Solution Pitch

The Problem

During a cow’s digestive process, bacteria in their gut decomposes food and produces methane as a by-product. Through this process, called enteric fermentation, cows and other livestock create 30 percent of man-made methane emissions, contributing as much to global warming as the entire European Union.

The Solution

Symbrosia’s solution is to add a small amount of a single species of seaweed to livestock feed to create a large reduction in methane emissions. Symbrosia’s novel livestock feed supplement is made from a species of red seaweed called Asparagopsis taxiformis (A. taxiformis). Research from The Commonwealth Scientific and Industrial Research Organisation, Penn State, and UC Davis have shown that replacing just 0.4 percent of a cow’s feed with A. taxiformis reduces the amount of methane the cow produces by over 90 percent. On a molecular level, A. taxiformis inhibits hydrogen and carbon dioxide from combining to form methane in a cow’s stomach. 

Using an innovative, on-land aquaculture production system, Symbrosia grows A. taxiformis at scale and powederizes it to create the sustainable feed product SVD. The cows, sheep, and goats that consume it don’t even notice that they are helping save the planet.

Market Opportunity

Despite the proliferation of plant-based meat products, Americans ate more meat in 2018 than ever before. Worldwide, as hundreds of millions of people rise out of poverty, they are consuming more meat. In the United States alone, there are over 1.3 million livestock farms, and at least 1.3 billion people worldwide depend on livestock for their livelihoods. Governments—including the EU, multiple US States, and New Zealand—are pursuing taxes on agricultural methane emissions to combat climate change. However, livestock farmers, who are already facing price drops caused by the COVID-19 pandemic, currently have no way to significantly lower their emissions. The annual market share for Symbrosia’s sustainable supplement in the US alone is $10 billion at target pricing per kilogram of material.

Organization Highlights

  • First commercial trial with Asparagopsis taxiformis algae on ruminants

  • NSF SBIR Phase I awardee

  • 50 to Watch company by the CleanTech Group

Partnership Goals

Symbrosia currently seeks: 

  • Advisory for biotech commercial demonstration facility commissioning and readiness level

  • Medium-sized beef and dairy producers with interest in increased operational sustainability (US or LATAM)

  • Livestock industry product development partnerships (Marketing and R&D)

Stats 

Symbrosia’s novel livestock feed supplement has already reduced 4 ton CO2-eq emitted by livestock to date

Who does your solution serve, and in what ways will the solution impact their lives?
Our solution serves large-scale livestock farmers, first in the USA and then worldwide. These farmers face persistent financial pressure from low margins, rising input costs, and growing regulatory exposure around livestock methane emissions. We are developing SeaGraze® in close partnership with farmers, ensuring it is understandable, accessible, and wanted by the people using it. We received funding from the USDA's Sustainable Agriculture Research and Education division to work with Z Farms Organic, collaborating closely with the farm's owner, Dr. Diane Zlotnikov, throughout a pilot that began in June 2020. The impact is tangible. Consumer research with 300+ organic dairy consumers in the Northeastern United States found they would pay $1.50–$2.00 extra per gallon for "methane-neutral" milk — a meaningful revenue uplift that goes directly to farmers. SeaGraze® also positions farmers to get ahead of regulatory risk and access emerging carbon markets. We are making profitability and sustainability the same goal.
