Description

The CEO of Sublime Systems chats about their alternative to make cement. Generating about 8% of all global carbon dioxide emissions, Leah is using an exciting electrochemical process to reduce this figure. It’s used in the buildings around you, the roof over your head and the foundations beneath your feet - so how difficult will it be to reduce these high carbon emissions?
