We recently got ourselves a garden (we didn’t steal it or anything, just moved somewhere with one) and I’ve been looking into what you can compost and what you can’t compost. I’d like to compost my used tea and teabags (there’s quite a lot in our household, so I feel it’s worth composting them all) but came across the rather startling revelation that not all tea bags are 100% compostable. Most contain a percentage of plastic called polypropylene and this will be left behind if you pop them on your compost.

Loose leaf tea wins again!
