Aluminium: the 20 largest CO2 emitters worldwide

The 20 largest aluminium-industry CO2 emitters worldwide — satellite-estimated. Smelting is ≈1.6 t CO2/t direct plus the power behind 13–15 MWh/t; every plant below is CBAM-relevant if it ships to Europe.

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)
