A team of scientists paired a plastic eating enzyme called pet enzyme with another enzyme to create a cocktail that could digest plastic six times faster than before. The team used a second enzyme found in the same bacteria that consumes plastic, which, when combined with pet, speeds up the decomposition of plastics. Pet enzyme, which can decompose polyethylene terephthalate, has been combined with a second enzyme called mhet. < / P > < p > pet is the most common thermoplastic used to make disposable beverage bottles, clothes and carpets. If left alone, it will take hundreds of years to decompose in the environment. However, when pet enzymes are used to break down bottles, the time taken for pet to decompose naturally is shortened to a few days. < / P > < p > when the enzyme was first discovered, it set off a revolution in the field of plastic recycling, creating a potential low-energy solution to reduce plastic waste. The researchers studied pet enzymes in the laboratory, making it break down plastics about 20% faster than the enzyme method in the past. When it was combined with mhet enzyme, the degradation rate of PET was doubled. < p > < p > Professor John mcgeehan co led the team behind the new enzyme and was also the scientist who designed the pet enzyme. Pet enzymes attack the surface of the plastic, while mhet enzymes break things down further, he said. The two enzymes are physically linked together, and they break down plastic about three times faster than each enzyme used alone. Both enzymes can digest the plastic and restore it to its original structure. This process allows plastics to be manufactured and reused indefinitely, reducing dependence on fossil fuels such as oil and gas. Global Tech
