Summary: This study reveals that despite significant success in capturing CH4 and carbon dioxide as biogas and preventing N2O emissions, gains made can be lost in a subsequent process, negating some or all of the advantage. Additionally, the process of extracting value from the captured resource is discussed in light of current farm parameters together with indications of other potential revenue streams.

Summary: A new method to reduce CH4 emissions from farm dairy effluent by up to 99% has been discovered through treating FDE with PFS. This treatment also resulted in a reduction of CO2 emissions by approximately 50% and a decrease in hydrogen sulfide emissions. However, there was a slight increase in nitrous oxide emissions, though they were low and only accounted for <3% of the total CO2-e greenhouse gas emissions from the treated FDE.

Summary: The study investigates the impact of intensified farming practices on the energy production for water heating in New Zealand low-input dairy farms. A combination of methods including literature review, surveys, chemical analyses, biomethane potential analysis, and modeling were used. Results showed that 558 MJ/day and 176-861 MJ/day of energy could be produced from the solid and liquid portions of effluent, respectively, which would be sufficient for water heating needs of a dairy farm using a tankless water heater.

Summary: The study found that applying dairy effluent significantly increased ammonia emissions during the wheat season, but had no discernible impact on N2O emissions compared to inorganic fertilizer. However, the greater application of effluent led to a significant increase in NO emissions. The combined application of manure and urea reduced N2O and NO emissions, but increased NH3 emissions during the wheat season.

Summary: The research results indicate that residual slurries of acidified manure become poor inoculants in subsequent storage, hence manure acidification has a long-term treatment effect in reducing CH4 production.

Summary: This study investigated the effects of alfalfa-derived biochar (AF-BC) on anaerobic digestion (AD) of dairy manure. The results showed that the addition of AF-BC in appropriate amounts significantly increased biogas and methane yields, reduced COD and CO2 content, and improved AD performance. However, excessive addition of AF-BC may have toxic effects on AD microorganisms.

Summary: This study compared the effects of broadcast and low disturbance manure incorporation on alfalfa yield, ammonia, and nitrous oxide fluxes, highlighting the relationship between manure application and precipitation events on N2O fluxes. The results emphasize the importance of quantitatively evaluating agri-environmental tradeoffs to determine the optimal manure application method.

Summary: The study found that the addition of Co nanoparticles can improve the hydrolysis rate of anaerobic digestion of cow dung, and the fertilizer efficiency of the effluent with Co nanoparticles is comparable to that of commercial NPK compound fertilizer.

Summary: Methane emissions from liquid manure management in Canada are a significant contributor to greenhouse gas emissions. This study highlights the importance of using regional methane conversion factors that account for climate and management variations in order to accurately estimate methane emissions. The efficiency of manure removal and climate variations have a significant impact on methane emissions, and improving management practices can help reduce these emissions.

Summary: In this study of anaerobic digestion of chicken manure with varying chlorotetracycline concentrations, it was found that extracellular polymeric substances (EPS) play a protective role against chlorotetracycline by forming complexes to decrease degradation and increase adsorption. However, there is also a potential risk to the soil ecosystem from the adsorbed chlorotetracycline on EPS in sludge.

Summary: This study provides a comprehensive analysis of the magnitude, spatiotemporal variation, and drivers of nitrous oxide emissions from Chinese livestock production over the past four decades. The study highlights the decline in growth rate of livestock N2O emissions from 2007 to 2015 and estimates the potential and costs of reducing these emissions by 2030. The findings also identify priority regions for intervention and the most effective mitigation options.

Summary: High-rate algae ponds can effectively combine wastewater treatment with biomass production for biofuel. However, the presence of algae in HRAPs can negatively impact pathogen removal. Factors such as high pH, dissolved oxygen levels, and mixing can enhance sunlight-mediated pathogen removal. Predation may also play a role, but further research is needed to understand its quantitative impact.

Summary: This study aimed to verify the occurrence and significance of dark decay, alkaline-pH toxicity, and sunlight direct damage in High Rate Algal Ponds (HRAPS) during wastewater treatment. Data from monitoring Escherichia coli cell count in pilot HRAPs were used to create a model for E. coli removal prediction. The model predicted that dark decay had the highest yearlong mean contribution to E. coli removal in HRAPs, followed by sunlight mediated disinfection and pH toxicity.
