This book is dedicated to the reuse of waste and residues from the agricultural sector. Plant residues, as well as animal manure and residues from animal breeding, contain useful elements that can be processed for production of fertilizers, compost for soil recultivation, and biofuels. The emerging energy and resources crisis calls for development of sustainable reuse of waste and residues. This book contains eight chapters divided into four sections. The first section contains the introductory chapter from the editor. The second section is related to the preparation of fertilizers and compost for soil amelioration from agricultural residues and waste water. The third section considers the use of agricultural waste for solid biofuels and biogas. The fourth section discusses sustainability and risk assessment related to the use of agricultural waste and residues.

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. Wie gelingt es, die immensen Rohstoffvorkommen im Gebäudebestand »aktiv« zu halten und dauerhaft umweltverträgliche Gebäude zu realisieren? Neben »Suffizienz, Konsistenz und Effizienz« impliziert dieses Ziel den intelligenten Einsatz von Ressourcen, die Recyclingfähigkeit von Konstruktionen, ein kreislauffähiges Bauen, kurz: »Urban Mining« im Bauwesen. Dies erfordert ein grundsätzliches Umdenken in Planung und Ausführung - und damit eine große Herausforderung für Architekten und Ingenieure. Der Recycling Atlas liefert das nötige Fachwissen für den damit verbundenen Paradigmenwechsel im Bauen. Neben gelungenen Projektbeispielen zeigt ein umfangreicher Leitdetailkatalog relevante Bauteilanschlüsse und liefert ausführliche Erläuterungen zu Berechnungsmethoden und Ausschreibungsaspekten.

An examination of the global trade and traffic in discarded electronics that reframes the question of the "right" thing to do with e-waste. The prevailing storyline about the problem of electronic waste frames e-waste as generated by consumers in developed countries and dumped on people and places in developing countries. In Reassembling Rubbish , Josh Lepawsky offers a different view. In an innovative analysis of the global trade and traffic in discarded electronics, Lepawsky reframes the question of the "right" thing to do with e-waste, mapping the complex flows of electronic materials. He counters the assumption that e-waste is a post-consumer problem, pointing out that waste occurs at all stages of electronic materials' existence, and calls attention to the under-researched world of reuse and repair. Lepawsky explains that there are conflicting legal distinctions between electronic waste and non-waste, and examines a legal case that illustrates the consequences. He shows that patterns of trade do not support the dominant narrative of e-waste dumping but rather represent the dynamic ecologies of repair, refurbishment, and materials recovery. He asks how we know waste, how we measure it, and how we construe it, and how this affects our efforts to mitigate it. We might not put so much faith in household recycling if we counted the more massive amounts of pre-consumer electronic waste as official e-waste. Lepawsky charts the "minescapes," "productionscapes", and "clickscapes" of electronics, and the uneven "discardscapes" they produce. Finally, he considers both conventional and unconventional e-waste solutions, including decriminalizing export for reuse, repair, and upgrade; enabling ethical trade in electronics reuse, repair, refurbishment, and recycling; implementing extended producer responsibility; and instituting robust forms of public oversight.

Having a solid understanding of materials recycling is of high importance, especially due the growing use of composites in many industries and increasingly strict legislation and concerns about disposal of composites by landfill or incineration. Recycling of Plastics, Metals, and Their Composites provides a comprehensive review of the recycling of waste polymer and metal composites. It provides readers with the latest advances and covers fundamentals of recycled polymer and metal composites such as preparation, morphology, and physical, mechanical, thermal, and flame-retardancy properties. Offers a state-of-the-art review of recycling of polymer composites and metal composites for sustainability Describes a life cycle analysis to help readers understand the true potential value and market of these recycled materials Details potential applications of recycled polymer and metal composites Includes performance of natural fiber-reinforced recycled thermoplastic polymer composites under aging conditions and recycling of multi-material plastics Covers recycling technologies, opportunities, and challenges for polymer-matrix composites This work targets technical professionals working in the metal and polymer industries, as well as researchers, scientists, and advanced students. It is also of interest to decision makers at material suppliers, recycled metal and polymer product manufacturers, and governmental agencies working with recycled metal and polymer composites.
