Book excerpt: Although animal manures are traditionally viewed as a valuable resource material, there is also a risk for adverse environmental effect from manure generation and utilization. Research was conducted into impacts of common liquid dairy manure storage practices in Canada on methane emissions as well as nutrient composition changes during storage. Further investigation evaluated liquid dairy manure as feedstock for biogas production along with off-farm organic waste. During 17-month continuous on-farm monitoring of stored liquid dairy manure CH4 fluxes varied diurnally, monthly and seasonally, the variability largely regulated by measured internal manure temperatures, particularly at 2 m depth. Peak fluxes occurred in summer and fall seasons, increasing from July to September, falling in October and November, and remained constantly minimal from December to June. From September 2010 to August 2011, 85% of CH4 emissions occurred in summer and fall while 15% took place during winter and spring. Estimated emissions using IPCC methodology varied between months by 357% below to 88% above measured emissions, but on an annual basis the measured emission were 3.8% higher than the IPCC estimate. Monitoring of changes in manure composition during 12-month manure storage showed temporal changes and high variability in volatile solids (VS), chemical oxygen demand (COD) and volatile fatty acid (VFA) contents. These changes reflect biological activity levels that were a function of location within the tank and depended on meteorological factors such as temperature and precipitation. Nitrogen losses amounted to 0.32%-0.35% TKN per day or about 10% per month. Biochemical methane potential (BMP) assay of liquid Dairy manure (LDM) in co-digestion with poultry manure (SPM) and dissolved air flotation waste (DAF) showed maximum specific CH4 yield (SMY) of 0.40 L g-1 VS from a mixture with about 10% DAF along with 40% VS of LDM and 50% SPM. Observed reduced biogas production at higher levels of DAF and SPM was likely due to high ammonia (NH3) or VFA content. Study results underline that manure storage condition and duration affect emissions of greenhouse gases as well as losses of nutrients from stored manure. Improved manure storage conditions therefore have the potential to enhance value of the manure resource and limit environmental impacts from its management and use.

This book was released on 2021-07-27 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced Technology for the Conversion of Waste into Fuels and Chemicals: Volume 1: Biological Processes presents advanced and combined techniques that can be used to convert waste to energy, including combustion, gasification, paralysis, anaerobic digestion and fermentation. The book focuses on solid waste conversion to fuel and energy and presents the latest advances in the design, manufacture, and application of conversion technologies. Contributors from the fields of physics, chemistry, metallurgy, engineering and manufacturing present a truly trans-disciplinary picture of the field. Chapters cover important aspects surrounding the conversion of solid waste into fuel and chemicals, describing how valuable energy can be recouped from various waste materials. As huge volumes of solid waste are produced globally while huge amounts of energy are produced from fossil fuels, the technologies described in this comprehensive book provide the information necessary to pursue clean, sustainable power from waste material. Presents the latest advances in waste to energy techniques for converting solid waste to valuable fuel and energy Brings together contributors from physics, chemistry, metallurgy, engineering and the manufacturing industry Includes advanced techniques such as combustion, gasification, paralysis, anaerobic digestion and fermentation Goes far beyond municipal waste, including discussions on recouping valuable energy from a variety of industrial waste materials Describes how waste to energy technologies present an enormous opportunity for clean, sustainable energy

Available in PDF, EPUB and Kindle. Book excerpt: 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.
