Concrete is the world’s most-produced material. Its production results in nine percent of global carbon emissions. So researchers have tried to boost its ability to absorb CO2 or use less carbon-intensive alternatives to cement, concrete’s main ingredient. Almost a billion tires are scrapped around the world yearly. A new technique upcycles low-value rubber tire waste into the high-value carbon nanomaterial, graphene—keeping tires out of landfills and making concrete more sustainable and 30% stronger.
