Microplastics detected in chewing gum – expert warns: “Can be harmful to health’. Chewing gum is made from petroleum-based plastics and is 50 to 70 percent sugar.
Plasticizers, humectants, emulsifiers, colorants and fillers are also added. The plastic parts are not biodegradable and should not simply be spatlessly onto the street. Spit out chewing gum in the trash, but rather dispose of it in the waste bin.
