The spent herbal ingredients and the tea bag itself need separate consideration before going into home compost. Even when the plant contents are suitable, the filter or sealing material may not break down under garden conditions.
Check the actual bag
Look for an explicit home-compost instruction for the product you have. A general biodegradable claim or an industrial-compost certification is not the same thing. Your compost heap does not necessarily reach the conditions used in a commercial treatment facility.
If the bag material is uncertain, a practical option is to open the cooled bag, add the spent plant contents and dispose of the filter according to the supplier's guidance. Remove tags, staples or strings that are not covered by a clear home-compost instruction.
Mix, rather than making a wet pile
A compost heap needs a mixture of materials. Scatter modest quantities of spent tea among your other compost ingredients rather than repeatedly leaving a dense, soggy layer in one place. Follow a reliable home-composting guide for managing the whole heap.
Avoid adding packaging just because it looks like paper. Coatings and seals may change the appropriate disposal route.
Is the food-waste bin different?
Yes. A council collection can use a treatment process that differs from a home heap. Check your own council's instructions for tea bags rather than assuming advice from another postcode applies.
A useful routine is to let the bag cool, separate uncertain packaging and put each part in its appropriate place. Once you know the materials used in a favourite product, you can repeat that routine without trying to judge every used bag by how it looks.
