Abstract: Systems and methods for a biochar retort kiln are disclosed herein. A method for making biochar includes placing waste bio mass in a cylindrical retort chamber. The retort chamber extends outwardly at a first end and a second end from a fire box. Pyrolysis is fueled by igniting the waste biomass. Syngasses are evacuated through one or more holes defined by the cylindrical retort chamber, such that the syngasses are driven out of the biomass and out of the retort chamber to be consumed by a fire in the firebox. The byproduct of the described method is biochar.
