A method and system for converting waste using plasma into ammonia. The method uses minimal fossil fuel, and therefore produces a minimal carbon footprint when compared to conventional processes. The method includes the steps of supplying a biomass material to a plasma melter; supplying electrical energy to the plasma melter; supplying steam to the plasma melter; extracting a syngas from the plasma melter; extracting hydrogen from the syngas; and forming ammonia from the hydrogen produced in the step of extracting hydrogen.
