Refining / Processing
Part Fabrication
Subassembly Manufacture
Vehicle Distribution
& Use

Cars are transported to the dealers, then purchased and utilized by customers.
Vehicle Disposal
Decommissioned vehicles are brought to facilities for parts removal, then they are shredded to capture materials for recycling. The remaining automobile shedder residue is most often landfilled.
Iron ore and bauxite ore are mined from the earth to create the materials needed to build the car. Coal and petroleum, which provide the energy to refine the materials, is also extracted.
Iron ore is refined and processed to make into pig iron and then steel. Bauxite ore is refined to produce aluminum alloys. Similar processes are undertaken for plastics and glass.
Metals are cast, rolled and/ or shaped into individual parts.
Several parts are assembled to make a subcomponent for the car.
