Number8Bio® | Decarbonising the planet with synthetic biology

We’re not reinventing food or agriculture, but we’re eliminating the emissions.

The ruminant in the room.

As the global population grows, so to does the demand for meat and dairy products. That of course means we need more livestock, which are notorious methane producing machines, currently contributing up to 15% of global greenhouse gasses.

A number set to go up with demand, and worse still these methane emissions are about 28 times more effective at trapping heat than carbon dioxide over a 100-year period.

The alternative protein industry is trying to reinvent food, but can’t scale to meat demand.

Alternative proteins are not being adopted by consumers at a rate that will meet 2030 emissions reductions targets. We are aimed at having a massive positive impact, without requiring consumer behavior change.

Government & regulators are demanding change.

Governments are creating policy faster than solutions can get to market. We are working with farmers to get our product into their hands, so that they don't have to cut production to meet regulations.

One small change could change everything.

By adding as little as 0.5% of our BetterFeed additive to cattle feed we could reduce ruminant methane by up to 98%.

Our mission is to decarbonise agriculture and feed our growing population. We can achieve this by harnessing the power of trillions of carbon-hungry microbes that feed on damaging greehouse gasses and convert that pollution into valuable animal feeds. We're changing feed, to feed change.

Our impact can be felt beyond just food.

Scalable, till the cows come home.

Microbes are the key to our affordability and effectiveness. They are already grown safely all over the world at enormous scale. We don't need to grow novel seaweed farms to bring our product to market.

Just one fermentation plant...

...can produce enough feed to supply Australia's...

and California’s entire dairy and feedlot.

Made with farmers,
for farmers.

We've worked with farmers to build a product that gives them what they want. It doesn't harm animals, is affordable, creates consistent productivity gains, and can be delivered easily. We call it BetterFeed™.

Good people, doing good work with real impact.
