haha yeah, well and the big thing at least for me is getting the Big pile wet.! The bigger pile the better, and turn in to out. Most compost bins are just that, a small bin, and only constitutes Cold composting which Does take 6-12 months to break down, and you lose a third of the original mass, And chunks of material left over.
Hot Composting--big pile at least cubic yard and carbon to nitrogen ratio of 50:1, nice and wet, provides same amount of mass, it will break down almost Anything including bones, and three weeks you have beautiful airy soil.!
Cold composting is common and good for confined areas, but time consuming. Hot composting you need the room and Is Very Laborious especially for those not accustomed to such hard work, and saves time. Though you can't "really" add more to it once it's going, but you could have a pile continually going if you wanted to tweak your turning and placement of the pile, or just have at least two piles which you use one to help feed the other with hot activator and make a new pile every 10 days with last weeks waste.
