No bull!@#$: Number 8 Bio lands $1.8 million for animal feed that reduces cow farts

Biotech startup, Number 8 Bio, has just raised $1.8 million in pre-seed funding for its proprietary feed that reduces methane emissions in cows.

The round saw participation from CSIROโ€™s Main Sequence โ€” the deep tech fund founded by CSIRO, Possible Ventures, UNSW Founders, and Bioplatforms Australia. According to Number 8 Bio, the fresh cash injection will be used to accelerate R&D as well as expand its lab capabilities.

Weโ€™ve certainly seen a trend towards investment in emission reduction startups of late. Back in November, Perth startup ULUU raised $8 million for its seaweed-based alternative to plastics.

And there must be something going on in WA because another Perth startup, Rumin8  landed over $17 million in January for its own methane-reducing feed. This was led by Breakthrough Energy Ventures, which is headed up by Bill Gates.

And thereโ€™s a reason why this is a particular point of concern right now. Ruminant animals, such as cows, are the largest agricultural source of greenhouse gas globally.

While ULUU uses fermentation methods to create a plastic alternative out of seaweed, Number 8 Bio has found a way to bioengineer naturally occurring yeasts to make a feed additive that reduces methane emissions and, according to the business, is scalable.

โ€œWhat we do is engineer microorganisms like yeast which can be grown all around the world at multi-millilitre leader scale. You can make tons of yeast in a couple of days in a pretty standard facility,โ€ Tom Williams, CEO and co-founder of Number 8 Bio said in a call with SmartCompany.

โ€œAnd we have those organisms produce the active molecules that decrease methane emissions from ruminants, and then the yeast cells are dried and included in the diet as an additive.โ€

And the numbers are impressive. According to Williams, on a per-animal basis, they expect a greater than 90% decrease in emissions when the molecules are delivered at the right concentration.

โ€œBut perhaps more importantly, weโ€™re really looking at locking in increased feed conversion efficiency. If you can stop those methane emissions, thereโ€™s actually more of the food available for the animal to grow and produce things like wool and meat and milk,โ€ Williams said.

Having only been founded a year ago, the business is still in the R&D phase โ€” including taking feedback from farmers. At the beginning of next year, it plans on conducting live animal trials with its feed.

When it comes to commercialisation, Australiaโ€™s ingrained farming culture, as well as pivots towards sustainable practices โ€” and investment despite economic downturns โ€” makes it a great market to launch in.

โ€ Itโ€™s a really favourable environment for products like this. Thereโ€™s a big marker pull from retailers looking to implement climate-friendly labeling on animal products and the regulations here are really favorable for products like this as well,โ€ Williams said.

โ€œBut weโ€™re actually also looking to simultaneously commercialise in the U.S. Weโ€™ve actually got a subsidiary set up there already and an employee in California.โ€

Williams also saw a gap when it comes to the focus of businesses on climate tech.

โ€œMost tech companies are trying to replace agriculture with alternative proteins and plant-based meats. Whereas I canโ€™t see animal-based agriculture disappearing anytime soon,โ€ Williams said.

โ€œI really value that part of society, itโ€™s the foundation of civilisation.โ€
