1 Lauren, Jake, Ben, Fadil

2 Aluminum: Primary source is bauxite, which is extracted from the Earth Polycarbonate: Made from crude oil and natural gas Lacquer: Made from acrylic Gold: Mined Dyes: Made from petroleum products ACQUIRING MATERIAL

3 Bauxite is washed, crushed, dissolved, filtered, and harvested into a substance called alumina. Alumina is then smelted into aluminum. Crude oil and natural gas are combined with other chemicals in a manufacturing processing plant. PROCESSING

4 An injection moldering machine creates a 1 millimeter thick piece of carbonate, which will serve as the core of the disk. Polycarbonate shape is modified. It is then placed under high pressure, while then a stamper places tiny indentations holding digital information. These indentations are read when the CD is played in a CD player. The plastic molds are then placed in the “metallizer”, which places a thin reflective metal layer (commonly aluminum) by the “sputtering” process. The playback laser reads this information off the reflective surface. Lacquer is then placed as a coding layer to protect the CD from external damage. MANUFACTURING

5 The CDs are then packaged in a plastic case. Sometimes they might be in cardboard boxes with plastic shrink-wrap covering. PACKAGING

6 Plane, truck, or rail which requires fossil fuels for energy. This in the end contributes to climate change. TRANSPORTATION TO THE CONSUMERS

7 Used to hold information, music, play Playstation one games. The good stuff… THEIR USES
