Available in PDF, EPUB and Kindle. Book excerpt: Economic growth and rising levels of consumption in developing and developed countries has been observed as being deeply coupled with natural resource usage and material consumption. The increasing need for natural resources has raised concerns regarding issues such as resource scarcity, undesirable environmental impacts due to material extraction, primary production, and suboptimal product disposal, and social or political tensions. Product End-of-Life (EoL) options, such as reusing or recycling, attempt to limit or reduce the amount of waste sent to a landfill, providing strategic means to decouple the link between economic growth and resource usage. These EoL options have the potential to close material loops, further utilizing wastes as resources, reducing environmental impacts, conserving natural resources, reducing material prices, and providing job opportunities in developing countries. Remanufacturing, on the other hand, is a unique EoL option due to increasing the number of life cycles of a product before final disposal. First, recurring environmental benefits, such as emission and raw material extraction avoidance are obtained with each additional product life cycle. Second, individual resource efficiency yields increase through product remanufacture. Resource efficiency or, using more with less will continue to compound with each additional life cycle. Third, recirculating products decreases the demand and dependency for primary resource production, further closing the material loop and creating a more circular economy. In addition, remanufacturing can initiate more preferable EoL options such as recovery, recycling, and waste reduction. While remanufacturing offers numerous benefits, there is significant lack of literature and books covering the fundamentals of operations, technologies and business models. The proposed book will provide in-depth coverage of remanufacturing fundamentals and its strong link to circular economy and resource efficiency.

This book was released on 2008 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recycling is one of the popular ways to ensure that the product is environmental friendly. There are several value recovery processes, including cannibalization and remanufacturing. However, the design of most products does not favor the recovery of added value. Product designed for optimal marketing and ease of manufacturing are not necessarily good candidates for a recovery scheme. Design measure such as recyclability, disassemblability, and reusability are defined and used as the basic of the product recovery time. This project proposed a framework for design method that adopts the environmental - friendly philosophy via the concept of reuse, recycle and remanufacture. The bicycle is adopted as a case study. The expected output is the design method that considers 3R philosophy.

Available in PDF, EPUB and Kindle. Book excerpt: The concepts of environmentally friendly manufacturing and ecological reuse of materials have resulted in an increase in the number of disposed products that are disassembled. Moreover, the imposition of EPA regulations is forcing companies to invest in methods for protecting the environrnent. The first strategy in this vein is material recycling. The issue of recycling became important because of the limited landfill space, diminishing natural resources, environmental pollution due to dumping of products containing hazardous materials. Likewise, it is projected that the cost of extracting materials from natural resources is going to be much more expensive when compared to reclaiming materials from disposed products. The above issues bring to light a new concept called demanufacturing. Demanufactuing includes product disassembly, part reuse and remanufacturing and material recycling. Originally the presence of precious metals in the products made companies to opt for recycling, but the present industry feels that it is possible to have demanufactruing for all product types. In order to recycle or reuse the product one has to perform the operation of disassembly to see what components can be reused and which can be sent for either recycling or disposal. In addition, one has to check the components that are going to disposal for their hazardous nature. Hence the concept of disassembly is very important when recycling is the opted choice. Today, industries are trying to implement disassembly lines at their sites similar to that of assembly lines. Before disassembling, one has to consider the cost of disassembly as there is no definite science or technology available when compared to that of assembly. So the issue of cost of disassembly is making the industry develop some tools which help them quantify the operation of disassembly. Keeping the above issues in concern, this research focuses on developing the theory related to disassembly processes similar to that of assembly processes. The different disassembly processes that are dealt with in this research are Adhesive separation, Chemical dissolution, Cutting, Crushing, Shearing, Shredding and Smelting. These processes are similar to the conventional processes used in the manufacturing industry though the difference lies in the manner the product is handled and the tools required for disassembly in demanufacturing industry. All the above processes are based on some metrics, which will help in evaluating or calculating the disassembly effort. The different metrics that are used in effort estimation are time of disassembly, tools required for disassembly, force (machine/human), accessibility, fixture, any instructions necessary before starting disassembly and risk factor involved with getting hurt (hazard) while the disassembly operation is being performed. The other contribution of the research consists of the development of a generic software tool, which would help to deal with strategic points of focus and also the termination of disassembly operation to maximize revenue.

Download or read book Beyond Recycling written by Fernanda Cruz Rios and published by . This book was released on 2018 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, we use resources faster than they can be replaced. Construction consumes more resources than any other industry and has one of the largest waste streams. Resource consumption and waste generation are expected to grow as the global population increases. The circular economy (CE) is based on the concept of a closed-loop cycle (CLC) and proposes a solution that, in theory, can eliminate the environmental impacts caused by construction and demolition (C&D) waste and increase the efficiency of resources' use. In a CLC, building materials are reused, remanufactured, recycled, and reintegrated into other buildings (or into other sectors) without creating any waste. Designing out waste is the core principle of the CE. Design for disassembly or design for deconstruction (DfD) is the practice of planning the future deconstruction of a building and the reuse of its materials. Concepts like DfD, CE, and product-service systems (PSS) can work together to promote CLC in the built environment. PSS are business models based on stewardship instead of ownership. CE combines DfD, PSS, materials' durability, and materials' reuse in multiple life cycles to promote a low-carbon, regenerative economy. CE prioritizes reuse over recycling. Dealing with resource scarcity demands us to think beyond the incremental changes from recycling waste; it demands an urgent, systemic, and radical change in the way we design, build, and procure construction materials. This dissertation aims to answer three research questions: 1) How can researchers estimate the environmental benefits of reusing building components, 2) What variables are susceptible to affect the environmental impact assessment of reuse, and 3) What are the barriers and opportunities for DfD and materials' reuse in the current design practice in the United States. The first part of this study investigated how different life cycle assessment (LCA) methods (i.e., hybrid LCA and process-based LCA), assumptions (e.g., reuse rates, transportation distances, number of reuses), and LCA timelines can affect the results of a closed-loop LCA. The second part of this study is built on interviews with architects in the United States to understand why DfD is not part of the current design practice in the country.
