Scrap/EAF route conversion

Melting recycled scrap in an EAF instead of reducing ore with coke — the proven structural decarbonization of steel, bounded only by scrap supply and grade needs.

How it works

Mechanism & sizing

0.4 vs 1.9 t CO2/t direct. Hybrid stepping stones: more scrap charge in the BOF, DRI feeding EAF (gas now, H2 later). Scrap markets are the constraint — which is why scrap is becoming a strategic commodity under CBAM.

Inzonex removable modular insulation on industrial equipment
Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

  • Up to 90% less heat loss from insulated surfaces
  • Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
  • 6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
  • Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
  • Typical payback under 2 years (some 9–11 months)

FAQ

Scrap/EAF route conversion, answered

Why is EAF so much cleaner?
No ore reduction: the carbon chemistry that defines the blast furnace simply isn't there — only melting energy remains.
Can all steel be EAF?
Grade limits from scrap residuals (copper) constrain some flat products; DRI-EAF covers most of the rest. Sword is scrap availability.
What's the CBAM effect?
Route choice is the single biggest lever on embedded emissions per tonne — EAF exporters hold a structural CBAM advantage.
