Butter made from CO2, not cows, tastes like ‘the real thing’, claims startup

Savor, backed by Microsoft billionaire Bill Gates, says product has lower carbon footprint as it doesn't need cows

Butter made from air instead of cows? A California-based startup claims to have worked out a complex process that eliminates the need for the animals while making its dairy-free alternative taste just as good.

Savor, backed by the Microsoft billionaire Bill Gates, has been experimenting with creating dairy-free alternatives to ice-cream, cheese, and milk by utilising a thermochemical process that allows it to build fat molecules, creating chains of carbon dioxide, hydrogen and oxygen. The company has now announced a new animal-free butter alternative.
