What's in my compost bin

I have several composting areas in my yard. I have a large area for leaves and twigs and two smaller bins for kitchen waste, weeds, paper, and pet bedding (and the associated manure). This compost bin is right outside the backdoor of my house.  It's very convenient for disposing of vegetable scraps and other kitchen waste.

Frostbitten nasturtium plants, tomatoes, romaine, potting soil, and leaves are a few of the things at the top of my compost pile right now.
