I'm a diabetic, so blade disposal is easy. I put them with my needles for incineration. The drug store gives out free container, and I just return them back to the pharmacy. The disposal is for any biological sharps - so blades are legitimate. I know that others have asked for, received and disposed of nothing but blades. The container holds a *lot* of blades. They are usually about a litre (quart) or so large. I found a page that describes what my pharmacy considers 'sharps' for disposal:
"The disposal of used sharps is a public safety issue that concerns all of us. A ‘sharp' is any object that can pierce, puncture or cut the skin. Lancets, pen needles, syringes, knives, scalpels, razors, scissors or broken glass are all examples of sharps."
And to continue:
"Ask at your local Safeway pharmacy. A number of companies make sharps containers, two of the most popular being BD and Monoject. There is a nominal charge to obtain these containers. Safeway Pharmacy also offers their own sharps container produced in partnership with Lifescan Canada. This container is available free of charge at any Safeway Pharmacy."
I know this is a UK site (I am in Canada) but many of my UK diabetic friends have told me of a similar arrangement with your pharmaceutical supply companies. In the US you have the same disposal available at your Safeway Pharmacy or other Pharmacy.
