A group of Finnish scientists has gained A eu innovation award for making carbon-adverse precast concrete.
Their system makes use of CO2 gasoline which mineralises as carbonate By way of the curing course of, eliminating The want for power-intensive Portland cement as a binder.
Developed by Finland’s nationwide evaluation institute VTT, the so-referred to as Carbonaide system gained first prize Inside the “anticipated influence” class of The eu Research and Know-how Organisations’ Innovation Awards on 12 October.
Swedish contractor Skanska used Carbonaide yard-paving blocks at Definitely one of its enchancment websites this autumn.
VTT is now commercialising Carbonaide To purpose to get a share of the $370bn-a-yr worldwide concrete merchandise and parts market.

It Desires to have 100 manufacturing models put in Throughout the globe by The prime of this decade and to be binding 500 megatons of CO2 a yr by 2050. It purposes to get CO2 from current emissions buying and promoting platforms.
“The tactic is suitable with The current manufacturing course ofes of concrete,” said Tapio Vehmas, VTT senior scientist and chief of the Carbonaide group.
“It Might be used for manufacturing all precast concrete parts and merchandise,” he added.
VTT said that when industrial wastes like metallic slag and bio-ash are used Inside The tactic Rather than regular cement, the concrete’s carbon footprint plunges to -60kg per cubic metre of concrete. The carbon footprint of typical concrete is roughly 250–300kg per cubic metre.
