Step 1 - bauxite is mined in Australia
Step 6 - metal ingot cured and shipped to Germany
to be rolled
Step 11 - can is lacquered and coated inside
Step 2 - bauxite is trucked to plant for chemical
processing 1 ton ore gives 1/2 ton Aluminum Oxide
Step 7 - ingot is heated to 900?F and rolled
into coil
Step 12 - cans are palletized, stored, and
shipped
Step 8 - coil is stored and cold rolled into
sheet
Step 14 - bottler cleans and fills with product
Step 3 - shipped to Norway for processing
Step 9 - sheet metal is shipped to
England, punched and formed into cans
Step 15 - cans are packed in promotional
boxes, palletized and shipped to retailer
Step 4 - oxide sits at smelter site for up to 2
months
Step 10 - can is washed, dried, primed and
painted
Step 16 - Can is purchased, contents consumed
within a few minutes and is thrown away
Step 5 - 2-hour smelting reduces 1/2 ton of
oxide into 1/4 ton of metal
