I don’t know what your threshold for “proven” is, but we are currently doing a pilot project with a college to use local biomass, make biochar, and heat a large campus building. The biochar yield is in the 25% - 32% range by mass of relatively dry biomass.</div><div class=""><br class=""><div class="">
