It was the first patent to make bottles by plastic compounds in 1940. For the purpose of making the bottle, the special compound was chosen for one reason that the compound can survive millions of years in the environment. It has also been found in the study that polyethylene terephthalate, a specialized plastic compound, has become the main cause of pollution in most parts of the earth surface and water.
The scientists of the National Renewable Energy Laboratory (NREL), under the Portsmouth University and the US Energy Ministry, find out the enzyme during researching with another topic. Researchers have found that the enzymes help a special bacteria to break the plastic compound 'PET' or 'digest it' by eating.
Professor John Mc Guhan of Portsmouth University said that after learning about this power of enzymes, they started trying to increase that power. They use some amino acids on the enzymes and found that enzymes consuming plastic faster. Scientists say that the enzyme is not toxic at all, this method can be very effective in the future to reduce the amount of plastic waste. However, more research is needed. Reuters.
