TL;DR: In this article, the authors evaluated the effects of AD, SLS, and AD+SLS on GHG and NH3 emissions during manure storage through land application over nine months and found that AD and SLS alone significantly reduced total GHG emissions for storage and land application compared to untreated manure slurries by 25% and 31%, respectively.

Livestock and climate change: impact of livestock on climate and mitigation strategies.
TL;DR: The objectives of this manuscript are to discuss the main greenhouse gas emissions sources from the livestock sector and summarize the best mitigation strategies aimed at reducing emissions of this sector.
Greenhouse gas emissions from inorganic and organic fertilizer production and use: A review of emission factors and their variability.
Eric Walling,Céline Vaneeckhaute +1 more
TL;DR: It is recommended to determine emission factors (EFs) on a case by case basis when possible and to use uncertainty analyses as a tool to better understand the impact of EF variability.

TL;DR: This study presents a comprehensive life-cycle assessment of competing management alternatives for organic municipal solid waste including landfilling, composting, dry anaerobic digestion (AD) for the production of renewable natural gas (RNG), and dry AD with electricity generation.

TL;DR: In this article, the authors show that environmental and health life cycle impacts are often lower for phosphorus fertilizers sourced from secondary raw materials than for rock-phosphate-derived products, especially in areas of high livestock and population density.

Economic analysis of electrodialysis, denitrification, and anammox for nitrogen removal in municipal wastewater treatment
TL;DR: In this paper, the authors compared the state-of-the-art of municipal nitrogen removal to the new electrodialysis technique on an economic basis, and found that nitrogen removal and recovery by electRodialysis is estimated to lower both initial capital costs and subsequent operation costs than traditional N removal technologies.

The role of carbon dioxide in emission of ammonia from manure
TL;DR: In this paper, a model of simultaneous NH3 and CO2 emission was presented, which includes equilibrium acid/base reactions, kinetically-limited CO2 hydration/dehydration reactions, and diffusive transport.
Ammonia and nitrous oxide interactions: Roles of manure organic matter management
Søren O. Petersen,Sven G. Sommer +1 more
TL;DR: McAllister et al. as discussed by the authors proposed a model that accounts for the complex interactions between C and N transformations at each stage of the manure management chain in a time scale that is relevant for management practices such as retention time in housing and storage, treatment to optimize nutrient management, and timing of field application.
From waste-to-worth: energy, emissions, and nutrient implications of manure processing pathways
TL;DR: In this paper, four manure processing pathways are evaluated to provide a system-level understanding of their impacts on different sustainability indicators, including depletion of fossil fuels, nutrient balances, global warming potential (GWP), and ammonia emissions when compared to the base case (BC) pathway of direct land application.
Quantifying the Reduction of Greenhouse Gas Emissions as a Resultof Composting Dairy and Beef Cattle Manure
TL;DR: In this paper, greenhouse gas emissions from three methods of storing dairy and beef cattle manure were compared during the summer period using a flowthrough closed chamber, and the largest combined N2O−CH4 emissions in CO2 equivalent were observed from the slurry storage, followed by the stockpile and lastly the passively aerated compost.
