Use advice for data set | This dataset, reflecting the environmental burden of producing one ton of metallurgical ash based on the year 1998 data, should be used with caution. Due to potential changes in environmental regulations and manufacturing technologies, the actual current environmental impact may differ. Users should consider updating these values with current local data for precise life cycle assessments. Additionally, users should account for any potential changes in metallurgical process efficiencies and recycling practices that may affect the environmental profile of the material. |
Technical purpose of product or process | Metallurgical ash is used as an agent in several metallurgical processes including acting as a refractory material, flux in the steelmaking process, and for the adjustment of slag properties. It is also utilized in other industrial processes that require compounds high in calcium oxide. |
