Sweet wrappers should go in your rubbish bin.
Although they're shiny and look like foil, they're actually made out of metallised plastic film, a material which can't be recycled yet.
Do the scrunch test!
An easy way to find out if something is made from foil or metallised plastic film is to do the scrunch test. Simply scrunch the item - if it stays scrunched up it's foil and can be recycled; if it springs back it's probably metallised plastic film and not recyclable.
