<div dir="ltr">Richard,<br><br>I assume that we are still taking about rice hulls. I supposed that this pile of rice hulls is being decomposed anaerobically. If this is the case, do you know how much methane is being released? You talk about a high silica content ending up in the ash. Have you checked the composition of this ash?<br>

Where it is left to decompose in huge multi acre 50 ft tall mounds, (eg Mbale Uganda), you observe a glutenous mass which can work very well even with other granular solids (sawdust, charcoal fines) right off the mound. Take it off the fields dry (in such as Bamaco Mali ) and it has to indeed be blended with softened fibrous material. In either condition (whether gluten or fiber bound) the high silica generates lots of ash. </div>
