Volcano garbage disposal

A few years ago I was in Hawaii for Thanksgiving. It was my first time to go there and I really enjoyed it all tremendously.However, I was left with one burning question: where do they dump their scrap cars? I rode on one that was despirately rusty and decrepit. Has anyone ever thought of dropping them into the volcanos? Islands by definition have small land mass. Why not throw old cars and other trash into an active volcano and increase the land mass that way when it erupts recycled as molten lava?
We need a volcano over here...
