New research from Stanford University and Beihang University would suggest that mealworms can dine regularly on styrofoam and plastic without adverse affect. They are biodegraded in the worm's gut into tiny fragments. This is potentially fantastic news considering how long it takes for plastic to normally biodegrade.
Mealworms can safely and effectively biodegrade certain types of plastic waste, according to groundbreaking new research from Stanford University and China's Beihang University. In two newly released companion studies, researchers reveal that microorganisms living in the mealworm's gut effectively break down styrofoam and plastic into "biodegraded fragments that look similar to tiny rabbit droppings."
