We are decreasing agricultural methane emissions
About Alga Biosciences
Alga Biosciences, operating from its base in Berkeley, California, is focused on mitigating methane emissions from the agricultural sector, specifically from cattle. The company is developing a seaweed-based feed supplement designed to significantly reduce the methane produced by cows during their digestive process. This positions Alga Biosciences within the growing climate tech and sustainable agriculture markets, addressing the substantial environmental impact of livestock, which is responsible for approximately 6% of global greenhouse gas emissions. The primary clients for this product are beef and dairy producers who are facing increasing pressure to adopt more sustainable practices. The business model appears to be centered on the production and sale of this feed additive directly to farms and feedlots. The company was founded in 2022 by a team with diverse and relevant expertise. D. S. Lee, one of the co-founders, brings a background in venture capital from his time at an early-stage climate tech fund, providing strategic financial acumen. Another co-founder, Supratim Ghosh, contributes deep scientific knowledge with a Ph.D. in Chemical and Biomolecular Engineering from the University of Illinois Urbana-Champaign and experience from research institutions like the Lawrence Berkeley National Laboratory. Tsubasa Lagarde, also a co-founder, has a background in materials science and engineering. This blend of financial, scientific, and engineering experience underpins the company's approach to tackling agricultural methane emissions.
