How can I safely dispose of butane cans?

To safely dispose of butane cans, follow these steps:

1. Check if the can is completely empty by releasing any remaining gas in a well-ventilated area.
2. Wrap the can in a plastic bag or container to prevent leaks.
3. Take the can to a hazardous waste disposal facility or a designated drop-off location for proper disposal.
4. Do not puncture or crush the can, as it may still contain flammable gas.

By following these steps, you can safely dispose of butane cans and prevent any potential hazards.
