Comparative study between taro (Colocasia esculenta) and green pea (Pisum
sativum) Bioplastic
Abstract
An experiment was conducted on the manufacturing of biodegradable plastics
using taro (Colocasia esculenta) and green pea (Pisum sativum) as the source of starch.
The starch was extracted by means of blending. The blended starch was then filtered
using coffee filter to separate the starch from the green pea deposits and cloudy water.
After being dried and pounded to fineness, the starch was mixed with water, followed by
some vinegar and glycerin. The mixture was cooked until it thickens and turns sticky. The
cooked mixture was left under the sun to dry.
The manufactured plastics were tested for its biodegradability and water
susceptibility. The results yielded from experimentation shows that a decomposable
plastic can be produced from taro starch starch but a plastic was not produced from green
pea starch.
