Rinse each aluminum can so there is no sticky soda left. Next, crush the cans to save space in the bin. Put them into a clearly labeled container so they are not mixed with trash. Recycling aluminum saves a lot of energy; making a can from old metal uses far less electricity than making one from raw materials. At the factory, the cans are melted and rolled into new sheets of metal. Finally, trucks deliver these sheets to make new products. These steps help cans become new metal instead of trash.
