MetPeel

Company Description

More than 99 percent of the world’s steel is rolled after casting. This process requires repeated fossil-fired heating and cooling of the material as it passes through multiple rollers. This is estimated to produce 0.2 to 0.4 tons of CO₂ per ton of steel product produced — 1 percent of all greenhouse gas emissions.

MetPeel replaces the fossil-fired, hot-rolling process with a new, low-temperature, single-step mechanical process for making steel sheet and strip that significantly reduces energy consumption and CO₂ emissions.

Fundamental improvements in materials science and control systems have enabled this process, which involves machining or “peeling” a continuous, thin metal strip directly from a solid metal feedstock surface in one single step without the need for external heating. MetPeel’s one-step process has the potential to eliminate 1.4 billion tons of CO₂ emissions annually by 2050.
