The secondary advice on government websites in Australia is to dispose of sharps in sealed off metallic containers (tin, aluminium cans, etc). You should be fine, 90% of material sent to recycling facilities is trashed anyway based on contamination.
(side note: Had to dump my ex because he hated that I drank more than once a week... would shit himself now if he saw my drawer of paraphernalia and vials. Count yourself lucky

Fucker was going through my emails and trash too.
IMO True love is someone that will pin you in the ass and ask no questions.)
