Our group has pioneered game-changing technology to couple the giga-scale challenge of organic landfill diversion with the giga-scale opportunity of desert agriculture and greening. We are producing engineered biochar (EnB) by pyrolyzing organic waste, such as chicken manure, crop residue, and food scraps, and subjecting it to a post-treatment. We are studying the effects of its application on food crops as well as native plants as a function of synthesis, post-treatment, dosing, nutrient loading, and variable irrigation regimes.
