INTRODUCTION
Background of the Study Plastic is the most convenient material man ever discovered due to its relatively cheapness, ease of manufacture, versatility, and imperviousness to water. Plastics are used from paper clips to spaceships, and displaced materials such as wood, metal, bones and horns, stone, leather, paper, even ceramics in most of their former uses. But plastic seemed to create a drastic effect. Because it is composed of chemicals (petroleum-based), takes too long to degrade (considerably non-biodegradable), improper disposal has lead to waste problems and pollution, destructing our environment. A solution was achieved— the bioplastic. Bioplastic is just like plastics, but instead of non-renewable petroleum as source, it uses organic sources like plant sources (corn starch, soybean oil, hemp oil, etc.) and microbial sources. They can be made by using plant sugar conversion, fermentation and cultivation. Unlike petroplastics they are biodegradable when disposed properly, reducing waste production. Scales are simply fish’s protection and substantially useless for people. A waste indeed, but if this can be a source of bioplastics, there will be a help for waste reduction at the same time with fossil fuel consumption, environment conservation and a cheaper alternative from the usual plastic.

Statement of the Problem The study aims to produce bioplastic products from scales of Blue Tilapia (Oreochromis aureus) and Nile Tilapia (Oreochromis nilocitus nilocitus) indifferent or better than the first bioplastic products using fermentation process. This study is concerned in finding answers to following questions: 1. Is fermentation a possible way to produce bioplastic from the scales of the 2 tilapia varieties? 2. How much plastic can be obtained from a unit of mass (kg) of fish scales? 3. Is there a significant difference between an ordinary bioplastic product and the produced plastic in terms of : a. Physical Properties b. Biodegradability c. Durability
Significance of the Study Plastic changed our lives for many years, yet not our environment. Even plastic is the best material for almost everything, it has also its negative side. Plastic contributed much on waste production. It worsened pollution, and is also consuming petroleum which reached its critical level these days.
3 Conducting this study can therefore promote and help the alternative for plastic— the bioplastic. If tilapia scales can be a source of bioplastic, then it will be an aid for cutting off fossil fuel usage. Pollution may decline as waste reduction progresses since these polymers are from waste and will decompose.
Scope and Delimitations The study will be operated to determine the possibility to produce bioplastic from two (2) different varieties of tilapia– the Oreochromis aureus (Blue Tilapia) and Oreochromis nilocitus nilocitus (Nile Tilapia). This study includes microbial fermentation as a process to produce plastic from melted scales of tilapia varieties. This study limits itself to the determination of the possibility fish scales as source of bioplastic and does not intend to seek for its effect and further processing for a specific usage.
Definition of Terms a. Bioplastic -Bioplastics are plastic resins developed from renewable agricultural feedstocks or organic sources, such as corn sugar, hemp oil and soy bean oil. b. Tilapia -common name for nearly a hundred species of cichlid fishes from the tilapiine cichlid tribe. c. Scales -small flat bony or horny overlapping plates that cover the bodies of fish.
4 d. Fermentation -breakdown of carbohydrates by the use of microorganisms.
5 REVIEW OF RELATED LITERATURE
Tilapia Tilapia has become the third most important fish in aquaculture after carps and salmonids, with production reaching 1,505,804 metric tons in 2002. Because of their large size, rapid growth, and palatability, a number of tilapiine cichlids are at the focus of major aquaculture efforts, specifically various species of Oreochromis, Sarotherodon, and Tilapia, collectively known colloquially as tilapias. Like other large fish, they are a good source of protein and a popular target for artisanal and commercial fisheries. Originally, the majority of such fisheries were in Africa, but accidental and deliberate introductions of tilapia into freshwater lakes in Asia have led to outdoor aquaculturing projects in countries with a tropical climate such as Papua New Guinea, the Philippines, and Indonesia. In temperate zone localities, tilapiine farming operations require energy to warm the water to the tropical temperatures these fish require. One method involves warming the water using waste heat from factories and power stations. Cycloid scales are found in the majority of bony fishes like tilapia. The anterior part of each scale is usually overlapped by the posterior portion of the scale in front. This arrangement of imbricate scales gives the fish greater flexibility than those in species with cosmoid and ganoid scales. Cycloid scales consist of two main regions, a surface “bony” layer composed of an organic framework impregnated largely with calcium based salts, and a deeper fibrous layer composed mainly of collagen, a member of biopolymer family, under proteins.

