Implication

This research optimizes biodegradable bioplastics in taro starch composites, highlighting environmental benefits.

Key Points

  • The study aims to evaluate the impact of material ratios and plasticizers on the performance of taro starch-based bioplastics.
  • Combined taro starch with carrageenan and glucomannan at two different ratios.
  • Used three types of plasticizers: castor oil, stearic acid, and egg white, each at 1 gram.
  • Measured mechanical properties and biodegradability of the bioplastics.
  • Bioplastic with a ratio of 25:75 of taro starch to carrageenan and 1% castor oil showed the highest tensile strength at 18.33 MPa.
  • Elongation at break was recorded at 4.96%.
  • Complete biodegradation occurred in 6 days under test conditions.
