Everyone knows that plastics are non-biodegradable. This means that they do not decay and turn into soil even after so many years.
Not anymore! Because of modern science, there are some kinds of plastics that are biodegradable. These are called bioplastics. These plastics came from materials and ingredients that are biodegradable. Some are made from starch coming fro corn and potatoes. Others come from the proteins of soy beans. Others are made of cellulose, the chemical that makes up the leaves and stems of plants.
Many people were afraid that these plastics would be weak and easy to tear. But scientists were able to make them strong as regular plastics. Some are even stronger.
Unlike regular plastics that melt with heat, many bioplastics can stand very high temperatures. Some will not melt even at 100 degrees Celsius, the boiling point of water.
