Biodegradable Plastics

The students in Mrs. Massic’s Materials & Processes class made biodegradable plastic/polymer from glycerin, vinegar, corn starch and water. The student pictured is Eli Williams, who attends Spanish Fork High. Eli commented, “My polymer appeared opaque and then clear. It had the viscosity like a smooth paste. I learned that plastics decay slowly, but biodegradable plastics have a faster rate of decay. [So by making this type of polymer] we won’t have as much plastic in the oceans.”
