Knowingly avoing the question. I'm sorry. In my region (Flanders), they are asked to be thrown in the non-recyclavle trash, which grings as much gears with me as with you. I also upvoted a peer comment calling out the microplastics which are liberated from the mesh each time it is heated. Far be it for me to tell other people how to prepare their tea, but I'd like to caution you for the (added) microplastics.
Glad you're trying to make an effort to preserve our environment.
My husband bought sinilar tea bags. I open them up prior to use and place the content in a stainless steel tea egg. I'm sure he bought bags by accident as we usually drink loose tea.
