Company Overview
About Alga Biosciences
Alga Biosciences is a climate biotechnology company developing seaweed-based feed supplements that reduce methane emissions from cattle and other ruminant livestock. Cattle and sheep emit methane through enteric fermentation — a digestive process where microbes in the rumen produce methane as a byproduct of breaking down plant material. Enteric fermentation from livestock accounts for approximately 4% of global greenhouse gas emissions (as methane is ~80x more potent than CO2 over 20 years), making it one of the largest targets for agricultural decarbonization.
Business Model & Competitive Advantage
Alga Biosciences has focused on developing a commercially viable, stable, and effective alternative to Asparagopsis (a red seaweed shown in trials to reduce cattle methane by 50–80% when fed in small amounts), which has faced challenges in large-scale production and palatability. The company uses synthetic biology and fermentation to produce the active compound (bromoform) at scale and stability levels suitable for commercial feed use. This biotechnology approach aims to provide the climate benefit of natural seaweed compounds without the supply chain challenges of harvesting wild Asparagopsis at the scale needed for the global cattle industry.
Competitive Landscape 2025–2026
The livestock methane supplement market is nascent but potentially enormous: hundreds of millions of beef and dairy cattle globally represent a massive climate intervention opportunity if effective, low-cost supplements can be commercialized. Alga Biosciences is one of several companies (along with 3NitroStearic Acid maker Arkeabio, Rumen Nitrification products, and others) racing to develop the first widely adopted livestock methane reducer.
