Three levers. One blast furnace.
The LeanCarb™ product line targets CO₂ reduction at existing blast furnaces — retrofitting hardware, not replacing the route.
01
Hot blast booster
Delivered with LuxPlasma
Air-plasma torch between cowpers and bustle pipe. Recovers lost hot-blast temperature on aging stoves, substitutes natural gas or coke-oven gas with renewable electricity.
- — Recovers nominal hot-blast temperature of aging stoves
- — +10 °C hot blast ≈ −1 kg coke per tHM
- — Scope 1 CO₂ cut at the stoves
02 AISTech 2026
Injection
Plasma + H₂-rich fuel at tuyeres
Smart combination of plasma power and hydrogen-rich auxiliary fuel injected at the tuyeres. Reversible retrofit that pushes the H₂-injection limits set by the BF heat balance.
- — Up to 20% CO₂ reduction — more than 300 kg/t vs. conventional PCI
- — Reversible, no major changes at the BF
- — Flexibility to use cheap renewable electricity when available
03 Under development
TGR
Top-Gas Recycling
Blast-furnace Top-Gas Recycling solution — capturing, cleaning and reinjecting top gas as reducing agent. R&D stage.
- — Closes the carbon loop at the furnace
- — Combines with plasma superheating
- — Under development
Decarbonation · LuxPlasma
The blast furnace is not yesterday's technology. It is the backbone of the transition.
Phoenix Technologies — a Pirson Group company — and Europlasma have formed LuxPlasma, a Luxembourg 50/50 joint venture to produce plasma torches (TAP) for the steel industry — modernising existing blast furnaces rather than swapping the technology.

Joint venture
Phoenix Technologies · Europlasma
How it works — TAPs inject very-high-temperature gas directly into the furnace, reducing coke-oven gas usage and, by cracking emitted CO₂, recycling it as a reducing agent. Early commercial interest is already reported across Europe and Brazil.
— Energy balance & top-gas recovery
— PCI optimisation & biomass injection
— BF / DRI / EAF route integration
From pre-feasibility to first tap.
Four phases, delivered as a single continuous engagement or as targeted interventions.
- 01
Initial assessment
Pre-feasibility, process review and technology selection for BF and BF–BOF routes.
- 02
Engineering
Basic and detailed engineering across refractory, hot-metal handling, gas cleaning, stoves.
- 03
Procurement & construction
Vendor selection, contracting, construction management and site coordination.
- 04
Execution support
On-site ramp-up, commissioning and performance verification through first campaign.
Four pillars of the BF–BOF route.
Not a matrix of services — four questions your production team asks, and how we answer them.
01
Expertise & experience
Seasoned engineers with decades of BF and BOF operations. Every challenge on the production route, we have seen before.
