Urban Mining: Turning Urban Waste Into Valuable Products

Renowned synthetic chemist Jim Tour shows how we can turn discarded plastics into graphene, a product useful in industry

There’s a gold mine, so to speak, in the garbage but it takes a gifted chemist to develop processes that turn the trash to valuable industrial materials. At COSM 2021, James Tour talked about his team’s work in developing such processes: The Nanotech Revolution: Our Zero-Waste Energy Future (November 11, 2021) Dr. Jim Tour, Professor of Chemistry at Rice University, gives a riveting tour of how waste products can be converted to graphene, an extremely valuable material with a host of useful applications—from medical applications to new strong and lightweight materials to an energy source for zero CO2 emissions. Tour and his team have developed methods for turning carbon waste into graphene, an allotrope of carbon that can be stacked…

Flash Graphene: Born Again Plastic Is Planet-Friendly

Chemist James Tour outlined a new approach to carbon waste at COSM 2021: Use electricity to turn it into graphene, to be recycled as new materials

Remember that mindblowing scene in Back to the Future II where Doc Brown shows up in his flying Delorean and throws trash into the “Mr. Fusion” unit in the back — and it’s instantly converted into fuel? We aren’t quite there yet. But if what Rice University synthetic chemist James Tour told COSM 2021 proves right, then we can take current trash — e-waste, food waste, useless wood, discarded plastic, old tires, etc. — and reclaim it at low cost to make materials that we can incorporate into many technologies. Tour and his team have developed methods for turning carbon waste into graphene, an allotrope of carbon that can be stacked to form graphite (best known as the “lead” in…
