钢铁企业以其资源和能源密集、生产规模和物流量大、工序流程长等特点而产生大量固体废弃物,成为公认的污染大户。“十五”期间,我国钢铁产量高速增长,环境问题更为突出。如何提高资源和能源的使用效率,减轻环境负荷,走循环经济的道路,实现可持续发展,已成为未来我国钢铁行业发展的必然方向。
Iron and steel enterprises have become a recognized polluter with a large amount of solid waste due to their characteristics of intensive resources and energy, large scale of production, large volume of logistics and long process flow.
