The Electric Arc Furnace (EAF) revolutionized steel production, making it the most recycled metal globally. It's a key player in reducing emissions and boosting circular economy benefits.
EAFD, produced at 1–3% of steel output, has long been a concern due to its chemical content. Past options like landfill were costly and offered no return.
EAFD contains 15–30% zinc, much of it from galvanized scrap. The Waelz Process transforms this waste into Waelz Zinc Oxide (WOx), a valuable industrial input.
A 50+ meter rotary kiln treats the dust under controlled conditions. Zinc vapors are collected, while iron remains inert—creating WOx ready for reuse in steel, ceramics, rubber, paint, and more.
Cutting-Edge Process & Automation
Our plants operate with continuous, high-performance systems designed to recover zinc with efficiency rates above 70%, using both pyrometallurgical and hydrometallurgical processes.
Advanced flue gas treatment ensures compliance with strict environmental regulations. Automation, IoT, SCADA, and smart sensors boost productivity while maintaining sustainability and safety standards.
