Abstract

Bio-based plastics are a great alternative to replace traditional plastics, which are often composed of petroleum products. Bio-based plastics are also sustainable and eco-friendly alternatives compared to petro-plastics, which are non-renewable and non-biodegradable. Food waste especially rice, which is rich in starch, has been considered as a potential feedstock for producing environmental friendly biodegradable plastic. By using rice starch to make biodegradable plastic to be able to help contribute useful things that may help in lessening garbage pollution. There are 3 different types of leftover rice starch film that had been test. The effectiveness of bio-based starch film is evaluated by two types of testing which is biodegradability testing and tensile testing. The result can indicate that leftover white rice have the higest of strength compare to leftover fried rice and leftover nasi beriani which had been made to bio-plastic. For the result of soil biodegradable test, its involve 3 different types of leftover rice starch. The degradation of 3 different type of samples leftover rice shown 100% successful after 8 weeks and its achives and classifies as sucessfull on the term of biodegradable according the ASTM related. For the rest of the rice samples, additional material was also found to influence and affect the rest of the rice starch in mechanical properties and physical. In conclusion, the remaining white rice has the potential as an alternative to commercial packaging bio-plastic after it in the synthesis and having regard to the results and the mechanical properties and biodegradation.
