Sustainable Soils Re Engineering

Geotechnical engineering, civil engineering, and other allied engineering disciplines have, for a long time, shifted from problem solving to creating problems that plague our planet. This book, Sustainable Soils Re-Engineering, is here to point the world to a more environmentally friendly approach to solving problems using engineering skills. This book moved from the use of cement, which contribute hugely to global warming through the release of oxides of carbon, to the utilization of derivatives of solid-waste materials in the form of ash or powder. These are derived through direct combustion and crushing. Yet one may wonder where the oxides of carbon released during combustion is managed. This book also proposes a model through which oxides of carbon are entrapped through a controlled combustion mechanism. That way, ash is generated for use as geomaterial, and the environment is left healthy. The operation of utilizing solid waste equally rids the environment of its plaguing condition in the process. Also the more practical approach exposed in this book will assist researchers across the world to explore new and novel grounds toward helping humanity. More on this is the bringing forth of mathematical methods like the extreme vertex design adopted in modeling properties of re-engineered soils.

The articles presented in this book deal with the attempts made by the scientists and practitioners to address contemporary issues in geoenvironmental engineering such as characterization of dredged sediments, geomaterials & waste, valorization of waste, sustainability in waste management, and some other geoenvironmental issues that are becoming quite relevant in today's world. With high urbanization rates, advancement in technologies, and changes in consumption behavior of people, wastes generated through the daily activities of individuals and organizations pose many challenges in their management.

Over the last 50 years there has been rapid development of construction techniques, analytical methods and materials for use in ground engineering. One of the major techniques which has been developed is soil strengthening or reinforcement whereby man-made elements are included within geological material to provide a stabilised mass. Various products have been developed for retaining systems, slope stabilisation, etc.More recently, environmental concerns and the focus on sustainable development have led to the examination of materials based on renewable resources for use in ground engineering.In this book, the applications of both vegetable and man-made fibres in situations where there is a requirement for short-term ground reinforcement are examined and discussed. The use of vegetable fibre geotextiles (VFG), particularly in erosion control and soil reinforcement, is covered in detail, with examples from various civil engineering applications.Over the last 50 years there has been rapid development of construction techniques, analytical methods and materials for use in ground engineering.

This edited volume presents the proceedings of the 20th CIRP LCE Conference, which cover various areas in life cycle engineering such as life cycle design, end-of-life management, manufacturing processes, manufacturing systems, methods and tools for sustainability, social sustainability, supply chain management, remanufacturing, etc.

This book explores how integrated management of environmental resources via a Nexus Approach can help to achieve Sustainable Development Goals (SDGs). It takes a process-oriented view on what should or needs to be done to implement a Nexus Approach and how this relates to SDGs. After sketching the background and conceptual outline, contributions to the book explore key aspects of monitoring and implementation. Specifically, they: focus on the importance of monitoring resource use and how to advance it at the international level to support SDG implementation, exemplify the resources perspective on the nexus approach by exploring how to close the nitrogen cycle and stay within planetary boundaries, elaborate on proven and emerging strategies for nexus implementation, highlighting means to enhance, monitor and analyse stakeholder participation, explain how the horizontal and vertical nexus dimensions interact and can support SDG implementation. The book sheds new light on key aspects of the interrelation between SDGs and the Nexus Approach and provides specific recommendations how to advance it.

This volume comprises select papers presented during the Indian Geotechnical Conference 2018. This volume focuses on discussing the many challenges encountered in geoenvironmental engineering. The book covers sustainability aspects related to geotechnical engineering, problematic soils and ground improvement, use of geosynthetics and concepts of soil dynamics. The contents of this book will be useful to researchers and professionals working in geo-environmental engineering and to policy makers interested in understanding geotechnical concerns related to sustainable development. .

Global food security is dependent on ecologically viable production systems, but current agricultural practices are often at odds with environmental sustainability. Resolving this disparity is a huge task, but there is much that can be learned from traditional food production systems that persisted for thousands of years. Ecoagriculture for a Sustainable Food Future describes the ecological history of food production systems in Australia, showing how Aboriginal food systems collapsed when European farming methods were imposed on bushlands. The industrialised agricultural systems that are now prevalent across the world require constant input of finite resources, and continue to cause destructive environmental change. This book explores the damage that has arisen from farming systems unsuited to their environment, and presents compelling evidence that producing food is an ecological process that needs to be rethought in order to ensure resilient food production into the future. Cultural sensitivity Readers are warned that there may be words, descriptions and terms used in this book that are culturally sensitive, and which might not normally be used in certain public or community contexts.

Geofluids: Developments in Microthermometry, Spectroscopy, Thermodynamics, and Stable Isotopes is the definitive source on paleofluids and the migration of hydrocarbons in sedimentary basins—ideal for researchers in oil and gas exploration. There’s been a rapid development of new non-destructive analytical methods and interdisciplinary research that makes it difficult to find a single source of content on the subject of geofluids. Geoscience researchers commonly use multiple tools to interpret geologic problems, particularly if the problems involve fluid-rock interaction. This book perfectly combines the techniques of fluid inclusion microthermometry, stable isotope analyses, and various types of spectroscopy, including Raman analysis, to contribute to a thorough approach to research. Through a practical and intuitive step-by-step approach, the authors explain sample preparation, measurements, and the interpretation and analysis of data related to thermodynamics and mineral-fluid equilibria. Features working examples in each chapter with step-by-step explanations and calculations Broad range of case studies aid the analytical and experimental data Includes appendices with equations of state, stable isotope fractionation equations, and Raman identification tables that aid in identification of fluid inclusion minerals Authored by a team of expert scientists who have more than 60 years of related experience in the field and classroom combined
