CO2 Removal,
powered by nature
THE OPPORTUNITY
A natural carbon sink
Mineral carbonation, the reaction of CO₂ with metal oxides to create carbonates, occurs naturally around the world.
Limestone, or calcium carbonate, is ~15% of the Earth's sedimentary crust, making it a critical global carbon sink.
By harnessing the natural ability of limestone, we can permanently remove CO₂ at the gigatonne level.
THE CATCH
We need zero carbon lime
If we are to enhance this natural process to remove atmospheric CO₂, we need to produce zero carbon calcium oxide, commonly known as lime. And lots of it. This can act as a “carbon sponge”, absorbing atmospheric CO₂ by forming calcium carbonate.
However, current methods for producing 1 tonne of lime emit approximately 1 tonne of CO₂, negating any environmental benefit from mineral carbonation.
OUR SOLUTION
Greener, circular & decentralised lime production, letting lime act as a carbon sink
Renewably powered kilns
Our advanced kilns can run on renewable energy sources, with a proprietary process allowing the easy capture of CO₂ for permanent sequestration by partner organisations.
Using low value feedstocks
Our process is able to utilise feedstocks with limited other use cases; lowering costs and enhancing circularity.
Allowing nature to work its magic
Our lime will be used to maximise mineral carbonation. This means for every 10 tonnes of lime produced, we can remove up to 7.86 tonnes of CO₂ from the atmosphere (on a gross basis).
