Winner of the International Solid Waste Association's 2014 Publication Award, Handbook of Recycling is an authoritative review of the current state-of-the-art of recycling, reuse and reclamation processes commonly implemented today and how they interact with one another. The book addresses several material flows, including iron, steel, aluminum and other metals, pulp and paper, plastics, glass, construction materials, industrial by-products, and more. It also details various recycling technologies as well as recovery and collection techniques. To completely round out the picture of recycling, the book considers policy and economic implications, including the impact of recycling on energy use, sustainable development, and the environment. With contemporary recycling literature scattered across disparate, unconnected articles, this book is a crucial aid to students and researchers in a range of disciplines, from materials and environmental science to public policy studies. Portrays recent and emerging technologies in metal recycling, by-product utilization and management of post-consumer waste Uses life cycle analysis to show how to reclaim valuable resources from mineral and metallurgical wastes Uses examples from current professional and industrial practice, with policy and economic implications
The concept of a circular economy in the construction sector captures global material flow through product design, inverse logistics, innovation and collaborations. The circulation of the economy takes into consideration global population influence, which affects the economy through a variety of construction product flows in particular. The increase in consumers means increasing product and services which participate in different waste streams. The emerging sustainable development in the construction industry requires the recycling of waste materials to reduce the negative environmental impact of construction activities. Accumulation and management of construction wastes is also becoming a major environmental and economical concern in many developing countries. Huge volumes of waste generated end up piled on landfill sites or illegally dumped, posing serious health and ecological problems. In the construction industry, recycling of waste concrete, masonry, cement, gypsum, to mention but a few, has become an important aspect due to the continued increase of construction wastes and depletion of natural aggregates. Why not establish a business system that is specifically designed to do much more value addition to the construction wastes and develop products which are not only in demand locally but internationally, to encourage exports for maximum financial gain. This book aims to analyze the current business model in the construction sector and the current legislation concerning waste management. It also highlights efforts required in order to refine the recycling methods in favor of a circular economy in the constuction industry. In support of a transition to a low carbon economy, different types of materials which can be produced from the construction wastes are indicated including processes which are used to obtain the final products. The market demand including penetration of the resulting products are given extensively. Policies and regulations to govern these undertakings are highlighted also. The municipalities will learn to redirect the local construction industries on how to avoid dumping at landfill sites as the space has currently become an issue. Researchers globally will learn how to go up through the Technology Readiness Levels (TRL) from basic research through prototype development and finally up to commercialization in projects related to the construction.
Global material crises are imminent. In the very near future, recycling will no longer be a choice made by those concerned about the environment, but a necessity for all. This means a paradigm shift in domestic behavior, manufacturing, construction, and design is inevitable. The Architecture of Waste provides a hopeful outlook through examining current recycling practices, rethinking initial manufacturing techniques, and proposing design solutions for second lives of material-objects. The book touches on a variety of inescapable issues beyond our global waste crisis including cultural psyches, politics, economics, manufacturing, marketing, and material science. A series of crucial perspectives from experts cover these topics and frames the research by providing a past, present, and future look at how we got here and where we go next: the historical, the material, and the design. Twelve design proposals look beyond the simple application of recycled and waste materials in architecture—an admirable endeavor but one that does not engage the urgent reality of a circular economy—by aiming to transform familiar, yet flawed, material-objects into closed-loop resources. Complete with over 150 color images and written for both professionals and students, The Architecture of Waste is a necessary reference for rethinking the traditional role of the architect and challenging the discipline to address urgent material issues within the larger design process.
This book provides scholars working in the many disciplines that relate to the concept of the Circular Economy with a cross-disciplinary forum, looking at areas such as: Theory, Policy and Contexts; Improving Resource Efficiency and Reducing Waste; Changing Consumption and Behaviour by Design; and Transforming Technologies of Production.
Waste to Wealth proves that 'green' and 'growth' need not be binary alternatives. The book examines five new business models that provide circular growth from deploying sustainable resources to the sharing economy before setting out what business leaders need to do to implement the models successfully.
The alarming level of greenhouse gases in the environment, fast depleting natural resources and the increasing level of industrial effluents, have made every single manufacturing activity come under the scrutiny of sustainability. When all kinds of waste such as clothes, furniture, carpets, televisions, shoes, paper, food wastes etc. end up in the landfill, only a few of them are naturally decomposed and thus a large majority remains as non-biodegradable. It is for this reason, efforts are concentrated to reduce the burden on earth by this waste, and as far as used textile products are concerned, there are now attempts to recycle or up-cycle. This book addresses the role of sustainability by using textile waste in fashion and textiles with respect to manufacturing, materials, as well as the economic and business challenges and opportunities it poses. This wide-ranging book comprises 19 chapters on the various topics including: Solutions for sustainable fashion and textile industry Agro and bio waste in the fashion industry Innovating fashion brands by using textile waste Waste in handloom textiles Business paradigm shifting: 21st century fashion from recycling and upcycling Utilization of natural waste for sustainable textile coloration Circular economy in fashion and textile from waste Future pathways of waste utilization for fashion Sustainable encapsulation of natural dyes from Plant waste for textiles Agro-waste applications for bio-remediation of textile effluent
The authors and editors of this volume state that with the intensive growth of global industrialization and urbanization, the consumption of various resources and materials, such as energy, minerals, and even water, is increasing at an amazing speed, which poses great pressure on material resources. In addition, the massive utilization of materials has led to low efficiency, resulting in great wastes of resources as well as serious environmental pollutions and degradation, which has severely hindered the sustainable development of economy and society. In order to transit to sustainable development, it is necessary to improved resource efficiency, and circular economy and waste valorization are the best alternative ways for achieving this goal. This book aims to provide an in-depth description of circular economy and waste valorization, make assessments for circular economy and waste valorization in different regions and countries and determine the technological pathways and roadmap for achieving circular economy and waste valorization. More specifically: (1) Conceptions and Theories: Concepts and definitions of circular economy and waste valorization and their nexus and contributions to sustainable development. (2) Policy and Practice: Measurement and assessment of performance or sustainability for implementing circular economy and waste valorization. (3) Pathways and Prospects: Identification and prioritization of the barriers, strategies, technologies, and pathways for achieving circular economy and waste valorization. The book systematically and comprehensively introduces the definitions, concepts, framework and nexus of circular economy and waste valorization, analyzes and measures their performance and sustainability and provides the methods for investigating and prioritizing the barriers and strategies and determining the pathways and roadmap for their development.
