City At Sea

Thousands of hard-working Sailors live at sea for months at a time. So how does the Navy manage this "City at Sea" in an environmentally responsible manner? 

Let’s see what it takes to operate this massive, floating neighborhood without putting any plastics into the sea.
  • Sailors sort all of their trash in order to separate plastic from other waste streams, such as paper, metal and biodegradable items.
  • All plastics are brought to the ship’s waste processing room  where they are run through a shredder, which breaks them into smaller pieces and reduces volume.
  • Plastics are then put into a powerful machine that simultaneously compresses and melts them into a solid disk, further increasing the volume reduction.
  • Disks are placed in odor barrier bags and transferred to a supply ship or held in storage until the ship returns to port.​
