摘　　要：有色金属冶炼行业碳排放量大,降碳减排压力重,其中铅冶炼行业尤为突出。目前,我国1/2的铅产品源自含铅废料的再生利用,是二氧化碳排放的重要来源之一。为了解湖南省含铅废渣再生利用行业的降碳减排现状,以湖南典型含铅废渣再生利用企业为研究对象,参考行业温室气体排放核算方法与报告指南,核算了该企业2023年不同来源和不同工序的二氧化碳排放量。结果表明,该企业二氧化碳排放量占比最大的是能源作为原材料用途的排放,其次为净购入电力产生的排放。同时,对3家含铅废渣再生利用企业的二氧化碳排放因子进行了比较,表明使用清洁能源、开展余热回收、推广应用先进冶炼工艺可大幅降低二氧化碳排放量,是从源头提升含铅废渣再生利用企业降碳减排成效的有效手段。建议含铅废渣再生利用行业加快清洁能源、先进技术的普及与推广,推动行业的迭代与升级。Non-ferrous metal smelting industry has large carbon emissions and heavy pressure to reduce carbon emission,among which lead smelting industry is particularly prominent.Currently in China,half of lead products are from the recycling of lead-containing waste,which is one of the dominant sources of carbon emission.To understand the current situation of carbon emission reduction in the lead-containing waste recycling industry in Hunan Province,we selected a lead-containing waste recycling enterprise as the research object and calculated its carbon dioxide emissions from different sources and processes in 2023 with references to the accounting methods and reports guidelines of greenhouse gas emissions for the industry.The results showed that the largest proportion of carbon emission in this enterprise was the emission of energy used as raw materials,followed by the emission of net electric power purchase.Meanwhile,we compared the carbon dioxide emission factors of three lead-containing waste recycling enterprises.It was shown that the use of clean energy,the development of waste heat recovery,and the promotion and application of advanced smelting technology could significantly reduce carbon dioxide emissions,which were effective ways to improve the carbon emission reduction effect of lead-containing waste recycling enterprises from the source.Finally,we suggested that the lead-containing waste recycling industry should accelerate the popularization and promotion of clean energy and advanced technology,and promote the industry iteration and upgrading.
