Mike first heads off to Las Vegas to work at an old fashioned printing press making lithographs of himself for the official Dirty Jobs poster. Mike then goes to Lincoln, CA and helps make large scale terra cotta building sculpture pieces from recycle... (more)d terra cotta sewer pipes. Finally, Mike visits a garbage processing plant in San Francisco where food and assorted scraps are passed through a rolling cylinder and "digested" to make a methane gas energy supply.
