再生金属行业具有节约资源、节约能源和保护环境的独特优势,是实现碳达峰碳中和的重要产业,再生金属冶炼企业是碳排放的重点单元,但再生金属(铝、铅、锌、锂)冶炼低碳企业评价标准目前仍是空白。为了更好地支撑再生金属(铝、铅、锌、锂)冶炼行业“双碳”工作,综合国家相关权威机构制定的低碳评价指导办法与评价指标,从实际情况出发,通过文献调研、专家咨询以及指标选取原则确定了适用于我国再生金属(铝、铅、锌、锂)冶炼低碳企业的评价指标。指标体系采用三级架构设计,各指标相互联系、相对独立、互相补充,包含2个一级指标(准则层)、6个二级指标(子准则层)以及17个三级指标(方案层)。通过专家评审和层次分析法确定低碳企业基本要求以及指标体系25个评价指标权重并进行一致性检验。根据权重对各个指标进行赋分,同时制定低碳企业综合评价细则及相关标准,综合得分[0, 60)的为非低碳企业,[60,70)为合格低碳企业,[70, 85)为良好低碳企业,[85,100]为优秀低碳企业。通过上述工作,最终建立我国再生金属(铝、铅、锌、锂)冶炼低碳企业评价指标体系,将有力支持再生铝、再生锌、再生铅、再生锂等类型企业通过采取源头减量、过程控制、末端治理的全过程、全链条、全生命周期环境风险管控措施,进一步促进相关企业应用低碳技术、实施低碳改造、优化能源资源配置、履行社会责任。
Abstract:The recycled metals industry has unique advantages in resource conservation, energy saving, and environmental protection, and it plays a crucial role in achieving carbon peak and carbon neutrality goals. Recycled metal smelting enterprises, particularly those processing aluminum, lead, zinc and lithium, are identified as key carbon-emission units. However, evaluation standards for low-carbon recycled metal smelting enterprises in these sectors have not yet been established. In order to better support the "dual carbon" goals of the recycled metal(aluminum, lead, zinc, lithium) smelting industry, based on the low-carbon evaluation guidance methods and evaluation indicators formulated by relevant authoritative national institutions, and starting from the actual situation, the evaluation indicators applicable to low-carbon enterprises in China's recycled metal(aluminum, lead, zinc, lithium) smelting industry were determined through literature research, expert consultation, and indicator selection principles. The indicator system adopts a three-level architecture design. Each indicator is interrelated, relatively independent, and complementary to each other. It includues 2 first level indicators(criterion layer), 6 second level indicators(sub-criterion layer), and 17 third level indicators(scheme layer). The basic requirements of low-carbon enterprises and the weights of 25 evaluation indicators in the indicator system are determined through expert review and Analytic Hierarchy Process(AHP), and consistency tests are conducted. Each indicator is scored by weight, and the detailed rules and relevant standards for the comprehensive evaluation of low-carbon enterprises are formulated. Enterprises with a comprehensive score of [0, 60) are non-low-carbon enterprises, [60, 70) are qualified low-carbon enterprises, [70, 85) are good low-carbon enterprises, and [85,100] are excellent low-carbon enterprises. Through this research, an evaluation index system for low-carbon enterprises in the smelting of recycled metals(aluminum, lead, zinc and lithium) in China will be ultimately established. This system will expected to strongly support enterprises of types such as recycled aluminum, zinc, lead and lithium to adopt environmental risk control measures covering the entire process, entire chain, and full life-cycle, including source reduction, process control, and end-ofpipe treatment. It also aims to promote the relevant enterprises to apply low-carbon technologies, implement lowcarbon renovations, optimize the allocation of energy resources, and fulfill their social responsibilities.
