All EMPTY steel and aerosol cans
Lids: If the lid is steel, make sure it is secured inside the can so that workers are not exposed to sharp edges. If the lid is a different material, it must be larger than 2 inches and loose from the container to be recycled. Any lid under 2 inches should go in the regular garbage because it gets stuck in the sorting machine at the recycling facility and can't be processed.
