RECYRON®: Idea to Innovation to Technology in Zero-Waste IronmakingRECYRON®: Idee, Innovation und Technologie für die abfallfreie Eisenherstellung

Waste products are actually raw materials in disguise, waiting for a smart person to identify them and put them back into use by an appropriate process. RECYRON® is a novel technology for a zero-waste ironmaking process. This process is designed to recycle all possible raw material wastes (RMWs) from an integrated steel plant to produce direct reduced iron (DRI). RECYRON® takes care all RMWs of steel plants and iron ore mines, starting from superfine ores, coke breeze, sinter dust and BF dust and sludge, mill scale, just to name a few. RECYRON® uses a simple technology like briquetting to its utmost potential to agglomerate all the wastes, and thereafter reduces it by using a rotary kiln. The reduced briquettes with high metallic iron could be used in mini-mills having electric arc furnaces (EAF), or to charge in the blast furnace to lower the coke rate as much as possible. The process is also able to generate power as the by-product. RECYRON® offers several advantages in parallel, such as reduction of landfill, complete utilization of raw materials, low CO2 footprint, and last but not the least, a highly profitable process. The financial aspects such as estimated CAPEX and OPEX along with the NPV (Net Project Value) and IRR (Internal Rate of Return) for plants are also discussed in this article.
