“…The generated results showed that temperatures between 20 • C and 25 • C accounted for the highest methane emissions at a biochemical methane potential (BMP) of 69.3% and 50.3%, respectively [46]. Ma et al [47] investigated the impact of manure storage methods that involved exporting pig slurry to outside storage locations on methane and ammonia emissions levels. The generated results showed that frequent export of slurry to external storage led to more ammonia emissions and lower methane emissions [47].…”

“…Ma et al [47] investigated the impact of manure storage methods that involved exporting pig slurry to outside storage locations on methane and ammonia emissions levels. The generated results showed that frequent export of slurry to external storage led to more ammonia emissions and lower methane emissions [47]. Such insights indicated that delaying the residence periods of the pig slurry within the in-house storage led to the reduction of the total methane emissions that were generated.…”

“…The discussion of [45][46][47] underscores the importance of temperature and a long duration of time for storing livestock manure in order to maximize the emissions generated. The insights also established that longer storage periods for the livestock slurry would also result in higher methane and ammonia emissions from the manure.…”

Livestock Agriculture Greenhouse Gases for Electricity Production: Recent Developments and Future Perspectives

The focus of this review paper was to investigate innovations currently employed to capture and use greenhouse gases produced within livestock farms for energy production and expected future directions. The methods considered for data collection regarded a systematic review of the literature, where 50 journal articles were critically reviewed. The main findings identified that the conventional method used in transforming livestock agriculture greenhouse gases into energy regards the combustion of biogas. However, emerging methods encompass microbial fuel cells, dry biogas reforming, steam biogas reforming, auto thermal Chemical Looping Reforming (CLRa), and gas-to-liquid methods that convert methane to liquid hydrocarbons. The conclusions from the review are that there is a potential to integrate these methods in livestock agriculture in order to generate energy from greenhouse emissions and reduce the reliance on fossil fuels.
