Graphene added at less than 1% by weight nets strength improvements of greater than 20%, the partners say.

The UK specialty chemical maker Thomas Swan will supply its graphene nanoplatelets to Concrene, a University of Exeter spin-off that wants to lower the carbon footprint of concrete production. The start-up says strengthening concrete with graphene allows builders to use less of it, thus reducing carbon emissions. According to the partners, concrete production is responsible for 8% of the world’s carbon emissions.
