A caterpillar that munches on plastic bags could hold the key to tackling plastic pollution, scientists say. Researchers at Cambridge University have discovered that the larvae of the moth, which eats wax in bee hives, can also degrade plastic. Experiments show the insect can break down the chemical bonds of plastic in a similar way to digesting beeswax.
Each year, about 80 million tonnes of the plastic polyethylene are produced around the world. The plastic is used to make shopping bags and food packaging, among other things, but it can take hundreds of years to decompose completely. However, caterpillars of the moth (Galleria mellonella) can make holes in a plastic bag in under an hour.

Dr Bombelli and colleague Federica Bertocchini of the Spanish National Research Council have patented the discovery. They want to speed up the process of discovering the chemical secrets behind the natural degradation of plastic. They think microbes in the caterpillar - as well as the insect itself - might play a role in breaking down plastic. If the chemical process can be identified, it could lead to a solution to managing plastic waste in the environment.

The research is published in the journal, Current Biology.

(33,643 posts)I mean, like ... is it actually 'good for them' to eat this crap, or do they just die afterwards?
Just askin' ...

(4,973 posts)do they defecate polymers? What part of the ecosystem will consume the caterpillars and will it make them sick?

If they tried breeding them a excess of larva could wipe out bee hives by eating the honey combs.
The thing that gets me is they want to patent it and haven't even isolated the bacteria yet. Also the question of patenting a naturally living organism to me shouldn't happen.

(20,219 posts)Wow, I was thinking along the line of genetically engineered bacteria, and how would we test against unforeseen consequences.
And then I come across this!
This is great news.
