Rice, C-Crete team optimizes conversion of tire waste into graphene for stronger concrete

Green Car Congress

Rice University scientists and their colleagues at C-Crete Technologies have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. After useful oils are extracted from waste tires, this carbon residue has until now had near-zero value, Tour said. 2021.03.020.

U Delaware team develops chemocatalytic process to convert waste polypropylene to lube oils

Green Car Congress

Researchers at the University of Delaware have shown that ruthenium deposited on titania is an active and selective catalyst for breaking down polypropylene into valuable lubricant-range hydrocarbons with narrow molecular weight distribution and low methane formation at low temperatures of 250 °C with a modest H 2 pressure. 1c00874.
