Minerals, Metals and Sustainability examines the exploitation of minerals and mineral products and the implications for sustainability of the consumption of finite mineral resources and the wastes associated with their production and use. It provides a multi-disciplinary approach that integrates the physical and earth sciences with the social sciences, ecology and economics. Increasingly, graduates in the minerals industry and related sectors will not only require a deep technical and scientific understanding of their fields (such as geology, mining, metallurgy), but will also need a knowledge of how their industry relates to and can contribute to the transition to sustainability. Minerals, Metals and Sustainability is an important reference for students of engineering and applied science and geology; practising engineers, geologists and scientists; students of economics, social sciences and related disciplines; professionals in government service in areas such as resources, environment and sustainability; and non-technical professionals working in the minerals industry or in sectors servicing the minerals industry.

This groundbreaking book covers the recent advances in sustainable technologies and developments, and describes how green chemistry and engineering practices are being applied and integrated in various industrial sectors. Over the past decade, the population explosion, rise in global warming, depletion of fossil fuel resources and environmental pollution have been the major driving force for promoting and implementing the principles of green chemistry and sustainable engineering in all sectors ranging from chemical to environmental sciences. It plays a growing role in the chemical processing industries. Green chemistry and engineering are relatively new areas focused on minimizing generations of pollution by utilizing alternative feedstocks, developing, selecting, and using less environmentally harmful solvents, finding new synthesis pathways, improving selectivity in reactions, generating less waste, avoiding the use of highly toxic compounds, and much more. In an effort to advance the discussion of green chemistry and engineering, this book contains 19 chapters describing greener approaches to the design and development of processes and products. The contributors describe the production of third generation biofuels, sustainable and economic production of hydrogen by water splitting using solar energy, efficient energy harvesting, mechanisms involved in the conversion of biomass, green nanocomposites, bio-based polymers, ionic liquids as green solvents, sustainable nitrogen fixation, bioremediation, and much more. The book aims at motivating chemists and engineers, as well as postgraduate and PhD students and postdocs to pay attention to an acute need for the implementation of green chemistry principles in the field of chemical engineering, biomedical engineering, agriculture, environmental engineering, chemical processing and material sciences.

The merits and demerits of various extraction methods are highlighted, with possible suggestions for improvements. The feasibility of hybrid extraction techniques, as well as the sustainability and environmental impact of every process, is explored. Offers a comprehensive review of different techniques used in recycling technology for urban mining of precious metals Describes the concept of urban mining and its correlation with circular economy Discusses feasibility of precious metal extraction and urban mines scope and their potential Explains the subject in-context of sustainability while describing chemistry fundamentals and industrial practices Provides technical flow sheets for urban mining of precious metals with diversity of lixiviant This book is aimed at graduate students and researchers in extractive metallurgy, hydrometallurgy, chemical engineering, chemistry, and environmental engineering.

This book gathers contributions from scientists and industry representatives on achieving a sustainable bioeconomy. It also covers the social sciences, economics, business, education and the environmental sciences. There is an urgent need to optimise and maximise the use of biological resources, so that primary production and processing systems can generate more food, fibre and other bio-based products with less environmental impacts and lower greenhouse gas emissions. In other words, we need a “sustainable bioeconomy” – a term that encompasses the sustainable production of renewable resources from land, fisheries and aquaculture environments and their conversion into food, feed, fibre bio-based products and bio-energy, as well as related public goods. Despite the relevance of achieving a sustainable bioeconomy, there are very few publications in this field. Addressing that gap, this book illustrates how biological resources and ecosystems could be used in a more sustainable, efficient and integrated manner – in other words, how the principles of sustainable bioeconomy can be implemented in practice. Given its interdisciplinary nature, the field of sustainable bioeconomy offers a unique opportunity to address complex and interconnected challenges, while also promoting economic growth. It helps countries and societies to make a transition and to use resources more efficiently, and shows how to rely less on biological resources to satisfy industry demands and consumer needs. The papers are innovative, cross-cutting and include many practice-based lessons learned, some of which are reproducible elsewhere. In closing, the book, prepared by the Inter-University Sustainable Development Research Programme (IUSDRP) and the World Sustainable Development Research and Transfer Centre (WSD-RTC), reiterates the need to promote a sustainable bioeconomy today.

Green Sustainable Process for Chemical and Environmental Engineering and Science: Microbially-Derived Biosurfactants for Improving Sustainability in Industry explores the role biosurfactants may play in providing more sustainable, environmentally benign, and economically efficient solutions for mitigating challenges experienced in the industrial sector.

Drawing on the knowledge of its expert team of global contributors, the book provides useful insights for all those currently or potentially interested in developing or applying biosurfactants in their own work. As awareness and efforts to develop greener products and processes continue to grow in the chemistry community, biosurfactants are garnering much attention for the potential roles they can play, both in reducing the use and production of more toxic products and as tools for addressing existing problems. - Highlights effective bioprocessing techniques, bioprocessing, agrowaste, and factors affecting production - Reflects on differing strains of fungi, bacteria, actinomycetes and yeast, and reviews genetic modification of such strains for enhanced biosurfactant production - Explores the use of biosurfactants across a broad range of industrial applications

This book broadly explains the requirement to focus on core components in a business and provides a case study of open-pit mining operations throughout the book to understand the management perspective of large organizations. With globalized approaches of large businesses and the rising requirement of understanding the needs of modern organizations, it is necessary to focus on key areas of businesses to ensure sustainability of operations. Organizations look into achieving a high return on investments and short-term measures in increasing sales or revenue is considered unsuitable. It is a necessity to look for sustainability and continuous methods of innovation to boost efficiency. This book provides a case study based on large organizations and uses qualitative methodologies where data was collected using in-depth interviews of respondents from various mining companies in the top and middle-level management from different parts of the world, detailing the state of the art of information systems currently used in large scale open-pit miming (LSOPM). This book provides a sound knowledge of cutting-edge factors to the reader for managing the business to attain operational excellence and long-term sustainability, and caters to a broad spectrum of management and technical readers.
