Garbage Mountain

Mammoth machines. Trash piled twenty stories high. Man and technology in a battle against a tidal wave of waste. Uncover the gargantuan world of garbage at America's largest active Mega Dump: Puente Hills, California. Most landfills take in 2,000 tons of trash a day -- this one processes 2,000 tons an hour. How does it do it? With mega machines and mega ingenuity. Take a spin in the 120,000-pound Bomag Compactor, with its 55-inch garbage-crushing steel wheels. Power up with methane gas... Puente Hills powers over 100,000 homes and a fleet of vehicles with their landfill gas. And find out what happens to your trash when you're not looking. You're going behind the scenes at LA's dirtiest suburb. Call it big, call it nasty, but don't you dare call it just a hole in the ground!
