environmentally friendly plastic made from straw could soon be used in disposable bottles and packaging  -  polyethylene terephthalate film
After a breakthrough by British scientists, an eco-friendly plastic made of straw can soon be used in disposable bottles and other packaging.
They have found a way to "edit" the genes of microorganisms to speed up the conversion of plant materials into naturally decomposed bio-plastics.
For example, the annual crop of straw used or the beet crop, they say, will allow half of the 17 billion plastic bottles used in the country to be made from biodegradable materials.
Bio-plastics are made of wood materials, which are rigid materials that keep trees and plants standing.
The same process can be made of plastic with sugar instead of oil.
A research project at the University of Warwick and the University of York has already made the first bio-plastic with wheat straw, and experts say the technology could be mass-produced in five years.
Dr. Tim Buge, professor of biochemistry at Warwick University, said: "The breakthrough is that bioplastics can be made from wood materials, which people thought could not be done 10 to 15 years ago.
"Gene editing increases the production of wood bio-plastics and reduces the time it takes for this process so that we can make this plastic in bulk.
Wood is a good raw material because it exists in wheat straw and is a by-product of paper making, so the environmental cost is very low.
Over the past decade, the Daily Mail has led a campaign against plastic pollution.
Our ban on bag movement causes plastic bags to be charged 5 p and now the ban on bead movement causes toxic beads to be banned.
The climax of the plastic movement highlights the threat of plastic waste choking the ocean, endangering wildlife and entering the food chain after being swallowed up by fish.
The blueprint for the new bio-plastic was created at Warwick University by editing the genes of jostii red ball bacteria, a bacteria found in the soil that breaks down Wood.
By adjusting the DNA of this organism, scientists can make it over-producing an enzyme that can turn wood into a new product that can be used to make bio-plastics.
It can be rigid, flexible, or transparent film, so it can be used in many types of food packaging.
This process uses a molecular tool that allows scientists to accurately locate, cut and replace any genetic substance quickly and cheaply.
British company bioome Technologies is developing ways to use the technology and says it can also edit emails.
A catalyst for accelerating chemical reactions.
This will make the harvest faster for a long time.
Chain Molecules in sugar produce similar biodegradable plastics.

Mason, a material biologist at the University of York, said the carbon found in nature paved the way for natural substitution of polybendiester (PET)
Plastic used in water bottles now.
He also said, "50 thousand tons. Pet replacement)
The factory can produce enough plastic to replace half of all beverage bottles in the UK.
