REVIEW OF RELATED LITERATURE The growth of the production of bioplastics has increased because of the other misfortunes of regular petroleum made plastics—like the time it takes for it to be disposed, or how it is only a trash that is polluting our environment. It is stated in sciencelearn.org’s (2013) article about bioplastics that a bioplastic is only a broad term, using only to describe a wide range of plastics that are either biodegradable or derived from renewable resources, or both. Although it is said that bioplastic is merely a term, greenhome.co’s (2012)

The presented materials are rice starch and monggo bean starch. These starches are not commonly used to create a plastic, although it is possible for them to be used because of the two Finnish researchers who created a rice starch bioplastic with results having the product highly strong and transparent (plasticnews.com, 2014). Monggo bean starch can be also used, and is possible for modification just in case (Handbook of Bioplastics and Biocomposites Engineering Applications, 2011). It is hypothesized that the two starches can be combined in order to produce the said bioplastic, and can be highly strong and reliable than other made bioplastics. But since there are no articles or past studies about this topic, the first main goal is to determine whether the starches are really suitable as a combination. First of all, like the one stated in plasticnews.com, the rice has been modified a lot by the researchers in order to produce such product. Hence, it can be possible that in this study, a modification of the materials needed is necessary. As for the monggo bean starch, there is a high chance that it be modified as well, since the real purpose of the said starch was to produce noodles, particularly in Asian countries, as said by Thao (2011). Moreover, the two will somehow undergo a particular process in order for it to be processed as a unique

Since the properties of the rice and monggo beans individually suggests that the two have different purposes, and commonly thinking, may not be suitable for combining because there’s more properties to be altered by different ways, not only those properties stated in the Handbook of Bioplastics. For example, the tensile strength of the plastic, stress, strain, elongation, and stiffness; this can be tested by the tensile tests, according to Ferhat Avdić
