Before I acknowledge the people who supported this Science Investigatory Project, I dedicate this project for the people who believe on the quote which is “Less is more”. I shall formally dictate all the people who supported this Science Investigatory Project, first and foremost, God who have given us the time ,the strength or determination to finish this project and thanking him for his holy support, secondly our parents for the financial and moral support that made much for our project and most of all their patience towards us, on the way, we whole heartedly thank the most reliable sources though some other sources were made by anonymous persons, still we blindly give thanks to them, Wikipedia for the additional sources, (magdagdag kayo ng ibang researchers dito, before the coma), I shall acknowledge the persons who paved way on giving this project, a very innovative on constructing special structures such as vases and many more. Lastly our members who gave their full attention to this project, their full determination to fulfill this long endured and awaited project. Let this project be the success of the innovative bio plastics.
Background of the Study
Plastics are used because they are very useful, cheap, manageable and handy. Plastics have been the fastest growing basic material because they are versatile, light weight, energy saving, durable and recyclable. It has become a popular material used in a wide variety of ways. Plastics can last a long time but unfortunately, this same useful quality can make plastic a huge pollution problem. Its long life means it survives in the environment for long periods where it can do great harm. Non-biodegradable plastics are durable but they degrade very slowly; molecular bonds that make plastic so durable make it equally resistant to natural process of degradation. Plastic packaging provides excellent protection for the product, it is cheap to manufacture and seems to last forever. Lasting forever, however, is proving to be a major environmental problem. Plastics are also a huge problem in waste disposal and studies have been made to find a substitute material which can be used in making biodegradable plastics. Because plastic does not decompose, and requires high energy ultra-violet light to break down, the amount of plastic waste in our oceans is steadily increasing. Studies that have been done locally show about 3, 500 particles of plastic per square kilometer of sea off the southern African coast. The world production of plastic is estimated to be more than 100 million tons per year. Plastics are indeed a threat to wild life. A great proof for this is that plastics have been found in the stomachs of sea turtles, birds, and fish all over the world. Tragically, millions of tons of plastic are poisoning our oceans. Plastic pollution harms people, animals, and the environment because it is non-biodegradable. In the marine environment, plastic breaks down into smaller and smaller particles that absorb toxic chemicals, are ingested by wildlife, and enter the food chain that we depend on. People need alternative and effective components of plastic that is safe and biodegradable which will not harm and pollute the earth.
Significance of the Study
This study is important to be able to help Mother Earth in reducing its pollutants and toxic or harmful wastes. Through this study, the researchers will be able to help other people, the...
