Effects of glycosidic bond between complex carbohydrates and glycerin on degradability and durability​

"The purpose of this project was to determine glycerin’s effect on the flexibility of bioplastics. Bioplastics in their current form are not viable because they are still to brittle and flimsy. Bioplastics are known to be too brittle and non-cost-efficient but the only way to decrease the plastic pollution in our oceans is to find alternative that are cheap and degradable. To determine glycerin’s effect on the flexibility of bioplastics I began by creating multiple batches of bioplastics each with a different amount of glycerin added. After waiting three hours I measured the cracks formed on each of the bioplastics using a software called ImageJ. The bioplastic with the least cracks per square inches only had three to four drops added and any bioplastics with 5 or more began forming more cracks per square inch. Hopefully, with my data, future productions of bioplastics will be created with the correct ratio of glycerin to starch allowing bioplastics to be more flexible. "

  1. I like how the plastic is biodegradable. The study of better helping the planet or something that benefits the world is very admirable.

  2. This is an amazing project! I love your experimental design and your graphs are very easy to read. Your slide deck looks very nice as well. Good luck!
