If there is to be a "biochar as a by-product and its application(s)" sub-topic at the conference then of course I will put in a plug for "use in household water treatment."
I wish that I could be there but I won't make it back to SE Asia this winter (will be there winter 2013/14). If there is sufficient interest in a biochar applications session and water treatment/water quality concerns, I could ask a colleague in Chiang Mai, Thailand to attend and present some of our work.
