[Stoves] Biochar in the loo

[Stephen Joseph]

HI Josh

You actually don’t need a special toilet.  Just adding biochar to a pit latrine if the biochar is made from a grass/straw with a little lime and clay added to the feedstock  at around 450C has worked well in Vietnam

In a few days and in the coming weeks, i will be involved in disaster rehabilitation efforts, one after the Typhoon Haiyan and another in anticipation of the eruption of Mayon Volcano in the province of Albay. I will introduce char making stoves and bio char and then water filters and then thought about introducing terra preta toilets.

> The idea of using biochar in public toilets as a deodorizer is a good one. My own personal experience with biochar in dry toilets says it works and the deodorizing power is greatly enhanced by the addition of bokashi. It grows a lovely white mold over everyhing and it smells kind of like pickles.
