Scientists makе biodegradable plastic Plastic has been a blight on the landscape and a deadly threat to wildlife for decades. Environmentalists have issued many pleas for us to reduce the amount of plastic we use or switch to biodegradable alternatives. One solution to this problem may be at hand. Scientists have develoрed a form of biodegradable plastic. This means that the billions of plastic bags, cups, straws and utensils that we dispose of each day could be "compostable" - they could decompose and break down as naturally as organic waste. The scientists are from the University of California, Berkeley. They say they have invented a plastic that could break down within a few weeks, rather than centuries, using just heat and water. The new, biodegradable product involves embedding polyester-eating enzymes into theе plastic during the production process. When these enzymes are exposed to heat and water, they eat away at thе plastic and reduce it to lactic acid. This provides nutrients for the soil when composted. Professor Ting Xu said up to 98 per cent of the plastic her team made degraded into small molecules. She said: "We are basically saying that we are on the right track. We can solve this continuing problem of single-use plastics." She added: "Look at all the wasted stuff we throw away-clothing. shоes, electronics like cellphones and computers. We are taking things from the earth at a faster rate than we can return them." 1. The article says plastic is very bright in the landscapре. 2. The article says scientists have several solutions for plastic. 3. The scientists said the plastic they created could be compostable. 4. The new biodegradable plastic could take weeks to decompose. 5. The new plastic contains enzyme-eating polyester.​
