Reducing agent
A biogenic reducing agent replacing coke in the reduction of metal oxides and in blast furnace processes.
BioBriquette manufacturer · Mełno / Port of Gdańsk
BioBriquettes.
Carbon‑negative coke substitute for industry.
We produce biochar briquettes with repeatable, stable parameters. They reduce CO₂ emissions and the cost of carbon charges without changes to plant technology. Our own production in Mełno and a terminal at the Port of Gdańsk ensure continuity of supply.

01About us
Industry, metallurgy and logistics in one group
Biotech AG is a Polish industrial company specializing in the production of high-quality BioBriquettes, a modern alternative to fossil fuels in metallurgy and thermal energy.
We operate at the intersection of industry, metallurgy and logistics. We deliver solutions tailored both to large industrial plants and to individual customers. Our production plant was established on the site of a former sugar factory in Mełno near Grudziądz, fully adapted to modern industrial production.
“We turn waste biomass into industrial value, for cleaner green steel production.”

02Market context
Metallurgy decarbonization is already underway
CBAM, ETS and Fit‑for‑55 are genuinely changing the cost equation for every steel mill. A biochar reducing agent is today one of the fastest ways to lower those costs, without rebuilding the installation.
up to 100%
elimination of CO₂ emissions attributed to the reducing agent. Biogenic carbon according to the IPCC methodology.
Additional potentialRevenue from the sale of carbon removal credits for CO₂ permanently removed from circulation.
Technology proven in industry:
SSAB Oxelösund, Sweden
up to 55% of coke replaced with BioBriquettes with stable furnace operation, a reduction of 33–40 kg CO₂ per tonne of pig iron
ArcelorMittal Monlevade, Brazil
successful injection of torrefied biochar into the blast furnace, full compatibility with existing infrastructure
Swerim projects, Finland and Sweden
pilot and modeling studies confirming the technical feasibility of integrating biochar with metallurgical processes
Examples of market deployments of biochar technology in metallurgy.

Formats for different furnaces
80 × 60 × 40 mm±0,5%
60 × 40 × 28 mm±0,5%
The feedstock particle size remains constant. Only the briquette dimensions change, matched to different furnace types.
Renewable feedstock
Waste plant biomass: coconut shells, palm kernels, eucalyptus. The origin of the feedstock is documented and traceable for audit purposes.
Flexible production
We adjust the BioBriquette parameters to the individual requirements of industrial customers: blend composition, particle size, delivery form.
Feedstock from certified, sustainable sources
The SURE (Sustainable Resources Verification Scheme) certificate confirms compliance of the biomass with EU sustainability criteria (RED II). The origin of the feedstock is fully documented and traceable.
04Applications
One product, many applications
BioBriquettes are a versatile, renewable carbon charge for metallurgy. In a single product, they replace coke and fossil coal across many processes at once, without rebuilding the installation.
Recarburizer
Raises and adjusts the carbon content in steel and cast iron (recarburizing).
Slag foaming agent
Foams the slag in arc furnaces: greater energy efficiency and furnace protection.
Heat source
A renewable carrier of energy and heat in high-temperature processes.
Electric (arc furnace) steel (EAF)
A complete carbon charge for steel production in electric arc furnaces.
- stable combustion process and predictable charge parameters
- high energy efficiency of the process
- reduced CO₂ emissions and exposure to ETS and CBAM
- fewer fluxes and limestone thanks to low ash and sulfur content
- strengthening of ESG indicators and a “green steel” position
05Production
From biomass to briquette in a single plant
A modern Biotech Technologies line with a nominal capacity of 100 tonnes per hour, designed specifically for metallurgical biochar briquettes. A fully automated control system, continuous operation on two shifts, 18 experienced operators and engineers.
