Tires turned into graphene that makes stronger concrete

Scientists at Rice University have optimized a process to convert waste from rubber tires into graphene, which can be used to strengthen concrete. The process was introduced in 2020 by the same scientists and has been used to convert food waste and plastic into graphene by exposing them to a jolt of electricity, which removes everything but carbon atoms from the sample. Those atoms then reassemble into graphene. This time, the scientists applied the process to tire-derived carbon black and found that about 70% of the material converted to graphene.
