    Zirkuläre Bioökonomie: Für eine nachhaltige Wirtschaft

    Zirkuläre Bioökonomie: Für eine nachhaltige Wirtschaft by Manfred Kircher
    Deutsch | PDF EPUB (True) | 2023 | 49 Pages | ISBN : 365841555X | 5 MB

    Für Lebensmittel, Kleidung, Medizin, Papier, Chemieprodukte sind und bleiben wir auf kohlenstoffhaltige Rohstoffe angewiesen. Um fossile Rohstoffe abzulösen, muss die Industrie auf nachhaltige Kohlenstoffquellen umsteigen. Infrage kommt Biomasse aus der Land- und Forstwirtschaft, die aber selbst begrenzt ist. Das Konzept der zirkulären Bioökonomie sieht deshalb die verstärkte Nutzung von Reststoffen, Bio-Abfällen und CO2 vor. Um die Umstellung der Wirtschaft bis zum Jahr 2045 zu erreichen, müssen Infrastruktur und Rahmenbedingungen zügig angepasst werden.

    Mining and Metallurgical Wastes Based Alkali-Activated Materials by Zengqing Sun
    English | PDF EPUB (True) | 2024 | 306 Pages | ISBN : 9819762847 | 60.8 MB

    This book reviews the recent scientific developments on mining and metallurgical wastes-based alkali-activated materials (MMWAAMs). Enormous quantities of solid wastes are generated during the exploitation of ore deposits and the subsequent processing for materials, causing serious environmental problems. Alkali activation is one of the robust technologies that converts mining and metallurgical wastes into value-added materials and offers technological solutions for efficient stabilization of toxic components in mining and metallurgical wastes. Herein, this book presents the development of the design, processing routes, and performances of mining and metallurgical waste-based alkali-activated materials. It highlights in detail the relationships between the physicochemical characteristics of the source materials and the properties of synthesized binders. From the durability perspective, both the applicability of testing protocols and degradation mechanisms are also reviewed with significant experimental and modeling work presented. Furthermore, the transformation paths of initially toxic components during alkali activation, partitioning characteristics, as well as the assemblages of solubility-controlling mineral phases are discussed for detailed environmental compatibility evaluation. In addition, applications and perspectives for future directions of mining and metallurgical wastes-based alkali-activated materials are illustrated. By bringing state-of-the-art knowledge, this book appeals to a broad readership, particularly researchers engaged in material and environmental science, mining and metallurgical engineering, and other related fields.

    Biological Weathering and the Environment of the Earth

    Biological Weathering and the Environment of the Earth by Tasuku Akagi
    English | PDF EPUB (True) | 2024 | 178 Pages | ISBN : 9819744253 | 25.9 MB

    This book introduces the concept of 'biological weathering.' Weathering, especially chemical weathering, has been recognized as one of the most important processes on Earth because it influences the circulation of elements, including carbon. Weathering has almost always been considered an abiotic process. The book describes the author’s experiments, proving that plant involvement in weathering is a strategy for plants to ingest nutrients from rocks. It is also shown through cultivation experiments and observation of natural diatoms that diatoms and silica obligate plankton dissolve silicate minerals and incorporate silicon and other elements into their frustules. The weathering reaction has also been successfully applied to the previously unexplained relationship between carbon and silica in the ocean’s interior.

    English | PDF EPUB (True) | 2024 | 365 Pages | ISBN : 3031540042 | 21.8 MB

    This book sheds light on this global environmental issue and proposes solutions to reduce contamination through multi-disciplinary approaches. Water is considered a vital resource because it is necessary for all aspects of human and ecosystem survival. However, due to natural processes and anthropogenic activities, various pollutants have been added to the groundwater system. Among these, heavy metals are some of the most serious pollutants. Cd, a toxic heavy metal used in Ni-Cd batteries, the coloration of plastic and various discarded electronic products released into the water system causes serious health issues. The chronic exposure to Cd produces a wide variety of acute and chronic effects in humans.
