Progress Of Recycling In The Built Environment

This report is a useful tool for countries starting to recycle aggregates or construction and demolition waste. It contains the latest developments in this field, introduces a completely new approach to the procedure of proportioning concrete mixtures with recycled aggregate, references recent publications, opinions and discrepancies in relation to the durability of recycled concrete, such as freeze-thaw standards, studies of chloride penetration and diffusion, and sulfate attacks, the use of the fine fraction This volume will be of interest to recyclers, researchers and consumers.

Designing for Zero Waste is a timely, topical and necessary publication. Materials and resources are being depleted at an accelerating speed and rising consumption trends across the globe have placed material efficiency, waste reduction and recycling at the centre of many government policy agendas, giving them an unprecedented urgency. While there has been a considerable literature addressing consumption and waste reduction from different disciplinary perspectives, the complex nature of the problem requires an increasing degree of interdisciplinarity. Resource recovery and the optimisation of material flow can only be achieved alongside and through behaviour change to reduce the creation of material waste and wasteful consumption. This book aims to develop a more robust understanding of the links between lifestyle, consumption, technologies and urban development.

”Reduce, Reuse, Recycle, and Recover“ is the sustainable guideline that has replaced the ”Take, Make, Waste“ attitude of the industrial age. Based on their background at the ETH Zurich and the Future Cities Laboratory in Singapore, the authors provide both a conceptual and practical look into materials and products which use waste as a renewable resource. This book introduces an inventory of current projects and building elements, ranging from marketed products, among them façade panels made of straw and self-healing concrete, to advanced research and development like newspaper, wood or jeans denim used as isolating fibres. Going beyond the mere recycling aspect of reused materials, it looks into innovative concepts of how materials usually regarded as waste can be processed into new construction elements. The products are organized along the manufacturing processes: densified, reconfigured, transformed, designed and cultivated materials. A product directory presents all materials and projects in this book according to their functional uses in construction: load-bearing, self-supporting, insulating, waterproofing and finishing products.

Construction and Demolition Waste (CDW), from the construction, maintenance, renovation and demolition of buildings and structures, represents a large proportion of the waste in industrialized societies. Compared to other forms, such as household waste, more than 90% of CDW can be used as a resource and a substitute for construction materials, especially for primary, natural raw materials. Reuse, recovery and recycling depends on the quality and market for the materials, and the environmental impact of the processes for conversion of CDW from old structures to its use in new structures. However, the utilization today of CDW products as secondary resources is marginal. Most CDW is deposited or used as fill material, and the opportunities of high quality recycling are generally neglected. This book presents the opportunities for the sustainable and resource efficient utilisation of CDW, focusing on recycling of concrete and masonry as the major forms of CDW. The recycling of gypsum, timber, mineral wool, asphalt and other types are also described. Its aim is to present a chain of value and material streams in the transformation of obsolete buildings and structures into new buildings and structures. It takes a holistic view, focusing on the lifecycle economy (the circular economy) and integrated management aspects of various scenarios ranging from high industrial urban renewal to debris removal and management after disasters and conflicts. It is based on the author ́s 35 years of research and development combined with practical international experience within the demolition and recycling area. It addresses students, architects, civil engineers, building owners, public authorities and others working in urban planning, demolition and resource management in the building and construction sector and in the reconstruction of damaged buildings after disasters and wars.

This open access book explores the strategic importance and advantages of adopting multidisciplinary and multiscalar approaches of inquiry and intervention with respect to the built environment, based on principles of sustainability and circular economy strategies. A series of key challenges are considered in depth from a multidisciplinary perspective, spanning engineering, architecture, and regional and urban economics. These challenges include strategies to relaunch socioeconomic development through regenerative processes, the regeneration of urban spaces from the perspective of resilience, the development and deployment of innovative products and processes in the construction sector in order to comply more fully with the principles of sustainability and circularity, and the development of multiscale approaches to enhance the performance of both the existing building stock and new buildings. The book offers a rich selection of conceptual, empirical, methodological, technical, and case study/project-based research. It will be of value for all who have an interest in regeneration of the built environment from a circular economy perspective.

The construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources. Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new “green” design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined. Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.

How is it possible to keep the immense deposits of raw materials in buildings "active" and realise environmentally sustainable buildings in the long term? Besides "sufficiency, consistency and efficiency", this goal implies the intelligent use of resources, the recyclability of structures, circular construction methods that reuse decommissioned materials, in short "urban mining". This requires a rethink in planning and execution, thus posing a great challenge for architects and engineers. The Recycling Manual provides the necessary expertise for the associated paradigm shift in construction. In addition to successful project examples, this comprehensive and detailed guide provides in-depth explanations on calculation methods and tendering aspects.
