Compsting isn't stinky, hard, or time consuming; you shouldn't have to buy or make special bins or powders or barrels. It should be (and IS) the most natural thing on earth, so don't make it more complicated than it has to be! Read on...
Step 1: Find a location
Step 2: Dig a hole
It is very efficient to pre-dig and do a long trench.
Step 3: Set displaced dirt aside
Step 4: Save scraps or yard waste
From what I understand, it is dangerous to use feces of animals that are capable of eating meat (so not even feces of vegetarian dogs).
I know people who put used facial tissue or paper towels in there. I'd also stay away from newspaper and other printed papers; again, think about what goes into the material and make your own choices.
Step 5: Cover up the biodegradable material with the reserved dirt
Step 6: Let it be!
When we trench, I'll plant small seed flowers or a 'green manure' crop on top of it the first year and rototill it in the next spring. Read more about green manure crops; they're amazing.
Step 7: NOTE: When you live in a cold climate
To do this, you'll need to do three things:
-make a trench before the ground freezes in the fall/winter
-put down an old blanket to keep snow out of the trench or shovel the snow out of the trench
-and if you want to cover the compost before spring, insulate the reserved dirt so that it doesn't freeze. I use 6-10 inches of fluffed straw. Fluffy leaves that don't compress or lots of grass clippings work. You won't need to cover up the biodegradable material until spring, but it is up to you.
