What happens to the waste at the airport waste facility?

Have you ever thought about what happens to your old tire when you get a new one? Or the washing machine they took away when you got a new one? Or even the cars that get written off? Well most of them end up at the airport waste facility.
Stacey Simpson has been working in the management waste facility for about 20 years. He says the land here is all man made, built from trash. Every working day he sees over 100 trucks entering the facility. Old boats get sunken there and the plan is just to cover and build, but the land itself can never be built on.
There is a limit to how much of our clear waters can be used to bury our waste. The question is - how much longer can we continue to hide our waste? How much space do we have left?
