Last but not least, a toilet that's cheap and easy. Waste goes into a compost pile. It's all in the book or I have a trimmed down MS Word copy. If anyone wants me to send, just email me. The book is thorough and the website weblife.org may still have
all the info, the whole book, online. read it all then trim it down to the most essential info.
This is the lowest cost, most usable one I have ever found. Every other composting toilet has a lot of drawbacks such as smell, size, work and high cost. In the US it will cost less than $25. You need only a few 5 Gal paint type buckets, a toilet seat and a pile of wood shavings or sawdust. The wasdust will help the waste compost. The author has had the resulting compost tested several times and it's quite safe. No nasty organisms, even in winter.
