What happens to my psoriasis treatment syringe

[Fred]

Does anyone know what happens after we have used our single use syringes and am I doing it right ?

Once I'm finished here is what I do.

1. The swab I use to clean the skin goes in the bathroom waste bin.
   
2. The cardboard box, inner packaging, leaflet and needle cap I put in the recycle bin.
   
3. The syringe goes in my yellow sharps bin.
   

#1 I assume is going to landfill. Ok it's only one little pad, but am I right putting it in the general waste ?

#2 I'm guessing those can all be recycled, but should I put the cap and inner packaging in as they have been near the treatment could they contaminate ?

#3 When full I take my bin to the pharmacie and they give me a new one. But what happens to all those syringes ?

Thoughts ?
