Copper is one of the three most important metals in the world economy, and the only one of the three that is comparatively scarce in the earth's crust. Known reserves will only last a few decades at projected rates of consumption. While some substitution possibilities exist for some of its applications, copper is uniquely valuable as a conductor of electricity in a world that is rapidly electrifying. This fact makes the copper life cycle an appropriate subject for holistic analysis. This book, which includes a quantitative demand forecasting model, is based on a study commissioned by the International Institute for Environment and Development (IIED) for the World Business Council for Sustainable Development (WBCSD) fills that need for the first time. Among the conclusions of the study are the following. The medium-term prospects for copper producers and copper consuming industries include (1) more intensive exploration into more remote regions, (2) utilization of lower grade ores resulting in more mine wastes and associated waste disposal problems, (3) more intensive mining efficient ore reduction processes, (4) dramatic price increases when the current glut works itself out, (5) significant changes in the patterns of consumption (increasingly electrical applications), (6) sharp increases in the need for recovering and recycling old scrap copper in the future, (7) a significant buildup of copper and by-products (especially arsenic) either in use or in the human environment. Similar implications can be drawn for two other scarce and toxic metals - lead and zinc - often found in geological association with copper.

Flexible Incentives for the Adoption of Environmental Technologies in Agriculture identifies and structures more flexible economic incentives for the achievement of environmental goals in agriculture. It provides a conceptual framework and presents case studies that analyze how flexible incentives can address environmental problems that are caused by agricultural production. The book brings together economists, agency personnel and political economists for the purpose of exploring how new cutting-edge economic tools could be developed and applied to environmental problems. The goal of the book is to complement and to expand the economic theory of environmental regulation and technology adoption with new research findings. The key theme of this book is the important role technology takes when addressing environmental problems. New technologies and technical development are broadly defined to include economic instruments, innovative ways to communicate environmental information, new economic institutions, and education. This book is designed for public and private policymakers, government analysts, teachers, researchers and students who specialize in the fields of natural resources, agricultural economics and environmental regulation. It provides a fresh perspective on what types of incentives may be used to lead us to the desired environmental outcomes and offers new ideas about the types of economic instruments that may achieve these outcomes.
The last two decades have seen a phenomenal growth of the field of genetic or biochemical engineering and have witnessed the development and ultimately marketing of a variety of products-typically through the manipulation and growth of different types of microorganisms, followed by the recovery and purification of the associated products. The engineers and biotechnologists who are involved in the full-scale process design of such facilities must be familiar with the variety of unit operations and equipment and the applicable regulatory requirements. This book describes current commercial practice and will be useful to those engineers working in this field in the design, construction and operation of pharmaceutical and biotechnology plants. It will be of help to the chemical or pharmaceutical engineer who is developing a plant design and who faces issues such as: Should the process be batch or continuous or a combination of batch and continuous? How should the optimum process design be developed? Should one employ a new revolutionary separation which could be potentially difficult to validate or use accepted technology which involves less risk? Should the process be run with ingredients formulated from water for injection, deionized water, or even filtered tap water? Should any of the separations be run in cold rooms or in glycol jacketed lines to minimize microbial growth where sterilization is not possible? Should the process equipment and lines be designed to be sterilized in-place, cleaned-in-place, or should every piece be broken down, cleaned and autoclaved after every turn?"

In addition an assessment of ethical aspects of livestock biotechnology and considerations regarding animal welfare implications are covered. The study is addressed to science, industry and politics.
Fungi playa major role in the sustainability of the biosphere, and mycorrhizal fungi are essential for the growth of many of our woods and forests. The applications of fungi in agriculture, industry and biotechnology remain of paramount importance, as does their use as a source of drugs and to help clean up our environment. This volume contains key papers from the conference 'From Ethnomycology to Fungal Biotechnology: Exploiting Fungi from Natural Resources for Novel Products'. This was the first international scientific conference covering the transfer of traditional remedies and processes in ethnomycology to modern fungal biotechnology. The conference was held at Simla, Himachal Pradesh, India from 15 to 16 December 1997. The key subject areas addressed in the conference were the issues of exploring and exploiting fungal diversity for novel leads to new antibiotics, enzymes, medicines and a range of other leads for wood preservation, biological control, agricultural biotechnology and the uses of fungi in the food industry. The conference programme included key-note presentations followed by poster sessions and general discussion. The book is broadly based, covering five main areas: Ethnomycology, Fungal Biotechnology, Biological Control, Mycorrhizal Fungi and Fungal Pests. There is no doubt that in the past fungi have played a key role in ethnomycological remedies and that in the future they will continue to attract the interest of a wide range of disciplines ranging from environmental conservation, agriculture and the food industry to wood preservation and aerobiological studies.
The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions."

