Can You Recycle Window Envelopes?
That little plastic window on your envelope - does it stop the whole thing from being recyclable? Here's the answer.
Can you recycle window envelopes?
Yes, in most cases. The majority of UK councils accept window envelopes in your household paper and cardboard recycling. You don't need to remove the plastic window.
Quick answer
Yes, you can recycle window envelopes in the UK. Modern recycling facilities filter out the small plastic windows during processing. Most councils accept them in your paper and cardboard bin without needing to remove the window.
What about the plastic window?
The plastic window is typically made from a thin film of polypropylene or glassine. During the paper recycling process, this is separated out and removed.
The amount of plastic in a window envelope is tiny compared to the recyclable paper, so it doesn't contaminate the batch.
