‘Transforming … pollutants into valuable, reusable chemicals’

Experts from a collection of universities have their laser beams aimed at the world’s massive plastic pollution problem. And the result of their experiments could one day be realized each time we hit “save” on our devices.

The University of Texas-led research uses lasers and two-dimensional materials to reduce hard-to-breakdown plastics to base components that can be reused. Fascinatingly, the recycled elements are eyed as potential information-storing parts in next-gen computers,

“By harnessing these unique reactions, we can explore new pathways for transforming environmental pollutants into valuable, reusable chemicals, contributing to the development of a more sustainable and circular economy,” Texas Professor Yuebing Zheng, a leader on the project,

in the summary.

Experts from the University of California, Berkeley, Tohoku University in Japan, Lawrence Berkeley National Laboratory, Baylor, and Penn State contributed laser-focused insight to the innovation.

to the experts.

Low-power light is used to break chemical bonds in the plastics. New bonds are made that fascinatingly turn the waste into “luminescent carbon dots.” The 2D dichalcogenides catalyzed the reaction, helping to make possible the chemistry that forms the dots. The carbon-based nanomaterials are the parts that could work in future computers,

“It’s exciting to potentially take plastic that on its own may never break down and turn it into something useful for many different industries,” Jingang Li, a postdoctoral student at UC Berkeley who started the research at UT,

In the future, the chemical-bond altering laser treatment being developed at UT could help reduce the problem on a large scale if the process can be successfully rolled out. The experts are studying the technique with that goal in mind, they
