Summary

Researchers developed a chemo-microbial strategy to degrade polyethylene terephthalate (PET) by using mechanochemistry to control the polymorph of the intermediate BHET, demonstrating that crystal form directly influences how quickly bacteria can break down the degradation product.

Polymers

Here, we optimized a chemo-microbial degradation of polyethylene terephthalate. Developed a path to mechanochemically interconvert between BHET polymorphs and established that BHET polymorphism influences bacterial biodegradation rate.
