Garbage or Recycling Container
Throw out metal or rigid plastic garbage or recycling containers with your recycling items. Put a label on the container that says "Sanitation, please take this can away" so that the Department of Sanitation knows to take it.
Printed materials that come with prescription medication should be referred to for specific disposal instructions.
Most prescription drugs should be mixed with an undesirable substance (such as used coffee grounds or kitty litter) and put in impermeable, non-descript containers (such as empty cans or sealable bags) before throwing them out in the garbage.
Printer Ink and Toner Cartridge
You can mail ink and toner cartridges back to the manufacturer or throw them away with your regular garbage.
