Bioenergy Production by Anaerobic Digestion
Interest in anaerobic digestion (AD), the process of energy production through the production of biogas, has increased rapidly in recent years. Agricultural and other organic waste are important substrates that can be treated by AD. This book is one of the first to provide a broad introduction to anaerobic digestion and its potential to turn agricultural crops or crop residues, animal and other organic waste, into biomethane. The substrates used can include any non-woody materials, including grass and maize silage, seaweeds, municipal and industrial wastes. These are all systematically reviewed in terms of their suitability from a biological, technical and economic perspective. In the past the technical competence and high capital investment required for industrial-scale anaerobic digesters has limited their uptake, but the authors show that recent advances have made smaller-scale systems more viable through a greater understanding of optimising bacterial metabolism and productivity. Broader issues such as life cycle assessment and energy policies to promote AD are also discussed.
Access and Benefit-sharing in Global Aquaculture
This is an open access title available under the terms of a CC BY-NC-ND 4.0 License. It is free to read, download and share on Elgaronline.com. This illuminating book incisively surveys the complex legal regime of access and benefit-sharing in key aquaculture countries. With an international focus spanning countries across Africa, Asia, Europe and South America, the authors explore the application of international legal standards and how these translate into domestic measures.
Cladocera
There is a strong tendency now for specialists in various groups of organisms, or in various processes and their consequences, to get together at more or less regular intervals to discuss their subjects. This has hap pened e. g. with the Chironomidae, Ephemeroptera, and Plecoptera among the aquatic insects, and the Rotifera, Copepoda, and Ostracoda among the zooplankton. Finally the scientists working with the Cladocera, who have been isolated from one another for a long time except on a personal basis, have decided to do the same, largely through the initiative and drive of L. Forro. Thus, the First International Symposium on Cladocera was held in Budapest on 12-16 August 1985. Most of the ...
Genetics and Evolution of Aquatic Organisms
This volume brings together, for the first time, a wide range of up-to-the-minute and traditional techniques and approaches to the study of genetics of organisms living in freshwater or marine habitats. Carefully edited chapters are headed by broad review articles against which are set a number of more specific experience papers which demonstrate the breadth and range of approaches currently being undertaken.
Tilapia lake virus disease strategy manual
The purpose of this manual is to inform national policymakers and other stakeholders of issues related to the development of contingency plans for responding to outbreaks of tilapia lake virus disease (TiLVD), which has caused substantial mortalities, up to 90 percent, in populations of both wild and farmed tilapia in Asia, the Americas, and Africa. The causative agent for this disease is tilapia lake virus (TiLV), which infects the liver, spleen, kidney, heart, gill tissues, brain, connective tissues of muscle, and reproductive organs of tilapia. Outbreaks of TiLVD not only have devastating economic effects on producers, but also can result in a variety of socio-economic impacts on surrounding communities. It would, therefore, be prudent to implement strategies for the prevention of TiLVD and to develop contingency plans to eradicate, contain, and mitigate the impacts of the disease when outbreaks occur. This manual provides information on: 1) the nature of TiLVD; 2) diagnosis; 3) prevention and control; 4) epidemiology; 5) principles of eradication, containment and mitigation; and 6) policy development issues.
Anaerobic Digestion - Making Biogas - Making Energy
Hundreds of million tonnes of agricultural and food waste are produced each year around the world, most of which is just that, waste. Anaerobic digestion, biogas and the heat and electricity that can be produced from it is still a nascent industry in many countries, yet the benefits of AD spread throughout the community: Gives good financial returns to farmers and eco-entrepreneurs. Helps community leaders meet various policies and legislative targets. Offers an environmentally sensitive waste disposal option. Provides a local heat and power supply, & creates employment opportunities Reduces greenhouse gas emissions, as well as providing an organic fertilizer. Although the process of AD itself is relatively simple there are several system options available to meet the demands of different feedstocks. This book describes, in simple, easy to read language the five common systems of AD; how they work, the impact of scale, the basic requirements, the costs and financial implications, and how to get involved in this rapidly growing green industry.
