Cans are sorted, baled and taken for crushing into large blocks, and sometimes shredded for reprocessing. Melting removes all inks and coatings before metal is made into blocks (ingots), which can be huge, 2 x 8 metres and 60cm thick, and weigh as much as 20 tonnes. Each one contains about 1.6 million drinks cans. Ingots are sent to mills where they are rolled into sheets from 0.006mm to 250mm gauge. This rolling adds strength to the pure aluminium which is then used to manufacture new aluminium products such as car parts and cans.
