Making food out of thin air might sound far-fetched, but a start-up based in Finland has developed a new technology to produce protein powder designed for human consumption out of CO2.
Solar Foods uses electricity and carbon dioxide captured from the air to create a substance, called Solein, that tastes like wheat flour - and hopes to have a product on the shelves by 2021 and feed 9 billion people by 2050.
Solein begins as a powdery substance, but like flour, it can be shaped into any number of food items. It can also be used to fortify other foods, and plant-based meat alternatives can potentially use Solein as an environmentally sustainable alternative to agricultural products.
