Aluminum cans take a great deal of energy and natural resources to process and transport. Aluminum begins as bauxite ore, is refined into aluminum oxide, and ends up as blocks of aluminum, a supply chain that can take it halfway around the planet. Next the blocks are heated and turned into large rolls of aluminum before being transported yet again. The sheets are stamped and manufactured into cans, which are then filled and distributed to stores. After weeks or months of travel and processing, the aluminum can is used for maybe a few minutes and discarded.
