Solving enteric fermentation with Performance Digestion.


What is enteric fermentation?

Enteric fermentation refers to the digestive process that occurs in the stomachs of ruminant animals such as cows, sheep, and goats. These animals have a unique digestive system that allows them to break down and extract nutrients from plant material, particularly cellulose, which is otherwise indigestible to most other animals.


During the enteric fermentation process, microorganisms in the animal's stomach produce methane gas as a byproduct, which is then expelled by the ruminant, mainly through belching.


Methane (CH4)


Methane is 80x more effective at trapping heat than carbon dioxide.


Global green house emissions from ruminant methane.

Methane is one of the most impactful GHG to mitigate as it degrades over 20-years.


The science of Performance Digestion.

Methane emissions are not only harmful to the environment, but they represent wasted nutrition in animal feed. Every molecule of methane belched into the atmosphere is energy that could otherwise have been utilised by the animal to produce meat, milk, or wool.

Our products are designed to consistently realise this productivity benefit through a process we call Performance Digestion.


Delivering change at a global scale.

Performance Digestion opens up exciting possibilities for innovation across various industries by harnessing the power of microorganisms to produce valuable and sustainable products at low cost and large scale.


At Number 8 Bio we're using Performance Digestion and Synthetic Biology to lead the path to a green agricultural revolution.


One = 4.7M

Just one production facility can produce enough BetterFeed additive to feed 4.7M livestock


From pollution to solution.

Through Performance Digestion we are using microorganisms capable of growing on organic waste. This biomass is fed to trillions of carbon-hungry microbes that turn waste into valuable feed and food ingredients.

This can reduce arable land use, cutting down on agricultural emissions significantly. Our solution is scalable and effective.

Good people, doing good work with real impact.


Helping deliver carbon negative food for everyone.
