What to do with medical sharps (syringes and needles)
Medical sharps, such as needles, syringes, lancets and injection pens, are not recyclable.
To protect sanitation workers or anyone who handles your trash, they should be put into a tightly closed, puncture-resistant container such as a detergent bottle, and labeled “Caution: contains sharps!”
There are also commercial mail-back programs for sharps.
