Research project is converting carbon emissions into green construction materials
Over the next four years, Australia’s Mineral Carbonation International (MCI), which specialises in carbon utilisation technologies , will scale up a process which bonds CO2 with crushed serpentinite to create solid carbonates.
Such carbonates and silica by-products have the potential to be used in building products such as concrete and plasterboard to create green construction materials.
Serpentinite is a readily available ‘feedstock’, able to absorb CO2 and is found all over the world.
“Nowhere in the world had anyone scaled up enough to create enough material to give to manufacturers, to experiment and test them and find out what products they can make from them”, he said, underlying the correlation of scale and profitability,” MCI says.
The company has targeted a 20,000 to 50,000 tonnes of ‘green’ concrete for construction companies by 2020, anticipating that the process will be economically viable even with a low carbon price.
The initiative is expected to cost $9m.
