I've read all three of Carol Steinfeld's books on waste management.
The Composting Toilet System Book was her first, and it is basically a buyer's guide to the choices available to homeowners in 2000, when it was published.
It covers the range of technologies and products that are available. One page devoted to bucket collection ala The Humanure Handbook. Also has some examples and information about greywater treatment systems. This is meant to expose the reader to the full spectrum, so it doesn't offer in-depth information about any of the systems. Still interesting.
Her 2004 book, Liquid Gold: The Lore and Logic of Using Urine to Grow Plants, spells out the ridiculousness of flushing human liquid wastes through wastewater treatment- being a hazard to the environment and costing money (and clean water!) to neutralize while farmers are paying for nitrogen and phosphorus fertilizers produced with imported energy. It discusses old and new techniques to recover this resource safely and productively. Programs in Sweden, Denmark, Wales, Nepal and Mexico are on the cutting edge. A sustainable future may include peeing into new containers rather than a bowl of water. Photo examples of plant growth using urine as fertilizer are compelling, and safety concerns are included.
Her 2007 survey, Reusing the Resource: Adventures in Ecological Wastewater Recycling, is much more ambitious. Here, she collects in one place a huge variety of current systems of managing wastewater, from residential to municipal to industrial. Though not exhaustive, it covers systems from around the globe, and offers a brief understanding of the importance of the trend to managing our wastewaters more organically. Enlightening and hopeful.
I recommend all three, but especially the third one.
