Book Description
A rapidly changing and expanding livestock and poultry production sector is causing a range of environmental problems on local, regional and global scales. Animal Manure Recycling: Treatment and Management presents an accessible overview of environmentally friendly technologies for managing animal manure more efficiently and in a sustainable manner. The book describes the physical and chemical characteristics of animal manure and microbial processes, featuring detailed examples and case studies showing how this knowledge can be used in practice. Readers are introduced to the sustainable use of animal manure for crop fertilisation and soil amelioration. Environmentally friendly technologies for reducing emissions of ammonia, odour and the greenhouse gases nitrous oxide and methane are presented, and reduction of plant nutrient losses using separation technologies is introduced. Finally and most importantly, the book describes methods to commercialise and transfer knowledge about innovations to end-users. Topics covered include: Regulation of animal manure management Manure organic matter: characteristics and microbial transformations Greenhouse gas emissions from animal manures and technologies for their reduction Technologies and logistics for handling, transport and distribution of animal manures Bioenergy production Animal manure residue upgrading and nutrient recovery in bio-fertilisers Life cycle assessment of manure management systems Innovation in animal manure management and recycling Animal Manure Recycling: Treatment and Management presents state-of-the-art coverage of the entire animal manure chain, providing practical information for engineers, environmental consultants, academics and advanced students involved in scientific, technical and regulatory issues related to animal manure management.

Book Description
Manure management contributes 8.4% of anthropogenic methane emissions (USEPA, 2015). It is extremely likely that greenhouse gas emissions including methane are correlated to an increase in global temperatures and sea level over the past century. Additionally, livestock contributes and estimated 71% of ammonia emissions and ammonia is a precursor to particulate matter which can decrease visibility and affect human health (Roe, Spivey, Lindquist, Thesing, & Strait, 2004). Therefore, to reduce future long term environmental and health complications it crucial that gaseous emissions from the production dairy are reduced. Experiments were conducted to evaluate potential mitigation strategies to reduce greenhouse gas (GHG) and ammonia (NH3) emissions from dairy manure. Results from the first experiment on the impacts of manure processing on GHG and NH3 from the storage and land application of dairy manure revealed that anaerobic digestion (AD) and solid liquid separation (SLS) significantly reduce GHG emissions. AD and SLS reduced GHG from untreated manure slurries by 34% and 22%, respectively; however, AD increases NH3 emissions by 81%. A second experiment quantified the impacts of manure additives, including More Than ManureTM (MTMTM), Pro-Act, and biochar, on manure solids, gaseous nitrogen losses, and GHG emissions. No treatments were able to reduce manure solids or gaseous nitrogen losses. Biochar was the only manure treatment to impact any manure characteristics, where the total ammonical nitrogen (TAN) was significantly greater than the control at day 14 (p=0.012). In a third experiment, raw wood (white birch, Betula papyrifera), steam treated wood, wood biochar, and corn cob biochar were investigated for their potential to reduce NH3 emissions from digested manure storages. In order to guide application strategies and better understand the mechanisms for mitigation, treatments were incorporated in the manure or applied as a cover and the TAN sorption was measured using extraction techniques. All biomass treatments reduced emissions of NH3 from the control by 40% to 96%. The highest NH3 emissions reductions were achieved with the wood biochar cover due to its ability to effectively cover the manure. Sorption results indicate that only a very small portion of the biomass mitigation potential was due to sorption and the main mechanism for NH3 reduction was the ability to act as a physical barrier. Future research should assess the GHG and NH3 reduction potential of coupling AD, SLS, and a biochar cover in a long term field trial.

Book Description
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

Book Description
The time when agricultural production activities were considered neutral to the environment has definitely passed. For last 25 years there has been growing scientific evidence on the potentially deteriorating effect of ammonia released in the process of agricultural production on the environment. In the last 15 years additional focus has been given to environmental and health impact of dust and VOC’s generated by farming activities. Only very recently is the contribution of agricultural production GHG’s to global warming recognised. In the book the various aspects of agricultural emissions are discussed. Its first part refers mainly to introductory, theoretical, and methodological issues. The second part gives the most recent data on national emissions, particularly these of Nitrogen species in selected individual European countries and the projections of their emission for all Europe. The third part which deals exclusively with ammonia brings comprehensive survey of its emission abatement potentials, the cost of appropriate actions and the difficulties in their practical implementation. It also considers the potential side effects of ammonia emission abatement measures.

Book Description
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.
