PETER DOCKRILL1 OCT 2015
Garbage is a big problem. Even with so many of us doing our bit to help out with recycling, the amount of unrecyclable and discarded plastics in the US alone comes close to 30 million tonnes annually, thanks to things like disposable coffee cups (2.5 billion of which are thrown away by Americans every year). Were looking at you, Starbucks.
Now, for the first time, researchers have found detailed evidence that bacteria in an animals gut can safely biodegrade plastic and potentially help reduce the environmental impact of plastic in landfill and elsewhere. The animal in question? The humble mealworm which turns out to be not so humble after all.
Researchers led by Stanford University in US and Beihang University in China found that the mealworm the larval form of the darkling beetle can safely subsist on a diet of Styrofoam and other kinds of polystyrene, with bacteria in the worms gut biodegrading the plastic as part of its digestive process. The findings are significant because it was previously thought that these substances were non-biodegradable meaning they ended up in landfill (or worse, our oceans, where theyd accumulate for decades).
Our findings have opened a new door to solve the global plastic pollution problem, co-author Wei-Min Wu, a senior research engineer in the Department of Civil and Environmental Engineering at Stanford, said in a statement.

(70,089 posts)the next stage of the research is to make sure any animals that eat these worms are not affected by the plastics.
worms like this make excellent animal feed, better for the environment than meat.
