Book Description
Red mud is a waste material derived as residual from the Bayer process by the caustic digestion of crushed bauxite at elevated temperature. It is chemically characterized by the presence of Si, Al, Fe, Ca, Ti as well as an array of minor constituents such as Na, K, Cr, Ni, Mn, Cu, Zn and Pb. Red Mud: Production, Composition and Impact begins by giving a brief review of laboratories, in situ and remote sensing techniques applied to characterize the RM waste materials focusing on both standard and novel methods.Next, the authors deal with composite materials based on different kind of polymers and red mud, and attempts to summarize the literature about these kind of materials. A great deal of attention is also paid to the possible applications of these new alternatives to classical materials.The main characteristics of several red muds from own studies and the scientific literature are described, and relevant examples of chemical composition variability of red muds emphasize the variability in chemical and mineralogical composition of red muds.This compilation systematically presents the updated scientific literature data regarding the applications of red mud waste in environmental protection. The authors present aspects related to red mud composition and the types of treatments applied to red mud to enhance its adsorption or catalytic performances. The performance of red mud-adsorbents in the removal of inorganic anions, heavy metals and organic compounds from wastewaters, and gaseous effluents is also discussed.The final chapter reviews the existing technological solutions to valorize the red mud in order to develop other engineering activities. The aim is to provide information on the enormous bauxite and alumina industry in Guinea and to appeal for a global approach to tackle the management of red mud; to assist in economic and technical planning of the issue by scientists, industry-leaders, high level policy makers.

Book Description
When Sophica was abruptly separated from her father as a toddler, she found a haven in Grandmother Gitté. But one sunny day in July, when she was six years old, gendarmes marching and shouting in the streets stopped her dreamy childhood and her hopes to go to school and to be a big girl like her sister. She was deported together with her mother and the whole of the Jewish community of Mihaileni, Romania. On foot, through icy fields, they arrived in eastern Ukraine, a strip of land called Transnistria. Death, illness, brutality, shame, became her daily scenes. Sophica suffered hunger and fear but kept her hopes and sanity, albeit losing her sister and her father and witnessing her mother being viciously attacked. She survived typhus and starvation by being strong and quiet. Herman was a jolly little boy who didn’t care much needing to wear the yellow star and being forbidden from school. He continued playing outside with his friends while his father and brother were sent to a labor camp. At the age of 14, when the Second World War ended, he joined a Jewish youth movement and embarked on a ship to the Promised Land. However, their journey was interrupted and they were taken to a British detention camp in Cyprus. Sophica and Herman were given new names, Shulamit and Tzvi. They met and made a home in Israel. Shulamit/Sophica never mentioned her sad childhood, but the essence of the past found its ways out. Sixty-five years after those events, her daughter comes across a family secret and starts asking questions, inducing Shulamit to break her silence and become again the frightened little Sophica. This book tells her moving childhood story.

Book Description
In this original and provocative study, Zsuzsa Gille examines three scandals that have shaken Hungary since it joined the European Union: the 2004 ban on paprika due to contamination, the 2008 boycott of Hungarian foie gras by Austrian animal rights activists, and the "red mud" spill of 2010, Hungary's worst environmental disaster. In each case, Gille analyzes how practices of production and consumption were affected by the proliferation of new standards and regulations that came with entry into the EU. She identifies a new modality of power—the materialization of politics, or achieving political goals with the seemingly apolitical tools of tinkering with technology and infrastructure—and elucidates a new approach to understanding globalization, materiality, and transnational politics.

Book Description
Sustainable Concrete Made with Ashes and Dust from Different Sources: Materials, Properties and Applications focuses on individual materials, addressing material characterization, their role in the strength and durability of construction materials, and structural applications. Each chapter reflects the current state-of-the-art in terms of the effective and efficient use of the material. Types of ashes covered are Coal Fly Ash, Coal Bottom Ash, Bagasse Ash, MSW Ash, Red Mud, Waste Marble Dust, Sewage Sludge Ash, and Cement Kiln Dust. This book is useful for civil engineers in the design and development of sustainable concrete by utilizing such types of ashes and researchers involved in the design and formulation of new cementitious materials. - Focuses on different types of ashes derived from various sources for use in the development of sustainable concrete - Discusses the economic and environmental impacts, normative restrictions, and implementation in codes and standards related to the use of these by-products/wastes in concretes - Includes coverage of the impact of dust from construction and demolition wastes
