Plastic materials derived from plants or green plastic in the country ahead of the start-poli laktat acid (PLA) and poli-hidroksi alkanoat (PHA) through the fermentation process, but the processes are still expensive, so the need to look for other ways. A natural polymer derived directly from the plant is natural rubber, cellulose from cotton, wood products, bamboo, rami, plants, fruit (pineapple, banana). Polymer is another source of marine and animal sources, such as shrimp, leather, crab skin, sheep wool and silk worm. Generally these products environmentally friendly.
