Abatement Techniques For Reducing Emissions From Livestock Buildings

This book identifies future scientific research priorities for developing emissions inventories, emissions abatement techniques and mitigation strategies in order to improve and sustain livestock production that is in line with climate change adaptation. Livestock production is a major source of atmospheric pollutants and greenhouse gases, such as methane, nitrogen oxides, carbon dioxide and ammonia, all of which directly contribute to global warming and climate change. Air pollutant emissions from agricultural practices have a negative environmental impact and are of relevant political importance, as highlighted in both the Kyoto and Gothenburg Protocols. This book provides solutions on how to abate these emissions by using effective abatement techniques such as additives, manure storage covers, aerobic and anaerobic treatments, and dietary manipulation. Each chapter in the book provides valuable, up-to-date information on abatement techniques, thus allowing the reader to better understand the issues involved. Recent advances and new perspectives in the field are also discussed.

Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

The current analysis was conducted to evaluate the potential of nutritional, manure and animal husbandry practices for mitigating methane (CH4) and nitrous oxide (N2O) - i.e. non-carbon dioxide (CO2) - GHG emissions from livestock production. These practices were categorized into enteric CH4, manure management and animal husbandry mitigation practices. Emphasis was placed on enteric CH4 mitigation practices for ruminant animals (only in vivo studies were considered) and manure mitigation practices for both ruminant and monogastric species. Over 900 references were reviewed; simulation and life cycle assessment analyses were generally excluded

Air quality has a direct influence on health, welfare and production performance of livestock as the high concentrations of noxious gases, dust and airborne microorganisms are likely to reduce production efficiency and the general welfare of farm animals. Long term exposure to particulates in livestock buildings might also affect the respiratory health of farm workers. Dust in animal buildings contains many biologically active substances such as bacteria, fungi, endotoxins and residues of antibiotics (as a result of veterinary treatments) that are suspected to be hazardous to human health. Furthermore, air pollutants emitted from livestock buildings can reduce air, water and soil quality and can potentially undermine the health of nearby residents. Airborne emissions include ammonia, methane, nitrous oxide, particulates like dust and microorganisms. In addition, other potentially harmful substances such as heavy metals, antibiotic residues and components of disinfectants might be also emitted from livestock building that are potentially damaging to ecosystems. In this book, key aspects of agricultural air quality, such as monitoring, managing and reducing airborne pollutants in and around livestock facilities are reviewed. Features: addressing the raising awareness of the importance of optimal health and welfare for lifestock species with contributions from international specialists and researchers providing up-to-date information for professionals involved in modern animal producti This book will be useful for farming professionals, academics, students, policy makers, business leaders, regulatory bodies and agricultural consultants.

"Ammonia emissions is an important topic in many countries with animal production, since it contributes to environmental and health problems. Strategies and measures to reduce ammonia emission are getting increasing attention in national and international legislation. This book aims to bring together visions and knowledge from scientists, policy makers and other relevant stakeholders around the subject of NH3 emissions from agricultural operations and its reduction options. It also offers a basis for international harmonization on various NH3 emission related topics (e.g. national emission inventories, measurement techniques and strategies, data on emissions and reductions) and, last but not least, it provides an update of science concerning NH3 and related environmental issues. The focus of this publication is on NH3 emissions from various agricultural sources (grazing, animal housing, manure storage, land application of manures), and the options for their reduction in a farm system approach. Also, multiple gaseous emissions, their reduction options and pollution swapping issues are addressed. Environmental impact and health related effects of NH3 are briefly addressed. In conclusion, this book gives an overview of the current knowledge about ammonia emissions and how we can implement this knowledge in current agricultural systems."

Understanding greenhouse gas sources, emissions, measurements, and management is essential for capture, utilization, reduction, and storage of greenhouse gas, which plays a crucial role in issues such as global warming and climate change. Taking advantage of the authors' experience in greenhouse gases, this book discusses an overview of recently developed techniques, methods, and strategies: - A comprehensive source investigation of greenhouse gases that are emitted from hydrocarbon reservoirs, vehicle transportation, agricultural landscapes, farms, non-cattle confined buildings, and so on. - Recently developed detection and measurement techniques and methods such as photoacoustic spectroscopy, landfill-based carbon dioxide and methane measurement, and miniaturized mass spectrometer.

Ce rapport aborde les sources d'émission d'ammoniac, leur impact sur l'environnement, sur le cycle et l'utilisation de l'azote dans les sols ainsi que sur la santé humaine et animale. Il synthétise les travaux de recherche réalisés pour développer et évaluer des techniques de réduction des émissions d'ammoniac.

Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
