1 Introduction
Plastic bottles, plastic spoons, plastic packaging, plastic bags… we use a lot of plastic. Plastics are made from polymers, which are super long chains of atoms. We love them because they’re cheap and super sturdy for how light they are. The problem is that they’re so sturdy that, after we throw them away, they can sit around in a landfill for a million years. Almost all plastics we use come from petroleum products, but recently more is being made from corn starch which has a compact structure which can be used as a plastic. Since corn starch is often used and cannot be easily found in Dipolog City, we thought of another replacement for it that can meet its standards and can easily be found, which is the cassava starch.
The cassava root is long and tapered, with a firm, homogeneous flesh encased in a detachable rind, about 1mm thick, rough and brown on the outside. Commercial varieties can be 5 to 10 cm in diameter at the top, and around 15 cm to 30 cm long. A woody cordon runs along the root 's axis. The flesh can be chalk-white or yellowish. Cassava roots are very rich in starch, and contain significant amounts of calcium (50 mg/100g), phosphorus (40 mg/100g) and vitamin C (25 mg/100g). However, they are poor in protein and other nutrients. In contrast, cassava leaves are a good source of protein, and are rich in the amino acid lysine, though deficient in methionine and possibly tryptophan. These components are components of biodegradable plastic. (http://www.studymode.com)