Bioplastics Bioplastics are special types of biomaterials. Plastics derived from plant sourcessoybean oil, hemp oil, corn starch etc.-or microbial sources, rather than traditional petrochemical-derived plastics are called bioplastics. Microbial bioplastics are polyesters that are produced by a range of microorganisms cultivated under various growth and nutrient conditions. These polymers, usually lipids, accumulate as storage materials (as mobile, amorphous, liquid granules) meant for microbial survival under stressful conditions. Bioplastics are made from a compound called polyhydroxyalkanoate, or PHA. Bacteria accumulate PHA in the presence of excess carbon source, similar to how humans accumulate fat deposits on their bodies after consuming excess food. Thus microbial PHA accumulators are microorganismal versions of Sumo wrestlers, accumulating storage biopolymers after consuming excess nutrients. Poly 3-hydroxy butyric acid (PHB) is the most common microbial PHA. Bioplastics are regarded as an environmentally responsible alternative to petroleum-based plastics. They rely less on fossil fuels, a non-renewable resource. They also are biodegradable when disposed of properly, reducing waste. Bioplastic products also result in a net reduction of greenhouse gas emissions because the plants used to produce the bioplastic material absorb the same amount of carbon they started with, thus displacing that carbon from being emitted into the atmosphere.
7 Bioplastics are synthetic materials and are sometimes criticized because their manufacturing and processing can result in environmental impacts. Any manufacturing process can be energy intensive, increasing GHG emissions if power is derived from fossil fuels. Other environmental impacts may include water used to irrigate crops, fertilizers and pesticides applied to grow agricultural feedstocks, and pollutants emitted from the transportation of crops and products to manufacturing facilities.

9 Collection/Gathering of Fish Scales Scales from the two varieties of tilapia will be collected together in Gapan wet market, San Lorenzo, Gapan city. Collected samples will be washed then dried under the sun until they are fully dried out. The samples will be melted with 250 milliliters (mL) of water using an LPG stove. Temperature will be kept at 100°C. This process will be replicated by using different levels of water-500mL, 750mL, 1L.
Accumulation of Biopolymer from Fish Scales The melted fish scales will be fermented in glass container(s), for three (3) months at a room temperature between 26-38°C. As fermentation takes place, growth of bacteria on the scales will occur, the same with the accumulation of polymer. After fermentation process, the fermented scales will undergo cell disruption, washing, centrifugation and drying to purify the biopolymer.
Purification of Biopolymer A. Cell Disruption The accumulated polymer will undergo cell disruption for one (1) day, specifically chemical permeabilization process in the DOST laboratory at CLSU. B. Washing and Centrifugation The disrupted samples will be subjected to washing process using a Liter (1L) of sterilized deionized water and will then undergo centrifugation process.
10 C. Drying After washing and centrifugation, scales will be dried through the use of a desiccator at the DOST laboratory in Juan R. Liwag Memorial High School. Sodium Hydroxide will be used as the main desiccating agent in the process. (Amount (g) of the desiccating agent will be determined after the mass (g) of biopolymer extracted from the fish scales.)
Production and Molding of Bioplastic The collected biopolymer will be brought at UBC Plastic Factory., Mendoza, Malabon, Manila and will be subjected to injection molding process to produce a bioplastic product. The produced bioplastic will be compared to commercial bioplastics which also undergone to injection molding in terms of: a. Physical Properties a. Color b. Odor c. texture b. Biodegrdability c. Durability
Statistical Tool This study involves Randomized Complete Block Design (RCBD) as the research design. The study will use Analysis of Variance (ANOVA) as statistical tool.
