Optimized flash process could reduce carbon emissions. Rice University scientists have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete.
The environmental benefits of adding graphene to concrete are clear, chemist James Tour said.
“Concrete is the most-produced material in the world, and simply making it produces as much as 9% of the world’s carbon dioxide emissions,” Tour said. “If we can use less concrete in our roads, buildings and bridges, we can eliminate some of the emissions at the very start.”
Recycled tire waste is already used as a component of Portland cement, ...
