Since the discovery of LCC, researchers like Sonnendecker have been looking for new PET-eating enzymes in nature. LCC is good, they say, but it has limitations. It is fast for what it is, but it still takes days to break down PET and the reactions have to occur at very high temperatures.
Other scientists and researchers have been trying to figure out how to engineer LCC to make it more efficient.
A French company called Carbios is doing that. They are engineering LCC to create a faster, more efficient enzyme.
Elsewhere, researchers at the University of Texas in Austin have created a PET-eating protein using a machine learning algorithm. They say their protein can degrade PET plastic in 24 hours.

The search continues, but they're finding better and better tools to degrade PET plastic!
