Latest research have discovered that utilizing seaweed to feed livestock may considerably scale back the quantity of methane cows produce. One of many weeds that has been fronted for this function is the pink seaweed Asparagopsis taxiformis. The weed has been used to develop a cow feed additive often known as Brominata.

Brominata was developed by Straus Household Creamery, an natural dairy farm in Marine County, California. The farm made headlines final fall when it began testing the weed to see whether or not it may assist scale back the output of their animals. The trials had been profitable, with the additive main as much as a 52% discount in enteric methane emissions. In a single cow, methane gasoline manufacturing was lowered by as much as 92%. This is a sign that the additive could possibly be scaled to considerably scale back methane launch in cows.

Though the share of methane within the ambiance is far smaller in comparison with C02, methane gasoline is extra damaging to the setting. Methane gasoline solely makes up 0.00017% of atmospheric gases, nevertheless it traps as much as 80 occasions extra warmth than CO2 over a 20-year interval.
“My imaginative and prescient and purpose is to show that [dairy farms] are an asset to the neighborhood. It’s about having the ability to present that livestock have an vital position sooner or later,” mentioned Albert Straus, founding father of Straus dairy farms.
One cow belches out about 220 kilos of methane yearly. That’s equal to burning 900 gallons of gasoline. With the large variety of cows farmed in areas similar to California, the long-term outcomes of farming could be devastating to the ambiance.
A California Air Sources Board report launched in March categorized seaweed components in animal feeds as one of many key methods to assembly dairy-based greenhouse targets. Whereas seaweed components have been fronted as one of many attainable farming-based methane polution options, there are a lot of challenges.
The largest downside with using seaweed components has been the power of manufacturing. As is the case with many local weather options, seaweed processing additionally consumes quite a lot of power. This has brought on many issues in regulatory approvals for many merchandise.
Consultants say that California nonetheless has a protracted method to go within the quest to chop dairy carbon emissions by half on the finish of this decade. Nevertheless, the report exhibits that there’s progress in the best route.
