Biomass should never be just burnt, instead it should be fractionated to it's high value uses. Recent NATURE STUDY; Sustainable bio char to mitigate global climate change http://www.nature.com Not talked about in this otherwise comprehensive study are the climate and whole ecological implications of new , higher value, applications of chars. First, the in situ remediation of a vast variety of toxic agents in soils and sediments. Biochar Sorption of Contaminants; Dr. Lima's work; Specialized Characterization Methods for Biochar at the 2010 US Biochar Conferenceat ISU And at USDA; The Ultimate Trash To Treasure: *ARS Research Turns Poultry Waste into Toxin-grabbing Char Second, The uses as a feed ration for livestock to reduce GHG emissions and increase disease resistance. Third, Recent work by C. Steiner, at U of GA, showing a 52% reduction of NH3 loss when char is used as a composting accelerator. This will have profound value added consequences for the commercial composting industry by reduction of their GHG emissions and the sale of compost as a nitrogen fertilizer.
