This company makes food from thin air
Helsinki, Finland (CNN)In Finland, scientists are making an entirely new ingredient out of air, water and electricity — and they hope it could revolutionize the way our food is produced.
Feeding an ever-growing population is putting a huge strain on the Earth’s resources. Agriculture is one of the world’s largest sources of greenhouse gases, with animal farming in particular responsible for 14.5% of the world’s greenhouse gas emissions, mostly from beef and dairy cattle.
On top of that, farming uses vast areas of land that might otherwise be home to carbon-storing forests; it also guzzles huge amounts of water — up to 70% of water-use worldwide, according to the OECD.
But a Helsinki-based company is trying to change that.
“In order to save the planet from climate change, we need to disconnect food production from agriculture,” says Pasi Vainikka, CEO of Solar Foods.
At its pilot plant, the start-up is developing a new natural source of protein it calls Solein. Like other protein supplements, it has no discernible taste and can be added to almost any snack or meal. But Solar Foods says its product will have have a tiny carbon footprint.
Solein is made by growing a microbe in liquid in a fermentation tank. It’s similar to the process used in breweries, but instead of feeding it sugars, as you would when brewing beer, Solar Foods’ microbe eats only hydrogen bubbles, carbon dioxide, nutrients and vitamins.
Solar Foods makes hydrogen by applying electricity to water, and sources carbon dioxide by extracting it from air — which is why the company describes Solein as being “food out of thin air.” All this is powered by renewable energy, minimizing the product’s carbon footprint.
“You end up with a powder that is about 65 percent protein and carbs and fats,” Vainikka told CNN.
That powder could be added to things like bread and pasta, or to plant-based meat or dairy substitutes. One day, it could even be used as a food source for lab-grown meat, he says.
Solar Foods claims production of Solein is 100 times more climate friendly than meat and 10 times better than plant-based proteins, as well as using much less water… Read more…