Readers will find here a summary of the syngas utilization and the bio-oil characterization and potential use as an alternative renewable fuel and source for chemical feedstocks. Particular attention is also given to the anaerobic digestion-based and Organosolv biorefineries. The last part of the book examines relevant products and components such as alcohols, hydrocarbons, bioplastics and lignin, and offers a sustainability evaluation of biorefineries.
The scope of the field of biotechnological processes is very wide, covering such processes as fermentations for production of high-valued specialist chemicals (e.g. pharmaceuticals), high-volume production of foods and feeds (e.g. yoghurt, cheese, beer), as well as biological waste treatment, handling solid (composting), liquid (activated sludge) and gaseous wastes (biofilters). Compared to other engineering disciplines, the introduction of modern optimization and control strategies is lagging behind. Two main reasons can be identified. First, the living organisms (or part thereof) that are central to these processes make the mathematical modeling of the processes a difficult task, and, since models are central to the development of control systems, the on-line control problem is also complex. The other difficulty stems from the absence, in most cases, of cheap and reliable instrumentation suited to real-time monitoring. In this book a number of advanced techniques is introduced to deal with these problems. In the first part modern on-line hardware sensors are discussed in detail (FIA, viable biomass measurement, membrane inlet mass spectrometry, flow cytometry, microcalorimetry). In the second part, novel model-based process diagnosis and control techniques are dealt with, including advances in bioprocess modeling and identification, data processing, software sensor design, and on-line control algorithms. The book is directed at engineers, researchers, and students in the field of process control and systems theory as applied to industrial biotechnological processes, as well as at bioengineers who have some background in control engineering and wish to increase their understanding ofhow advanced control theory applies to biological processes.

Since its first systematic application during the 1970s, bioremediation, or the exploitation of a biological system's degradative potential to combat toxic pollutants such as heavy metals, polyaromatic hydrocarbons (PAH), cyanides, and radioactive material, has proven itself over time, and the many advances in molecular techniques have only amplified its utility. In Bioremediation: Methods and Protocols, experts in the field explore imaginative and ambitious multidisciplinary techniques that will enable more predictable removal of pollutants from a variety of environments. The easy-to-follow volume addresses some of the broader issues such as the effect of the environment in determining the availability and fate of organic and inorganic compounds and how choices around the most appropriate bioremediation process can be arrived at, as well as detailed complementary techniques that support the effective deployment and monitoring of a bioremediation approach. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Bioremediation: Methods and Protocols offers researchers a series of invaluable techniques certain to enhance their work with environmental contamination."
Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, "system biology" and "omics approaches" in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.
Additive manufacturing (AM) and subtractive manufacturing (SM) offer numerous advantages in the production of single and multiple components. They provide incomparable design independence and are used to fabricate products in several industries, e.g.: aeronautic, automotive, biomedical, etc. The book presents recent results of processes including 3D printing, SLS (selective laser sintering), EBM (electron beam melting) and Precise Cutting and Drilling.
Increasing population and industrialization are the key pollutant contributors in water bodies. The wastes generated by industries are highly hazardous for humans and the ecosystem and require a comprehensive and effective treatment before being discharged into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of toxic pollutants. Phycoremediation has been gaining attention due to its mutual benefit in wastewater treatment and for valuable algae biomass production. Wastewater, especially sewage and industrial effluents, is rich in pathogenic organisms, organic and inorganic compounds and heavy metals that adversely affect human and aquatic life. Microalgae use these inorganic compounds and heavy metals for their growth. In addition, they also reduce pathogenic organisms and release oxygen to be used by bacteria for decomposition of organic compounds in a secondary treatment. In this book, the potential of microalgae in wastewater treatment, their benefits, strategies, and challenges are discussed. The increasing need of finding innovative, low-cost, low-energy, sustainable and eco-friendly solutions for wastewater treatment makes the publication of a book on phycoremediation timely and appropriate. Features: (1) Deals with the most emerging aspects of algal research with special reference to phycoremediation. (2) Studies in depth diversity, mutations, genomics and metagenomics study (3) An eco-physiology, culturing, microalgae for food and feed, biofuel production, harvesting of microalgae, separation and purification of biochemicals.
In 1992, a group of scientists including molecular biologists, microbiologists, population biolo gists, ecologists, human geneticists, moral philosophers and others met discussing the state of affairs regarding the deliberate or unintentional release of genetically modified organisms. The proceedings of this meeting were subsequently published by Birkhauser Verlag as Transgenic Organisms: Risk Assessment of Deliberate Release (K. Wohrmann and J. Tomiuk). Since then we have gained many new insights that are also worthy of discussion. And although other equally important scientific views on the release of genetically modified organisms exist, we have mainly concentrated on aspects of population biology and evolution. The results of a second meeting in 1995 are summarized here. We are grateful to colleagues and friends for their help in the translation, correction and review of the authors' contributions. We especially want to thank Jutta Bachmann, Donna Devine, Diana von Finck, Friedrich Laplace, Volker Loeschcke, Rolf Lorenz, Dave Parker and Trevor Petney. A grant (BMFT N' 0311035) from the Ministerium fUr Forschung und Technologie der Bundesrepublik Deutschland again made possible the continuation of this cooperative endeavour."
