[Stoves] [biochar] Re: research on activated carbon for water filters for the victims of disasters

Sat Jan 21 10:36:39 CST 2012

First time on the listserve, ya¹ll.  I do the newsletter of the U.S. Biochar
Initiative.  In the December 2011 edition there was a drinking water biochar
purification study from the University of Colorado.  There¹s a diagram of
the system on a poster we linked to.  Next, below, is a link to the Dec.
2011 edition in the archive, followed by a link to the poster.
