Biocarbon for Steelmaking: A Drop-In Replacement for Coal and Coke
Engineered biocarbon built for the blast furnace and EAF you’re already running, no capital investment required to start testing.
Steel runs on fossil carbon. It doesn’t have to.
Blast furnace operations depend on coke and PCI coal for reduction chemistry and thermal energy. Electric arc furnaces depend on injection and charge carbon for slag foaming and chemical energy. Biocarbon is biogenic carbon engineered to the same specs as both, sourced from sustainably harvested biomass instead of mined coal, and it’s one of the only decarbonization levers that works with the furnace you already have.
One Product. Four Points of Application.
Fixed carbon and chemistry engineered for each application, from fine PCI powder to densified pellets for injection, charge, and ladle addition.
PCI Carbon
Ground to a fine particle size, with fixed carbon and volatile chemistry tuned for consistent raceway combustion.
Blast Furnace
Injection Carbon
Densified pellets, 1/8″+, sized for EAF lance and supersonic injection systems.
EAF
Charge Carbon
1/8″, 1/4″ or larger, built for direct furnace charging.
EAF
Ladle Carbon
1/8″, 1/4″ or larger, added at the ladle stage for final chemistry control.
Blast Furnace & EAF Routes
Works With the Furnace You’re Already Running
Blast Furnace / BOF
PCI & Coke ReplacementServes as a partial or full substitute for PCI coal and coke, supporting the same reduction chemistry without new capital equipment.
Electric Arc Furnace
Injection & Charge CarbonReduces reliance on fossil anthracite while maintaining energy efficiency and slag-foaming performance, compatible with supersonic injection systems used in modern EAF operations.

Common Questions From Mills
Can biocarbon replace PCI coal in a blast furnace?
Yes. Our PCI Carbon is ground to serve as a partial or full substitute for the coal used in pulverized coal injection, matching the specs mills already spec for fossil PCI coal.
Can biocarbon replace coke in a blast furnace?
Yes, in part. Biocarbon can replace a meaningful percentage of coke as a charge material, with the exact substitution rate depending on your specific furnace and burden design.
Is biocarbon cost-competitive with coke and PCI coal?
Pricing depends on volume, location, and current fossil carbon costs. Reach out and we’ll walk through the numbers for your specific operation.
Can biocarbon replace injection or charge carbon in an EAF?
Yes. Biocarbon can reduce reliance on fossil anthracite in EAF operations as both an injection material and a charge material, while maintaining slag-foaming performance.
What sulfur content is required for EAF injection or charge carbon?
Mills typically want sulfur as low as possible to avoid contaminating the steel. Our injection, charge, and ladle carbon products all come in under 0.05% sulfur.
Can biocarbon be injected into an EAF at supersonic speeds?
Yes. Lab work conducted with Linde has confirmed biocarbon can be delivered through next-generation supersonic high-momentum injectors used in EAF operations. See the full technical paper above.
