Garbage Pits
these huge, open pits were located all over the planet Coruscant, and were two ways in order to eliminate the more than a trillion tons of refuse produced on the planet each day. Most organic materials - food scraps, paper, light metals, and plastics - were actually consumed deep within the pits by garbage worms. Materials which were too toxic to incinerate were placed inside sealed containers and scheduled for transport. The energy from plasma generators was used to power an acceleration field which was used to fire the containers into low orbit. Traffic throughout the planet's cityscape was re-routed around the pits, so that the speeding containers didn't inadvertently destroy a taxi of liner. The containers in low orbit were collected by specialized tugs, and moved to one of Coruscant's moons for more permanent storage. The pits themselves were protected from unwanted intrusion by a series of shields and energy barriers.
