. Part one introduces silk biomaterials, discussing their fundamentals and how they are processed, and considering different types of silk biomaterials. Part two focuses on the properties and behavior of silk biomaterials and the implications of this for their applications in biomedicine. These chapters focus on topics including biodegradation, bio-response to silk sericin, and capillary growth behavior in porous silk films. Finally, part three discusses the applications of silk biomaterials for tissue engineering, regenerative medicine, and biomedicine, with chapters on the use of silk biomaterials for vertebral, dental, dermal, and cardiac tissue engineering. Silk Biomaterials for Tissue Engineering and Regenerative Medicine is an important resource for materials and tissue engineering scientists, R&D departments in industry and academia, and academics with an interest in the fields of biomaterials and tissue engineering. - Discusses the properties and applications of silk for medical purposes - Considers pharmaceutical and cosmeceutical applications
Natural Fiber-Reinforced Biodegradable and Bioresorbable Polymer Composites focuses on key areas of fundamental research and applications of biocomposites. Several key elements that affect the usage of these composites in real-life applications are discussed. There will be a comprehensive review on the different kinds of biocomposites at the beginning of the book, then the different types of natural fibers, bio-polymers, and green nanoparticle biocomposites are discussed as well as their potential for future development and use in engineering biomedical and domestic products. Recently mankind has realized that unless the environment is protected, he himself will be threatened by the over consumption of natural resources as well as a substantial reduction in the amount of fresh air produced in the world. Conservation of forests and the optimal utilization of agricultural and other renewable resources like solar, wind, and tidal energy, have become important topics worldwide. With such concern, the use of renewable resources—such as plant and animal-based, fiber-reinforced polymeric composites—are now becoming an important design criterion for designing and manufacturing components for a broad range of different industrial products. Research on biodegradable polymeric composites can contribute, to some extent, to a much greener and safer environment. For example, in the biomedical and bioengineering fields, the use of natural fiber mixed with biodegradable and bioresorbable polymers can produce joint and bone fixtures to alleviate pain in patients. - Includes comprehensive information about the sources, properties, and biodegradability of natural fibers - Discusses failure mechanisms and modeling of natural fibers composites - Analyzes the effectiveness of using natural materials for enhancing mechanical, thermal, and biodegradable properties
This publication sets out a detailed systems analysis approach to the small and medium agro-food industries sector in Latin America and the Caribbean region, in order to promote food safety and quality as well as enterprise productivity and competitiveness. The issues are discussed from food engineering and technology perspectives, in light of the complex issues faced by small food industries in the current trading system.
One of the main objectives of the Agreement on Agriculture (AoA) negotiated under the Uruguay Round is to improve the access of developing countries to foreign markets. Constraints in the domestic supply chains of many countries, along with weak marketing support and trade facilitation services, have prevented them, however, from exploiting the opportunities provided by the AoA and by other agreements to improve market access. The aim of this guide is to inform policy analysts on issues that should be considered while developing policies and measures to break the main processing and marketing constraints that prevent their countries from fully exploiting their agrifood export potential.
