First off, I'd say you don't need to take the time to tear open all those tea bags. We don't drink much tea but when we do, we just toss the whole bag (leaves, bags, string, tag, and even the little package, if its paper) into our kitchen compost bin with all the rest of the "green" waste. I've been successfully putting my coffee grounds AND filters in my compost pile for a couple of years now. The filters seem to decompose just as fast as the rest of the typical kitchen "green" waste. I have never seen any of them in the pile without seeing the other stuff too.
As you know, egg shells are great in the pile, too. I try to crush them up but probably half of them are just cracked in half. Crushed or not doesn't seem to slow decomposition.
I also put shredded junk mail in the pile too. Nothing too shiny or heavily printed, but letters, envelopes and stuff like that. I add it when I'm turning the pile and mix it in until it "looks" like any more would be too much, if you know what I mean. :)
Peanut shells have also been no problem, but those I did see when I sifted the compost to add it to the garden this spring. I figured it just added more "fiber" to help keep the soil from clumping. By the time I harvested, the shells seemed to be gone.
We're physically doing our best in our own little "more-urban-than-suburban-but-definitely-far-from-rural" homestead. I daily long for the day when we move to our own self-sustaining, off-the-grid homestead. Being dependent on government service like water concerns me greatly. Plus all the crazy covenants, rules, laws, and other restrictions on anything that might facilitate a little independence like no chickens and restrictions on allowable garden size, plants, and location, etc is a difficult and frustrating way to live. The neighbor can have several wild pit bulls that can rip my head off but I can't have a couple of hens for "city" fresh eggs or a tomato plant in my front yard? :O
Anyway, I admire your courage and commitment to your lifestyle and appreciate sharing your experiences and knowledge.
