Have a needle clipper? When the needle clipper is full, it can be disposed of according to your state or local regulations. More information can be found here.
If a trash collector is reluctant to collect a red sharps container, refer them to your state waste agency.
Sharps that retract after use, or are very small, should be disposed of like all other sharps.
If you would like to bring your sealed container to a community sharps disposal program, there are drop-off locations in Buncombe County, Cumberland County, Durham County, Henderson County, New Hanover County and Orange County.
