I'm pretty sure my tea bags are paper, and have always been paper. It's the more recent "pyramid" shaped tea bags that I think are made of plastic. The most recent change to my tea bags was to remove the staple so they could go in organic waste.

You'd be surprised how paper-like the plastic bags appear to be.

Could try burning a tiny piece and check how it behaves and smells.

I doubt the advice would be to throw them in the organic waste if it was plastic.

Some plastics can go in the organic waste bins, such as the organic waste bin bags.

While they can go in the organic waste bins, they still get sorted out at the end because they don't degrade fast enough.

Sure and it might be that the teabags are also being sorted out.

Why can't staples go in organic waste? They go into my compost pile and will rust. Iron is like 5% of average crustal rocks and is abundant in soils.
