Helix Carbon says it can make iron cheaper by recycling blast furnace pollution | TechCrunch
The steel industry is a big polluter, but Helix Carbon can upcycle pollution from blast furnaces to drive down emissions and improve margins.
Graphite Electrodes: The Six-Month Carbon Behind Electric Steel and Lithium Batteries
Electric furnaces make 30% of the world's steel, 46% of the EU's and 71% of the US's, every tonne burns through a graphite column that takes half a year to produce, and battery anodes are made from the same coke in the same furnaces.

The Eerie Story of Low Background Steel
Bandits are plundering metal from old shipwrecks, in search, it seems for the world's rarest, and strangest, metal.
Frontier | Winston (@frontiermap)
The steel almost nobody can make. Grain-oriented electrical steel, or GOES, is the material at the heart of every large transformer core. It is a silicon-iron alloy at roughly 3% silicon, rolled into sheets 0.18 to 0.35 millimeters thick, with the crystalline grains forced into…
Turbine Tuesday: Forging
The lost art and Turbine economics
The US imports 82% of its large power transformers. How it got there, and what it will take to rebuild the capability.
Why the rebuild depends on metallurgy, apprenticeship, and one mill in Pennsylvania.
Can Wood Replace Steel? Chemically Modified Superwood Makes a Bold Case
InventWood just cracked the code on something that sounds like science fiction. They've figured out how to make wood stronger than steel by restructuring it at the molecular level. This isn't your typical engineered lumber story. We're talking about a material that delivers 50%…
