Extraction of Starch from Cassava Tuber as a Substitute of Polyethylene in Packaging Bag

摘要

Plastic revolutionized the industry during its invention. It helps us not only to have strong and flexible tools but also to have cheaper materials for almost everything we make. Despite of its usefulness, it also has diverse effects in our ecosystem. Hazardous chemicals leaking from landfilled plastics runs through rivers and lakes which are primary sources of water. Aquatic animal suspect plastics as foods which make them feel full all the time without nutrients coming from their body and causes them to die in hunger and the birth of "Micro plastic" pollution in the environment. Those are some of negative effects of plastics in our environment which is critical for our future generations. The researchers introduces a biodegradable packaging bag that focuses on creating a product to be used as alternative to plastics and solve the negative effects of plastics that affect environment through the use of safe and bio-degradable materials such as natural starch from cassava, glycerol, and many more. By mixing the right proportions of the main materials and perfect amount of heat, the researchers achieved the best features of the bio-degradable polymer that will be discussed later in this paper.
