Lignocellulosic Biochar – a Sustainable Reducing Agent for Iron- and Steelmaking Wastes

Biochar is increasingly recognized as a sustainable alternative to fossil-based reductants such as coke and coal in metallurgical processes. This review examines biochar’s potential for reducing solid iron- and steelmaking wastes, with particular focus on its performance in pyrometallurgical applications such as the Waelz process and Rotary Hearth Furnace. This study consolidates experimental findings, theoretical insights, and practical …
