1. A biocarbon pellet composition, wherein the biocarbon pellet comprises a fixed carbon content of at least 60 wt % and wherein the biocarbon pellet requires at least 240 minutes to reach 99% carbon oxidation, as determined by thermogravimetric analysis and recorded to a thermogravimetric analysis graph of weight loss versus time from a thermogravimetric analysis that measures the oxygen reactivity of the biocarbon pellet, wherein the thermogravimetric analysis is performed using a 40° C./min temperature ramp from 25° C. to 950° C. in the presence of pure oxygen.
