I determined which of three commercial decomposable plastic biodegrade faster, and which of twelve environments breaks down the plastic the fastest. Secondly I made my own bio plastic and compared it to the commercial bio plastic that broke down the fastest in the previous experiment. I buried the commercial bio plastics in 12 different locations for a total of two months, observing them every three days. I planted my bioplastics for two weeks in two different locations, observing them every three days. I also devised a strength test to evaluate the commercial and homemade plastics before and after.
