Tires Turned into Graphene Make Stronger Concrete

Scientists have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. Concrete is the most-produced material in the world and simply making it produces as much as 9 percent of the world’s carbon dioxide emissions. If less concrete can be used in roads, buildings, and bridges, some of the emissions can be eliminated at the start.
