Working with rice straw, I've really liked the result of "hammering". The idea is to break all the feedstock into small fibers, say, 15mm in length and 0.5mm in dia. Makes a great fibrous additive for adobe, plaster, etc., and i suspect would get the surface area up to a nice level for most chemical processes. I do it by hand, but a modified hammer mill could probly do it as well or better. Pretty sustainable.... -K ------------------------ Yahoo! Groups Sponsor --------------------~--> Yahoo!
