Comparison Before and After Implementation:

实施前后对比：

- Ecology: Before implementation, the greening of Ningbo Iron and Steel's factory area was mainly single protective belts and green hedges, with insufficient landscape and ecological properties, and part of the production wastewater was discharged; after implementation, the factory area has become a garden-style space with "flowers in all seasons and evergreen in all seasons", with zero wastewater discharge, annual carbon emissions from logistics and transportation greatly reduced, and the quality of the ecological environment significantly improved.

- 生态：实施前宁波钢铁厂区绿化以单一防护带、绿篱带为主，景观性与生态性不足，生产废水部分外排；实施后厂区成为 “四季有花、四季常绿” 的花园式空间，废水零排放，物流运输年碳排放大幅降低，生态环境质量显著提升。

- Resources: Before implementation, part of the metallurgical slag was treated by landfill, with low solid waste utilization rate and insufficient waste resource utilization; after implementation, the metallurgical slag is fully converted into usable products, with a comprehensive solid waste utilization rate of over 99%, and it was successfully selected as a Zhejiang "Waste-Free Factory" in 2022, with prominent resource recycling benefits.

- 资源：实施前冶金渣部分采用堆存处理，固废利用率较低，废弃物资源化程度不足；实施后冶金渣全量转化为可利用产品，固废综合利用率超 99%，2022 年成功入选浙江省 “无废工厂”，资源循环效益凸显。
