Bill Gates is investing in an Australian startup focusing on reducing methane emissions from cows through a lab-grown feed additive, with the company planning to use the funds for commercial trials and setting up manufacturing, even as experts question the practicality of methane-focused scientific pursuits.
Gates-led Breakthrough Energy Ventures LLC (BEV) was part of a $12 million phase-2 seed funding for Perth-based Rumin8, which is developing a livestock supplement made from synthetically replicated bromoform, which is the active ingredient found in red seaweed. The supplement is said to result in less gas and indigestion among cows, thereby lowering methane emissions.
Methane Emission Cycle
Meanwhile, some experts warn against too much focus on combating methane emissions. In a write up at The Epoch Times in November, Peter Castle, who has broad experience in the oil and gas, energy, and other process industries, warns that measures to combat methane emissions in activities like agriculture can “outweigh the benefits.”The half-life of methane is estimated to be roughly 10 years. Around 600 million tons of methane are produced and consumed annually, he notes.
“The methane produced by cattle, for example, comes from carbon in the food they eat, which in turn comes from carbon dioxide in the atmosphere. When that methane again breaks down in the atmosphere, it has returned to its original source,” Castle writes.
“It is consequently an overstatement to consider cattle emissions ‘anthropogenic’ since it has been happening for all of known history.” Anthropogenic is an adjective that refers to changes in nature as a result of human activity.
Reducing Methane Emissions in Cows
Rumin8’s product is made from naturally occurring compounds that are said to have anti-methanogenic properties.The product reproduces the bioactive contained in red seaweed called bromoform that can disrupt the enzymes of gut microbes which exist in the animal’s stomach. These microbes are responsible for generating methane gas during the digestion process.
The bioactive compound has been shown to cut down methane production in livestock rumen by up to 95 percent.
The phase-2 funds will be used for commercial trials in Australia, United States, Brazil, and New Zealand. By the middle of 2023, Rumin8 plans on establishing a pilot plant capable of producing 25,000 doses of its product per day.
“Rumin8 offers a low-cost, scalable toolbox that has already proven to be effective in reducing emissions. Our team will support Rumin8 in working closely with farmers to expand the reach of this solution globally.”
Multiple other firms have announced measures to cut down methane emissions from their business practices. Last week, for example, French food giant Danone said that it will change the way its cows are raised and milked, vowing to cut down methane emissions by 30 percent by 2030.
