Scientists claim to have found a way to produce magnesite in a lab which they claim can absorb CO2 from the atmosphere, in an announcement having major implications for climate change.
The team presented their work at the Goldschmidt conference in Boston.
Their method can use a tonne of naturally-occurring magnesite to remove around half a tonne of CO2 from the atmosphere, but the rate of formation for natural magnesite is very slow.
By using polystyrene microspheres as a catalyst, the scientists demonstrated they were able to produce magnesite within 72 days. The microspheres are unaffected by the process, so they can also be reused.
