In some variations, the invention provides a biocarbon composition comprising a low fixed carbon material with a fixed carbon concentration from 20 wt % to 55 wt %; a high fixed carbon material with a fixed carbon concentration from 50 wt % to 100 wt % (and higher than the fixed carbon concentration of the low fixed carbon material; from 0 to 30 wt % moisture; from 0 to 15 wt % ash; and from 0 to 20 wt % of one or more additives (such as a binder). Some variations provide a process for producing a biocarbon composition, the process comprising: pyrolyzing a first biomass-containing feedstock to generate a low fixed carbon material; separately pyrolyzing a second biomass-containing feedstock to generate a high fixed carbon material; blending the low fixed carbon material with the high fixed carbon material, thereby generating an intermediate material; optionally, blending one or more additives into the intermediate material; optionally, drying the intermediate material; and recovering a biocarbon composition containing the intermediate material or a thermally treated form thereof.

Some variations provide a carbon-negative carbon product that is characterized by a carbon intensity less than 0 kg COe per metric ton of the carbon-negative carbon product, wherein the carbon-negative carbon product contains at least about 50 wt % carbon. In some embodiments, the carbon intensity is less than −500 kg COe per metric ton of the carbon-negative carbon product. Other variations provide a carbon-negative metal product (e.g., a steel product) that is characterized by a carbon intensity less than 0 kg COe per metric ton of the carbon-negative metal product, wherein the metal product contains from 50 wt % to 100 wt % of one or more metals and optionally one or more alloying elements. In some embodiments, the carbon-negative metal product is characterized by a carbon intensity less than −200 kg COe per metric ton of the carbon-negative metal product. The carbon-negative metal product can contain a wide variety of metals.

Some variations provide a composition for reducing a metal ore, the composition comprising a carbon-metal ore particulate, wherein the carbon-metal ore particulate comprises at least about 0.1 wt % to at most about 50 wt % fixed carbon on a moisture-free and ash-free basis, and wherein the carbon is at least 50% renewable carbon as determined from a measurement of theC/C isotopic ratio. Some variations provide a process for reducing a metal ore, comprising: providing a biomass feedstock; pyrolyzing the feedstock to generate a biogenic reagent comprising carbon and a pyrolysis off-gas comprising hydrogen or carbon monoxide; obtaining a metal ore comprising a metal oxide; combining the carbon with the metal ore, to generate a carbon-metal ore particulate; optionally pelletizing the carbon-metal ore particulate; and utilizing the pyrolysis off-gas to chemically reduce the metal oxide to elemental metal, such as iron.

Bio-reduction of metal ores integrated with biomass pyrolysis

A method is provided for producing a biochar solution. The method comprises the steps of collecting biochar particles, dispersing the biochar particles in a liquid solution and adding a stabilizing agent to keep the biochar in flowable suspension. The stabilizing agent may be added to the liquid solution or to the biochar prior to placing the biochar in solution.

Biochar suspended solution

A method for using treated biochar to reduce the overall environmental impact of farming and minimize the carbon footprint of farms is provided. The method comprising engaging in one or more of the following practices: (1) combining treated biochar with feed or using biochar as feed for animals to reduce methane from enteric fermentation and increase animal health and nutrition; (2) combining treated biochar with compost, animal bedding or manure piles to reduce odor and increase nutrient retention; (3) applying treated biochar to lagoons to reduce odor and treat water; (4) applying treated biochar to pastures to increase pasture health; (5) applying treated biochar to crops to increase crop productivity, healthier roots and prevent fertilizer leaching; and (6) using the carbon negativity of a produced biochar to reduce the overall farm or ranch carbon footprint.
