Vodka. Jet fuel. Hand sanitizer. Perfume. A growing number of companies are turning carbon dioxide captured from the air or factory smokestacks into everyday products so the greenhouse gas doesn’t escape into the atmosphere and heat the planet — or at least gets recycled a few times before it does.

Carbon capture technology works by separating carbon dioxide from other gases using expensive solvents that attract the molecules like iron filings to a magnet. Once captured, the carbon dioxide can be buried deep underground in places such as depleted oil and gas wells, where it remains for centuries. But that process has its challenges. On top of the high cost, companies also have to figure out how to transport the carbon dioxide and find the right geological structures in which to store it.
