| Rumin8 is tackling one of the biggest contributors to climate change: methane emissions from livestock. The digestive process of beef and dairy cattle accounts for a full 3.7% of all greenhouse gas emissions, a huge contribution from a single source. With billions of people around the world relying on animal proteins as part of their daily diet,eliminating livestock methane production is a powerful lever in the quest toward a climate-optimal future.Rumin8 has invented a technology that has been shown to reduce the emissions from cattle by up to 95%. Our technology productizes the anti-methane compounds that occur naturally in plants and turns them into dietary supplements for livestock. The results are a reduction in methane emissions by up to 95%, increase in efficiency of the animal’s digestive systems, and more energy for the animal to growWe are on a mission to decarbonize hundreds of millions of cattle around the world so the global food system can take a giant step forward. | $3M / Venture - Series Unknown / Mar 25, 2026 | ||
