See when ye pick yer nose which bin should the resultant crispy/wet bogey go in? The regular bin, or the food waste bin? This recycling malarkey is confusing.
I dunno, but whenever I see the word "question" on its own, the following lyrics spring to mind: "Tell me what you think about me. I buy my own diamonds and I buy my own rings." Every single time, without fail. I've had a think about your OP, and I'd go for general waste. If I was feeling posh.

If you have a small herb patch or veggie garden then why not collect your nasal detritus and feed it back to mother earth. We are stardust, we are golden.
