Recycling: tin and lead
Recycling of tin and lead, particularly the latter, takes place on a huge scale. The tin used to coat steel cans is recovered using specialized detinning processes. In Europe, about one-third of tinplate produced is currently recycled, while in the US in 2001, 58% of tin-plated steel cans were recycled. Lead–acid storage batteries represent a major source of metal that is recovered. In 2001, ≈78% of refined Pb manufactured in the US originated from recycled metal, much of it (_1 Mt) coming from spent batteries from vehicle and industrial sources.
