Here is an interesting new compost ingredient, courtesy of having an under three year old in diapers at night and training pants in the day. The little beads of water absorbing material are essentially the same stuff that premium potting soil mixes use, to basically slurp up excess water, then slowly release it over time. I collect a couple of poop free diapers, wet them fully with water, then cut open one end and squeeze the contents into one of the composting bins. This way I actually compost much of the diaper, unlike the City of Toronto that picks diapers up in their green program, and then has people hand pick them out to send them to the dump! What a load of crap that is... literally!
