California startup Savor has developed butter made without milk — from carbon dioxide and water. The technology captures CO₂ from the air and hydrogen from water, then synthesizes fats — triglycerides identical to natural ones. The result is a product indistinguishable in taste and culinary properties from classic butter.
The main advantage is its minimal carbon footprint. Producing one kilogram of “butter from air” creates less than one gram of CO₂, whereas conventional butter generates between 5 and 15 kilograms. The butter is already being tested in California bakeries, where it has received positive reviews from both chefs and customers.
Unlike natural butter, the artificial version contains no vitamins, proteins, or minerals: it consists almost entirely of fat. However, the product also contains no cholesterol, milk proteins, or lactose, so it may be suitable for people with milk-protein allergies, lactose intolerance, lactase deficiency, and cholesterol concerns.
The project has been supported by Bill Gates, and the Savor team is working on creating other dairy analogues. It is also studying the possibility of adding important nutrients later to make its profile closer to conventional butter. The startup aims to scale production and enter the mass market after passing all safety checks.
Would you be ready to overcome the psychological barrier to “artificial” and “lab-grown” products?
