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.

If it's not dairy, is this not margarine rather than butter?

Also, a

proprietary process

Ugh, capitalism

[–] john_lemmy@slrpnk.net 99 points 2 weeks ago (3 children)

I mean, it was backed by Bill Gates, mr proprietary himself

[–] Tollana1234567@lemmy.today 10 points 2 weeks ago

Gates

just like he did the vaccines/.(not for himself but for the pharma companies.)

The basic process is not proprietary. It's just the Fischer-Tropsch process. It's been in use since WWII. It produces hydrocarbon chains of arbitrary length from whatever hydrocarbon feedstock you can provide.

Dietary fats are just certain short-chained hydrocarbons accompanied by certain flavorful compounds.

The "proprietary" part is what chemicals they add to the synthesized fat to make it sufficiently comparable to butter.

The Nazis used the same basic process to produce "butter" from coal feedstocks about 90 years ago. This is nothing new.

[–] Swedneck@discuss.tchncs.de 1 points 5 days ago

but also we already have margarine that tastes close enough to butter, so this thing is at best "hey guys we made margerine taste slightly more like butter"

the brand i've used which is very butter-like just adds some sort of field bean extract and some orange food colouring lmao

It is neither plant or animal based, the chemical composition is claimed to be like butter, so it is even less margarine than it is butter. Margarine is hardened plant oil or technically it can also be made from animal fat. So this is neither margarine or butter, it is synthetic butter, since it synthesized chemically, rather than made by the traditional more natural method.

But yes capitalism indeed. Why try to help the world if you can't make money on it? 🙄

This isn't new technology. This is the Fischer-Tropsch process, which cracks and/or lengthens hydrocarbon chains to produce molecules of the specifically desired length. The Germans used this same process almost a century ago. They cracked coal to produce lighter chemicals (primarily methane) then re-lengthened those methane chains to produce a variety of products, ranging from fuels, lubricants, and yes: edible "butter".

This article repackages the same technology the Nazis used to feed their U-boat crews in WWII.

[–] drmoose@lemmy.world 30 points 2 weeks ago (1 children)

You frame it like it's a bad thing but even if the process is mostly the same isn't that good? Also we can clearly improve on a 100 year old technology even if it's "solved".

[–] Rivalarrival@lemmy.today 80 points 2 weeks ago (3 children)

My primary issue is that the entire article is somewhat deceitful. They use phrases like "never seen before", "unprecedented", "pioneering", but those characteristics do not really apply to the +90-year-old technology. The only significant part of the "process" that is different from what was uses in WWII is the specific flavor packs they add to the product.

Their deceitful comments about the technology have me questioning the veracity of the rest of their claims.

Don't get me wrong: I think that Fischer-Tropsch is one of a few important technologies we need to be adopting. The reason we need to adopt it is because it is incredibly energy intensive, but not necessarily time critical. It can provide a profitable sink for excess solar energy production during long summer days, to produce hydrocarbon fuels for the transportation and aviation industries, yet switch offline overnight, overwinter, and during inclement weather, when solar can't meet demand.

But we just don't consume enough butter for this application to be useful to solar generation.

The Air Force experimented with Fischer-Tropsch "SynFuels" about 15 years ago. They actually certified most/all military aircraft to burn SynFuels, to lessen our military's reliance on foreign oil.

Once we kill the Earth, this will be how food is manufactured. I am now going to finish my box of Soylent Green.

I'm not sure why people are so puritanical about this. I think Beyond Burgers and Soylent are great.

I'm not sure if that's a bad thing. Current food sector is rotten to the core. For most, food is entertainment that is incredibly inefficient at what it does and causes incredible ethical harms that we choose to conciously ignore.

...carbon dioxide, hydrogen, and oxygen...

Pretty sure that is what regular butter is made out of too.

[–] mfed1122@discuss.tchncs.de 36 points 1 week ago

Yes, they aren't trying to make an alternative butter substitute as I understand it. They're trying to make real butter via a purely chemically synthetic process.

[–] RBWells@lemmy.world 37 points 2 weeks ago (3 children)

How is this not just crisco, hydrogenated fat? Butter seems like it has more going on, traces of milk proteins & sugars that give it flavor.

[–] exasperation@lemmy.dbzer0.com 15 points 1 week ago

Hydrogenated vegetable oils still start with vegetable oil, which have to be extracted from farmed crops (mostly soybeans).

This is a process that skips living feedstock from biological organisms and assembled the fatty acids directly from methane, water, and carbon dioxide. No photosynthesis, no cellular metabolism, nothing like that.

This isn’t butter, this is one type of butter fat. It’s missing the milk solids, proteins, and other molecules that contribute to butter’s smell and taste.

[–] waterSticksToMyBalls@lemmy.world 14 points 1 week ago (1 children)

I bet that price is the main issue. The reason all of these startups fall into oblivion is that price is astronomical.

[–] Swedneck@discuss.tchncs.de 1 points 5 days ago* (last edited 5 days ago)

but also in this case we already have perfectly fucking fine margerine, if you splurge on slightly more expensive (which is still like half the fucking price of butter) stuff it'll taste pretty damn close to butter so long as you're not doing a side by side comparison.

[–] Saleh@feddit.org 23 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

I would like to see the LCA analysis on this one. I would not be surprised if this ends up using energy causing more damage than the damage that dairy farming methane and land conversion is doing.

[–] surewhynotlem@lemmy.world 23 points 2 weeks ago (7 children)

I'd be very impressed if this somehow created more methane than cow farts.

Sound like coal butter, which existed in WW2 but was discontinued because of inefficiency.

And the most important question: how does it taste?

No the most important question is how much energy does it take?

[...] they take carbon dioxide from the air and hydrogen from water, [...]

So direct air capture, instead of industrial waste CO2, good luck with that.

If Bill Gates is involved we can be sure it's to help humanity, and not to help capitalists and rich people to get richer.

He has a very good PR team because this man was also backing the former Monsanto company, with proprietary grains, supposed to help solve famine in the world, but causing poor farmers to be sued into bankruptcy and commit suicide. Oh and the grains also commit 'suicide' so if you are not sued because the wind flew proprietary grains to your field, you better have enough money to buy new grains from corporations every year.

So I'm sure anything he does can't be bad. It's all altruistic and for the good of humanity. Surely nothing proprietary there. All open source. For humanity.

Fuck Bill Gates.

“Tastes just like the real thing” is a sure sign that it is almost, but not quite, entirely unlike the real thing

[–] filcuk@lemmy.zip 10 points 1 week ago

Typically there are minor 'impurities' that make the 'real' thing taste different.
Vanillin, for example, is very easy to produce chemically, which is good, because growing and harvesting it naturally is very difficult, but it's missing a lot of the compounds which add subtle yet important taste and smell to the natural stuff.

Sure, if you want to call a hydrocarbon like methane "carbon" I guess. Why not.

Anything but stop polluting...

We could cut our carbon emissions? NO, no! This is an opportunity for profits! We can use this to squeeze just that bit more money out of people and it sets us up nicely to replace real butter when the total collapse of the ecosystem means that real dairy becomes an impossible luxury.

So, how's that work on bread made from sand coming along?

Whilst yes, uplifting, I also have a certain inherent skepticism to artificial facsimiles. Too often it's an unwelcome discovery.

For instance about a year ago we found a new product in the cheese aisle, slightly cheaper than regular gouda and called "gaudina" - turns out, not actually cheese but instead made from milk powder, palm oil and other assorted stuff.

Until somebody proves through proper trials and reviews that the products have no statistically significant difference in health outcomes, I'll be hesitant.
