NarvasaJohn Lloyd S. JalangChariz R. MoldezMarch 2017Chapter 1RATIONALEHumans utilize plastic in everyday life. It is very easy to spot materials that are made out of plastic or contains plastic. It is an undeniable fact that people should be aware of since the ever-growing demand of plastic results to even more plastic wastes which harms the environment. Plastics are really helpful but the immense usage and productions, along with the improper disposal of used plastics takes a toll on the environment’s wellbeing.

According to the History of Plastics (2017), there are three major negative effects of plastics and first of it is environmental harm. The ever increasing plastic production since 1950s managed to saturate the world with waste plastic products that can cause major effects on the environment. Decomposition of plastic products can last from 400 to 1000 years with newer “degradable” compounds, but before that degradation can take place waste plastic will continue to clog our waterways, oceans, forests, and other natural habitats that are filled with animals who mistake dangerous plastics for food.

It is known worldwide that the creation and recycling of plastics can cause serious environmental risk, but some of the additives that are infused in plastic can cause permanent harm to our metabolism otherwise a chemical risk.And lastly, plastics are choking hazards. Plastic is one of the most popular building materials for small items around the world. This is most evident in the toy industry, where vast majority of children toys is manufactured with plastic.

These toys and small plastic objects of many uses can easily get into children’s hands (especially babies and toddlers) that unknowingly put them in their mouth. Developing countries, such as the Philippines, run on a “sachet economy”, which encourages the practice of buying Fast Moving Consumer Goods (FMCGs) in small quantities making Philippines the third biggest source of plastic ocean pollution because of the cheap, disposable plastics produced. (Abigail Aguilar, 2017)Speculators in Maco agree that the dilemma is getting worse as they observed public areas getting loaded with various plastic wastes. This growing predicament caught the eye of the researchers and decided to make plastic that easily decomposes.

Bio-plastics are a great alternative to traditional plastics, which are often composed of petroleum products.RESEARCH QUESTIONSWhat makes coconut oil an effective non-toxic plasticizer?How long will the bio-plastic decompose in natural conditions?Is this bio-plastic safe for the substitution of plastics for food packaging, children’s items/toys, etc.?HYPOTHESISIf the coconut oil is used as a substitute non-toxic plasticizer, then bio-plastic is produced.SCOPE AND LIMITATIONSThis study aims to produce a bio-plastic that will replace the general use of non-biodegradable plastics, therefore mitigating the environmental impact brought by plastic wastes. The Philippines that is running on a “sachet economy” will make great use of this study by using bio-plastic in the packaging of the sachet products (which will eventually get discarded afterwards) generally, the whole industry can lessen plastic wastes and its harmful environmental risks by introducing bio-plastic as a standard usage to the economy. This study was conducted from January 2017 to March 2017.We acknowledge the weaknesses and limitations of this study to determine in which aspects can future researchers can contribute to our efforts in lessening this environmental dilemma.  The cons of bio plastic according to Greenhome., when bio-plastics can someday be conventionally utilized in the industry, most people will rely on the fact that bio-plastics can indeed decompose and may encourage them to litter more, and the biodegrading of bio-plastics may require a specific set of conditions which may not be available at all times. (i.e. in landfills), also, reproducing bio-plastics using coconut oil as plasticizer may be a challenge in other countries since coconuts are only available rampantly in tropics considering this study is based on the Republic of the Philippines.

SIGNIFICANCE OF THE STUDYThis study is significant because it aims to produce a biodegradable plastic to substitute non-biodegradable plastics in its conventional, everyday use, thus, lessening the environmental impact of too much discarded plastics that clogs the waterways, pollutes the habitat of animals and some may release harmful chemicals used in the manufacturing of these plastics to the living organisms of a certain environment.DEFINITION OF TERMSCoconut Oil: Also known as copra oil, is an edible oil extracted from the kernel or meat of mature coconuts harvested from the coconut palm. In this study, coconut oil is used as the plasticizer for the bio-plastic.Bio-plastic: Bio plastics are plastics derived from renewable biomass sources, such as vegetable fats and oils, corn starch, or micro biota. (Wikipedia) This is the dependent variable of our study.

Plasticizer: Plasticizers or dispersants are additives that increase the plasticity or decrease the viscosity of a material. These are the substances which are added in order to alter their physical properties. (Wikipedia) This is the role of the coconut oil in this study.Biodegradable: Able to decompose naturally: made of substances that will decay relatively quickly as a result of the action of bacteria and break down into elements such as carbon that are recycled naturally (Microsoft Encarta 2009), this is how we hope our finished product would be like.Chapter 2Locale of the study The production of bioplastic was made at the proponent’s 1377 San Gabriel District, Poblacion Maco, Compostela Valley Province.Materials:      1.

1 tbsp cornstarch 5. Spatula      2. 1 tsp vinegar 6. Small Pot      3. 1.

tsp coconut oil 7. Aluminum Foil      4. 4 tbsp water 8. Measuring Cups      Procedures: Gather the materials needed, which will be collected at the supermarket at Tagum City.Add the water, cornstarch, vinegar and the coconut oil into the small pot.

Heat the materials and stir regularly to avoid clumping.Turn off the heat then let the mixture cool.Scoop the cooled mixture then form into plastic.Let it hardened overnight until completely set.After the steps taken, the bio-plastic is ready for experimentation  Testing’s:Tensile Strength TestThe bio-plastic and a commercial plastic will be experimented with various weights to determine its tensile strength. (Green Plastics, 2013)Flexibility TestThe bio-plastic, along with the commercial plastic, will both be stretched to see its flexibility. (Green Plastics, 2013)
