Welcome to cultured meat – not pigs reading Proust but a viable alternative to slaughter

Where do you think livestock feed comes from?

Grass, sileage, feed pellets. But same kinds of places feedstock for vat grown meat would come from. Or perhaps not and that feedstock would come from refineries given it'd need to be in a form cells could process rather than be processed by an animal's digestion.

But it's also one of those fun land use things the anti-meat brigade may overlook. So one example-

https://www.feedipedia.org/node/23075

Abraded peel: the peel removed from raw potatoes intended for crisp processing.

Potato slurry / potato puree / potato filter cake: material from water recovery systems (oxidation ditch, belt solids, filter cake) containing variable amounts of microbial cells, solubles and of potato particles after filtration (filter cake or gray starch: sludge from settling tanks, comprised of free starch and small potato pieces).

Screen solids: small potatoes and slices, white waste, nubbins, hopper box.

Potato pulp from starch extraction.

Potato protein concentrate

And then there's stuff like carrot tops, or whole carrots that don't make the grade to end up in supermarkets. We could be eating more of that, but generally don't. And if we don't eat those byproducts/waste, then we'd have to do something with them. Currently there's some competition to turn those products into methane (aka biogas) and CO2 artificially rather than letting it rot naturally and releasing those greenhous gases.

And then waste from animals (ie slurry etc) gets used as fertilser for food & feed crops and if there was less meat production, alternatives would be needed or soil degrades and vegetable yields and quality falls. Or food prices increase because more synthetic products are needed instead of current use of 'waste'.
