Superworm eats styrofoam

Australia has a larva that eats styrofoam.
A plump larva the length of a paper clip can survive on the material that makes Styrofoam. The organism, commonly called a “superworm,” could transform the way waste managers dispose of one of the most common components in landfills, researchers said, potentially slowing a mounting garbage crisis that is exacerbating climate change.

In a paper released last week in the journal of Microbial Genomics, scientists from the University of Queensland in Brisbane, Australia, showed that the larvae of a darkling beetle, called zophobas morio, can survive solely on polystyrene, commonly called Styrofoam.

Now, the researchers will study the enzymes that allow the superworm to digest Styrofoam, as they look to find a way to transform the finding into a commercial product. Industrial adoption offers a tantalizing scenario for waste managers: A natural way to dispose and recycle the Styrofoam trash that accounts for as much as 30 percent of landfill space worldwide.

In 2015, researchers from Stanford University revealed that mealworms could also survive on Styrofoam. The next year, Japanese scientists found bacteria that could eat plastic bottles. In April, researchers from the University of Texas found an enzyme which could digest polyethylene terephthalate, a plastic resin found in clothes, liquid and food containers.

[Ed. Note: I know from personal experience that styrofoam can be easily dissolve with a petroleum solvent like, say, gasoline. I guess the trick is really to get all the styrofoam separated from all the other stuff.]
