As anyone who has ever owned a propane-powered grill knows, those tanks don’t last forever. They have a lifespan of about 15 years, give or take, and once they hit that expiration date, they need to be replaced.
But what happens to all those old tanks? Do they just get thrown in a landfill somewhere?
Actually, no. Most propane tanks are made of steel, and steel is recyclable.
So when a propane tank reaches the end of its useful life, it can be taken to a recycling center and melted down to be used again.
But what about the propane that’s still in the tank? That can’t just be recycled along with the steel, right?
Wrong. The majority of propane tanks are actually purged before they’re recycled.
Purging a propane tank is a process of removing all the gas from the tank so that it can be safely recycled. There are a few different ways to do this, but the most common method is to use nitrogen.
Nitrogen is an inert gas, which means it doesn’t react with anything. So when it’s pumped into a propane tank, it displaces the propane gas and forces it out of the tank. Once the tank is purged of all its gas, it can be recycled without any risk of explosion.
