Book Description
Phosphorus removed from the land must be recovered and reused/ recycled effectively. In parallel, value streams that come from the process of mining PR and making phosphoric acid can also be exploited, most notably the recovery of uranium from the phosphoric acid for use as a fuel for nuclear energy and the use of the co-product phosphogypsum in agriculture. Accordingly, this paper seeks first a sustainable management approach, derived from linking innovative micro-level 'closed system' concepts about the behaviour of soil and fertiliser P with the macro-level perspective of the efficient use, and reuse, of the global phosphate resource for food and energy security; secondly, it examines risks and benefits in the proposed managed P life-cycle with a view to setting out an achievable, socially acceptable and environmentally sustainable management regime for a resource that might otherwise deplete unnecessarily quickly or even run out. Calculating phosphate reserves and relative depletion rates may be, by contrast, a very elusive issue given a) the extreme commercial sensitivity of the data, and b) the dependency of many developing economies on access to phosphate fertiliser for their agriculture, on the industry's contribution to their national GDP, and on hard currency earnings from sales of rock and phosphate products in the global market.

Book Description
Provides complete coverage of the recovery of mineral nutrients from biomass and organic waste This book presents a comprehensive overview of the potential for mineral recovery from wastes, addressing technological issues as well as economic, ecological, and agronomic full-scale field assessments. It serves as a complete reference work for experts in the field and provides teaching material for future experts specializing in environmental technology sectors. Biorefinery of Inorganics: Recovering Mineral Nutrients from Biomass and Organic Waste starts by explaining the concept of using anaerobic digestion as a biorefinery for production of an energy carrier in addition to mineral secondary resources. It then discusses the current state of mineral fertilizer use throughout the world, offering readers a complete look at the resource availability and energy intensity. Technical aspects of mineral recovery organic (waste-)streams is discussed next, followed by an examination of the economics of biobased products and their mineral counterparts. The book also covers the environmental impact assessment of the production and use of bio-based fertilizers; modelling and optimization of nutrient recovery from wastes; and more. Discusses global production and consumption of mineral fertilizers Introduces technologies for the recovery of mineral NPK from organic wastes and residues Covers chemical characterization and speciation of refined secondary resources, and shows readers how to assess biobased mineral resources Discusses applications of recovered minerals in the inorganic chemistry sector Compares the economics of biobased products with current fossil-based counterparts Offers an ecological assessment of introducing biobased products in the current fertilizer industry Edited by leading experts in the field Biorefinery of Inorganics: Recovering Mineral Nutrients from Biomass and Organic Waste is an ideal book for scientists, environmental engineers, and end-users in the agro-industry, the waste industry, water and wastewater treatment, and agriculture. It will also be of great benefit to policy makers and regulators working in these fields.

Book Description
This book describes a pathway for sustainable phosphorus management via the Global Transdisciplinary Processes for Sustainable Phosphorus Management project (Global TraPs). Global TraPs is a multi-stakeholder forum in which scientists from a variety of disciplines join with key actors in practice to jointly identify critical questions and to articulate what new knowledge, technologies and policy processes are needed to ensure that future phosphorus use is sustainable, improves food security and environmental quality and provides benefits for the poor. The book offers insight into economic scarcity and identifies options to improve efficiency and reduce environmental impacts of anthropogenic phosphorus flows at all stages of the supply and use chain.

Book Description
In the 21st century, management of municipal solid waste (MSW) continues to be an important environmental challenge facing the U.S. Climate change is also a serious issue, & the U.S. is embarking on a number of voluntary actions to reduce the emissions of greenhouse gases (GHGs) that can intensify climate change. By presenting material-specific GHG emission factors for various waste management options, this report examines how the two issues -- MSW management & climate change -- are related. The report's findings may be used to support a variety of programs & activities, including voluntary reporting of emission reductions from waste management practices. Charts, tables & graphs.

Book Description
When humanity first glimpsed planet Earth from space, the unity of the system that supports humankind entered the popular consciousness. The concept of the Earth's atmosphere, biosphere, oceans, soil, and rocks operating as a closely interacting system has rapidly gained ground in science. This new field, involving geographers, geologists, biologists, oceanographers, and atmospheric physicists, is known as Earth System Science. In this Very Short Introduction, Tim Lenton considers how a world in which humans could evolve was created; how, as a species, we are now reshaping that world; and what a sustainable future for humanity within the Earth System might look like. Drawing on elements of geology, biology, chemistry, physics, and mathematics, Lenton asks whether Earth System Science can help guide us onto a sustainable course before we alter the Earth system to the point where we destroy ourselves and our current civilisation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description
Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.
