Plastic is good for the environmental sustainability. From energy saving potential, intrinsic recyclability and energy recovery options, plastic also makes the positive contribution. I made this project by using the sugar box from a brand named Sugarfina. I really like to eat Sugarfina’s candy, so I had many candy boxes after I ate the candy. I found out the candy boxes is beautiful. Then I have some questions:What is these candy boxes made out of? Can candy boxes recycled? Then, I found out the candy boxes are made by plastic. And this type of plastic can be recycled. Then, I have an idea about burning the plastic boxes and to see what will happen. When I burned the plastic boxes, it produced a sharp odour. So I want to use the polyfill to show the sharp odour and to create a sense of explosion.
