Background of the study
Filipinos are fond of eating bin fast-food counters where Styrofoam, plastic cups, they become disposable, thus becoming the bulk of our garbage. They are also considered as non-biodegradable, hence, cannot be used again by other living things. The only way is to convert them to another usable form.
Moreover, due to large production of plastics, they bring pollution and deterioration in the environment. Destruction of the present surroundings results when disposing plastic continuously are not controlled.
Plastic is a synthetic material that is made by polymerizing molecules of monomer materials that are derived from coal, petroleum, or natural gas. It is a preferred material because it is lightweight, flexible, durable, versatile, and mostly affordable. It is used for manufacturing a wide range of products, including packaging for food and beverages, dishes, cooking utensils, containers, eyeglasses, computers, phones, toys, furniture, and many others. History of Plastic
The first known manmade plastic was introduced in 1862 at the Great International Exhibition in London by a man named Alexander Parkes. Called Parkesine at that time, it was an organic material from cellulose that could be molded after it was heated, and it could retain its shape when it was cooled. During the late 19th century, an American by the name of John Wesley Hyatt used celluloid to produce billiard balls, and this celluloid became known as the first thermoplastic. Further improvements were made to plastics at the turn of the 20th century. Another form of plastic called cellophane was...
