A superworm can eat about eight times more than other plastic-ingesting insects.
Recycling seems like a simple cure for our plastic addiction: just take the plastic we have and make it into new items. But problems abound. Current technology mostly creates plastic of a lower quality than it was before, many types of plastic aren’t recyclable at all, and much of the plastic is floating in the ocean, not even in the recycling stream. So it’s vital that we find new ways to break down plastic, and scientists have just discovered one: a superworm that can eat about eight times more than other plastic-ingesting insects like mealworms.
Superworms are actually beetle larvae, and commonly sold at pet stores as food for reptiles and fish. In a paper recently published by the American Chemical Society, researchers Jiaojie Li, Dae-Hwan Kim, and their team detail how they placed 50 superworms in a chamber with two grams of polystyrene. After 21 days, the superworms had consumed about 70% of the polystyrene.
