A California-based biotechnology startup has officially launched the world's first commercially available butter made entirely from carbon dioxide, hydrogen, and oxygen, eliminating the need for traditional agriculture or animal farming. Savor, backed by Microsoft co-founder Bill Gates through his Breakthrough Energy Ventures fund, announced the commercial release of its animal- and plant-free butter after three years of development.

The revolutionary product uses a proprietary thermochemical process that transforms carbon dioxide captured from the air, hydrogen from water, and methane into fat molecules chemically identical to those found in dairy butter. According to the company, the process creates fatty acids by heating these gases under controlled temperature and pressure conditions, then combining them with glycerol to form triglycerides.

How much carbon is emitted to run the factory to make it though? Are we talking a net negative here?

[–] hamsterkill@lemmy.sdf.org 5 points 2 days ago (1 children)

Some, as prepping the carbon and hydrogen will take energy. But it wouldn't be hard to be way better than the emissions associated with dairy farming for butter. Cost could still be higher, though depending on how much material is needed for the process.

I wonder where they source the methane from. Because I pictured a comicbook flip book of a balloon blowing up behind a cow

[–] hamsterkill@lemmy.sdf.org 2 points 2 days ago (1 children)

Methane is just the primary compound in natural gas.

I mean they can get it from the ground, but it can also come from things kind of fermenting in cows/our stomachs.

I must be losing my mind because I thought I saw this post 2 days ago except it said beer.

Should be a nice change from that silicon based butter I usually get.

[–] ShittyBeatlesFCPres@lemmy.world 20 points 3 days ago (3 children)

I don’t eat carbon-based foods. Exotic silicon lifeforms, fresh from Titan’s methane seas.

[–] Blackout@fedia.io 15 points 3 days ago

How do you know when someone is a non-carbon eater? Don't worry they will tell you.

Oh look; AI has gotten so advanced that computers now have haut-quisine.

There's a term for that high-carbon butter-like substance. Migraine or something..

[–] partial_accumen@lemmy.world 19 points 3 days ago (1 children)

To put it in simple terms, Savor says they take carbon dioxide from the air and hydrogen from water, heat them up, oxidize them and get a final result that looks like candle wax but is in fact fat molecules like those in beef, cheese or vegetable oils.

So their process sounds like it creates synthetic lard, not butter. This can still be a good thing as the extra ingredients to make it "butter" aren't really the hard/impactful part of butter.

This is interesting...

Lab grown meat have problem where they cannot create fat. So if this works, maybe this is the solution.

"So you're using this gas right now to cook your food and we're proposing that we would like to first make your food with— with that gas," said Kathleen Alexander, co-founder and CEO of Savor.

That doesn't sound appetizing... Lol.

[–] NoForwardslashS@sopuli.xyz 9 points 3 days ago (1 children)

I would like to propose you eat my gas

[–] IllNess 9 points 3 days ago

"Eat my gas" should be their slogan.

I'd actually be willing to give it a try if it's vaguely price-competitive, but their website is all glam shots of butter and people doing things with butter and not only doesn't sell it but doesn't tell you where you can get it.

https://www.savor.it/

Also, they did not do a good job of choosing that name. It looks like there's a very-similarly-named French Canadian manufacturer of butter, Savör, which apparently isn't too religious about using their umlaut:

At Savor, we believe the best butter starts with the best environment. That’s why we source our grass-fed dairy butter from New Zealand, a country renowned for its pristine landscapes, sustainable farming, and exceptional dairy quality.

I foresee a collision between those two.

So, in essence, this, but with added marketing steps.

[–] _cryptagion@lemmy.dbzer0.com 2 points 2 days ago

I've heard that people made from carbon taste like the real thing too, you all should try it!

[–] UltraBlack@lemmy.world 1 points 2 days ago (2 children)

From the description I cannot in a million years assume that it tastes anywhere near butter. And where's the buttery taste going

"Fat molecules chemically identical to those in butter". I'll wait until I hear more third party people try it or I do myself.

[–] Krudler@lemmy.world 1 points 2 days ago

Of course not. They've made artificial fat, not butter. BIG difference

water, lecithin as an emulsifier, flavor and color

[–] danc4498@lemmy.world 5 points 3 days ago (1 children)

You had me in the first half

[–] bigfondue@lemmy.world 4 points 3 days ago

Bill is going to be serving this on all his jets and yachts
