A group of scientists from IBM and Stanford University announced Wednesday a chemistry breakthrough that could change the nature of plastics and plastics recycling.
Using organic catalysts, the team has developed a new method for producing and breaking down plastic polymers.
"Additionally, the team has developed a new strategy for the synthesis of high molecular weight cyclic polyesters and the generation of new families of biocompatible polymers for biomedical applications," according to IBM.
In terms of real-world application, the science could lead to plastics becoming endlessly recyclable rather than junk in a landfill.
As IBM points out, many plastic bottles, while they are now being recycled, can only be recycled once for what is called "second-generation use." Most bottles made from second-generation recycled plastic cannot be recycled yet again, and so are typically sent to landfills.
Many people have been working on the plastics issue, and there are several organic-based recyclable plastics being introduced. In February, for example, plant- and cornstarch-based plastic products including household paper goods, food packaging, and
Details of the polymer development can be found in the paper "Organocatalysis: Opportunities and Challenges for Polymer Synthesis," which has been published in the American Chemical Society journal, Macromolecules.
