CHAPTER 1

INTRODUCTION

Background of the Study
Solid waste management is increasingly seen as a major issue in the country due to high rates of urbanization and increasing per capita solid waste generation with greater affluence (Petnamsin, et al., 2000). A major component of solid waste is resin based plastic. Plastics posses many properties such as water resistance and long life, that makes them perfect candidates for packaging. Unfortunately, the properties that make this product suitable for packaging also are the major cause of the environmental problems related to packaging. Given the wide use of plastics, the magnitude of the environmental problem is large and long terms. The choices for dealing with this waste are limited as incineration of plastic polymers invariably results in the generation of toxic emissions (Srorith, et al., 2000). The only visible solution is to bury the material in landfills. However, this approach is also limited because of the resistant nature of plastic to biological degradation.

Jackfruit Artocarpus heterophyllus Lam. is a popular fruit-crop that is widely grown in tropical areas. Often, its seeds are discarded because of the preferred well-flavored yellow sweet bulb for consumption. The seeds have high carbohydrate and protein content, hence, an abundant source of starch (Kurian, 2010). Starch is identified as a key natural product for the production of biodegradable plastic (Pranamuda, et al., 2006).

Based on the above information, the researchers decided to do research work on starch-based biodegradable plastic from jackfruit seeds. Henceforth, there is a need to establish the additive property of starch from jackfruit seeds as scientific basis for its use in the production of biodegradable plastic.

Objectives of the Study
The study will aim to find out if jackfruit Artocarpus heterophyllus Lam. seeds can be a main component in the production of biodegradable plastic. Specifically, the study will 1. determine the efficacy of starch from jackfruit A.heterophyllus Lam. seeds at varying concentrations as additives in the production of biodegradable plastic. 2. compare the mechanical properties between the produced biodegradable plastic from starch of jackfruit A.heterophyllus Lam. seeds, and commercially prepared plastic, polyethylene in terms of tensile strength, flammability, soil biodegradability and air test. 3. compare the effects of acids and bases and organic solvents between produced biodegradable plastic from starch of jackfruit seeds and commercially prepared plastic, polyethylene.

Hypotheses of the Study
The following hypotheses will be put forward:
1. There is no significant difference in the efficacy of starch from jackfruit seeds at varying concentrations in the production of biodegradable plastic. 2. There is no significant difference on the mechanical properties between the produced biodegradable plastic from starch ofjackfruit seeds and commercially prepared plastic, polyethylene in terms of tensile strength, flammability, soil biodegradability and air test. 3. There is no significant difference on the effects of acids and bases and organic solvents between produced biodegradable plastic from starch of jackfruit seeds and commercially prepared plastic polyethylene.

Significance of the Study
The results of the study would be beneficial and helpful to the manufacturing plastic industries because it would relieve negative effects of overproducing plastics. By changing its raw materials and components, commercial plastic may be improved so that it would become biodegradable while retaining its good quality. Moreover,this component from starch of jackfruit seeds would help in the natural decomposition of plastic raw materials. Thus, a convenient way of minimizing waste management problem in the country, more so, the high demand for plastics would give the world the hazard of garbage problem, therefore, utilizing starch...
