Dear Art and All I support your efforts in this regards and it would be good to have a webinar on the subject.
I remind all as does Richard S that one of the obvious uses of char and char fines (which I consider to be separate resources) is as fuel in another stove or other combustor. The many other uses are too long to list here. Cecil Cook is one of those who has attempted to quantify the total resource available at the various stages of the value chain from the standing tree to the cooked food over an urban fire. He has studied this in Mozambique with an emphasis on Maputo and in Lusaka, Zambia. The nature of the opportunity is of course geographically distributed. The char remaining in the hole in the ground on the farm may have a local value that makes it not worth transporting out of the region. The char dust underfoot in the city's markets is probably best used as fuel to reduce importation. The additional mass of material available at each transport or vending node is a substantial fraction of the total resource. The national and international marketing opportunities for these fractions would be a good subject for discussion.

As a person involved in one of the few biochar stove projects (Estufa Finca) buying charcoal from stove users in our program and reselling it as biochar, filtration media, as ingredients for cosmetics, etc.. I would like to join with the colleagues who have already spoken up and help you plan a webinaron the topic of these alternative uses for char. Thank you to Winrock for extending this offer. Please feel free to contact me directly. Art Donnelly >
