I am fascinated by cob homes. The aesthetic, the sustainability, the construction and participation processes are immensely appealing. For the past several months I’ve had a dream of moving to the Pacific Northwest and building a cob house, and I’ve been trying to figure out what I will use as energy sources, water and septic systems, etc. I had been trying to find a good composting toilet solution and all the options I came across started at at least $1000 and weren’t overly compelling.
A few weeks ago I participated in helping a man named John Fox build his cob home, and this furthered my interest in green building. On John’s property there was obviously no real toilet (”the worst thing you can do with a clean bowl of water,” he advised us, “is to go to the bathroom in it. Our current oil crisis does not compare to our future water crisis.”) What he had instead was a 5 gallon bucket with a conventional toilet seat and lid on top. Next to this he had a pile of sawdust, which was used to cover up additions to the bucket and keep it from smelling. The bucket was eventually added to his active compost pile, which after 2 years would be usable for any composting purposes.
Last week I was visiting my family in California and we were wandering past Home Depot’s new “energy-efficient” products. I saw this display for green toilets that use up to 5,000 fewer gallons of water every year (which begs the question, how much DO they use?). Off to the side, for only $4.97, was probably the most efficient and water-saving solution of them all.
