E144 - Are postage stamps recyclable?

Are stamps recyclable? Used stamps can be donated to charities, which sell collectable stamps to raise funds, although everyday stamps have very little value. If you're saving stamps, trim around them carefully, leaving about 1cm of envelope attached. As for stamp books, they're likely rubbish. Self-adhesive stamp backing paper is thought to be coated with silicone so stamps can peel away easily. Like greaseproof paper, this silicone coating can contaminate paper recycling, making the backing sheets unsuitable for recycling.
