All steel products can be melted down and recycled into any other steel product. If you're not sure whether a can is made of steel, there's more than one way to tell. First, check for the steel logo somewhere on the can. More and more companies are putting the logo on cans. Then, if you're still not sure, test it with a magnet - if it sticks, it's definitely steel.
Tin cans are actually steel with a thin tin coating.
The steel used to make food cans, like soup and coffee, is high-quality steel which is an ideal raw material for making new steel. Each year, more than 35 billion steel cans are produced in the United States, and each one is manufactured using about 25 percent recycled steel. It's all steel and it's all recyclable. You may have seen steel recycling ads on San Diego billboards or heard them on the radio. That's because I Love A Clean San Diego County, Inc. is working with the Steel Can Recycling Institute in Pittsburgh to increase public awareness of the recyclability of steel cans.
