D The world is drowning in plastic, but only 9% of plastic products are ever recycled. Every year, over 7. 72 trillion （ kilograms of plastic are washed into the oceans. But now some bacteria may help recycle. They can”eat”other things by changing the chemicals in those things into something that will help the bacteria grow. The secret to this is enzymes（酶） that bacteria use to make chemical chanThey can work like pair of scissors, breaking apart other materials.
People are familiar with PET plastic used in water bottles. Most PET is thrown away, and even when it is recycled, It can’t be made into new bottles, which is the vital problem scientists are faced with. In rotted leaves, scientists working at the French company Carbios discovered an enzyme called LCC that slowly breaks apart PET plastic. Recently, by testing hundreds and thousands of slight changes to the enzyme, they’ve come up with new version of LCC, which can survive at higher temperatures. It can break up 90% of the PET in just 10 hours while the original enzyme takes about 20 hours and only breaks up half of the PET. The process turns the PET plastic back into the materials that it is made from. Those materials can then be used again to make new bottles or other products. Carbios hopes to start recycling plastic in large quantities by 2024 or 2025.
