来自表 4-17 D01 钢厂生产吨材环境负荷编目表 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.
