The Next Generation of Iron Production
Turning Waste Fines and Low-Grade Ore Into Steel-Ready Iron
Market Reality for Steel and Mining Producers
Scrap availability is tightening, and scrap quality is increasingly inconsistent. Demand for pig iron and HBI is rising, particularly for EAF steelmaking, as producers seek reliable, high-purity metallic inputs for high-quality steel production.
At the same time, steelmakers pay to remove fines and waste, then buy replacement iron at market prices. Mining fines and low‑grade ore are sold at significant discounts despite strong iron demand.
The Opportunity Hidden in Iron Waste
A disposal liability waiting to become a revenue-generating asset.
Across steel mills and mining operations, valuable iron-bearing materials such as fines, tailings, mill scale, dust, and low-grade ore are routinely discarded, stockpiled, or sold at significant discounts despite strong demand for dense, high-quality iron units. Alterna unlocks the value trapped in these underutilized materials and converts them into steel-ready iron products.
The result is a shift from material liability to revenue-generating product, with minimal capital required for the customer.
Before Alterna
Waste fines incur disposal costs
Valuable iron remains unused
Replacement iron must be purchased
With Alterna
Waste becomes feedstock
Pig Pucks are produced on-site
Valuable iron is returned to the operation
Pig Pucks
A New Class of Steel‑Ready Iron
Alterna’s Pig Pucks are a pig-iron-class, steel-ready iron product designed as a drop-in product for existing steelmaking processes — produced from waste fines and low‑grade materials.
