Scientists prove a specific species of red algae added to cow droppings significantly reduces methane emissions from stored feces.
AT, a red algae species in tropical to warm waters, has a cosmopolitan distribution. Its primary compound, bromoform, serves as a potent methane inhibitor, impeding gas generation. AT is currently the most promising natural solution for mitigating methane emissions.
Supplementing cows' feed with AT has potential drawbacks due to its elevated iodine levels, which can lead to increased iodine concentrations in milk consumed by humans. The impact of manure on greenhouse gas emissions varies depending on factors like how it is stored. In the cool-temperate European climate, manure storage accounts for roughly 12 percent of total methane emissions from the dairy system.
