Abstract:
Due to the negative impacts of fossil fuel plastics, the development of bioplastic is
essential for both industrial and commercial levels. Researchers have developed various
starch-based bioplastics tea waste can be used as raw material and the newest and greener
product for different applications. This work mainly targeted to investigate for feasible
synthesizing starch-based bioplastic with addition of tea waste. In this study for the
analyzing purpose the prepared bioplastic was subjected to thickness measurement, soil
biodegradability test, moisture content test, water absorption test and visual analysis for
colour changes. The synthesized bioplastic was assessed by the soil burial methods in two
different depths. The results have shown that the degradation rate was higher so it
exhibited faster degradation in soil mixture. And also, Physical properties changing were
indicated in the Soil burial test and on the l4th day some cracks were observed on the top
of the bioplastic sample and broken in 2nd week of experiment. The colour of the bioplastic
sample also changed and became darker than the initial colour. After 7 days of the
moisture content test the bioplastic samples showed 29.94% moisture loss. Through this
greener, biodegradable and sustainable production, represent a step toward the
development of industrial and achieve reduction in the negative environmental impacts.
