From supermarket bags to CDs, man-made waste has become a very serious problem. Recently, scientists may have found an unusual way to solve the problem. They say the waxworm (蜡虫), who eats beeswax as food, also appears to eat polyethylene, one of the strongest kinds of plastic.

Scientists have described the tiny worm’s ability as “very exciting”. Federica is a beekeeper. She put the waxworms into a plastic shopping bag which became full of holes a few minutes later. Then Federica did many more experiments. When 100 waxworms were put into a normal plastic bag, the holes began to appear in just 10 minutes.

According to the scientists, a kind of enzyme (酶) produced by the waxworm is the key. They also say that the waxworm turns the plastic into a different thing. It is used in making a material for cars. It is not clear if (是否) the waxworm can produce a large number of such things. Plastic is not a kind of natural food for the waxworm. “Wax is a kind of natural plastic. It is similar to polyethylene,” Federica said.

Scientists say they still need to know how wax is digested (被消化) in the waxworm. Federica said they would use the result to find a way to make the plastic waste disappear. “But we should not throw plastic bags into the environment, just because we now know how to break them down,” she added.
