I’ve recently had to replace my metal Monzo Premium card and wondered if there was a ‘best practice’ way of destroying the old card before disposing of it?
With old plastic cards I just used to shove them through the shredder but obviously not an option with the metal card!
I believe Monzo offer to recycle them for you if you send it to them. Check the help section in app?
They do indeed 
That just says they dispose of it safely, not recycle it.
If they’re recycling it, you’d think they’d say so. It’s a selling point for metal cards. They’re far more recyclable than plastic cards, and if Monzo aren’t doing that, it’s a pretty big blunder IMO.
Honestly starting to get a bit peeved with folks on here misrepresenting Monzo’s claims.
I use my old metal cards as scrapers for my fishtanks - very effective.
Surely metal would scratch the glass 
Melt it down, forge it into a trolley token #lifehack
It’s only steel. And probably not graded like iPhone’s steel is (which isn’t strong enough). So probably not. Won’t be hard enough to scratch glass.
No scratching ever.
A lot of fish tanks are made of acrylic now which is a lot easier to scratch. I wouldn’t use it on those types.
It’ll scratch acrylic but the post I replied to was talking about glass not fishtanks.
Just a little update for anyone who may find this thread useful in months to come - I asked Monzo via the Help section in the app and they advised me to send it back to them in an envelope (no need for a stamp) to FREEPOST, MONZO RECYCLE. So it does indeed at least give the impression they do recycle them.
