Electric Arc Furnace (EAF) Slag | US EPA

About EAF Slag. EAF slag is a rock-like material generated during the steel-making process. Approximately 130 facilities across the United States generate EAF slag. EAF slag is used as an alternative to rock fragments, both in encapsulated uses (e.g., contained in concrete) and unencapsulated uses (e.g., loose ground cover material).
