Toner consists of a dry, powdery substance that is electrically charged so that it adheres to a drum, plate, or piece of paper charged with the opposite polarity2. Common ingredients in toner are styrene acrylate copolymer, iron oxide, polymethyl, methacrylate, carbon black, polyester resin, amorphous silica, dyes, polypropylene, and waxes.3 As we see there are a lot of different ingredients, but styrene acrylate, carbon black and styrene copolymer, along with polyester resin are the most commonly used. Out of all of them, carbon black is the most dangerous compound. Carbon black, which the International Agency for Research on Cancer has classified as a 2B carcinogen, or "a dust that is possibly carcinogenic to humans4. Carbon black is a key pigment. The synthesis of carbon black is an energy intensive process, as it requires burning hydrocarbons at extremely high temperatures at approximately 2000 degrees Celsius in order to obtain elemental carbon.5 Styrene acrylate copolymer is makes up approximately 80% of the mixture that is used in toners. This is classified as a resin and is the key ingredient in the xerographic process. Styrene acrylate copolymer is manufactured from a process called a batch emulsion polymerization.
