摘　　要：在“双碳”目标背景下,生态环境部会同国家15部委制定了《关于建立碳足迹管理体系的实施方案》,中药制药企业开展相关产品的碳足迹核算方法研究迫在眉睫。该研究基于生命周期评价理论,以某企业生产的桑叶提取物为例,分析中药提取物从“从摇篮到大门”的碳足迹。研究结果表明,每生产1 kg产品,原材料获取阶段、运输阶段及提取物生产阶段的碳排放分别为-20.569、1.205、173.577 kgCO_(2)eq(二氧化碳当量),产品最终碳足迹为154.213 kgCO_(2)eq·kg^(-1)。生产阶段碳排放量最高,其中,乙醇溶剂的消耗对碳足迹贡献最大,占比25.71%,超四分之一;其次是中药渣处理过程,占比19.67%;其后是废水处理、热蒸汽及饮用水的消耗,占比分别为17.71%、17.43%及16.90%;电力消耗和包装材料的使用碳排放量相对较小,仅为2.58%,特别是包装材料的消耗,仅0.04%,可忽略不计。研究结果有望为中药企业开展产品碳足迹研究提供方法参考,为中药全产业链减污降碳协同创新提供思路,发展基于绿色低碳制造的现代中药产业新质生产力。Under the background of carbon peaking and carbon neutrality goals,the Ministry of Ecology and Environment,together with 15 national ministries and commissions,has formulated the Implementation Plan on Establishing a Carbon Footprint Management System,and it is urgent for traditional Chinese medicine(TCM)pharmaceutical enterprises to carry out research on carbon footprint accounting methods of related products.Based on the life cycle assessment(LCA)theory,taking mulberry leaf extract produced by a certain enterprise as an example,this study analyzed the carbon footprint of TCM extracts during the life cycle.The results show that for every 1 kg of product produced,the carbon emissions from the stages of raw material acquisition,transportation,and extract production are-20.569,1.205,and 173.577 kgCO_(2)eq(CO_(2)equivalent),respectively.The carbon footprint of the product is 154.213 kgCO_(2)eq·kg^(-1).In addition,the carbon emission is the highest in the production stage,in which the consumption of ethanol solvents makes the greatest contribution to the carbon footprint,accounting for 25.71%,more than one-fourth of the total carbon footprint.The second contribution was from the treatment process of TCM residues,accounting for 19.67%,closely followed by wastewater treatment(17.71%),the consumption of hot steam(17.43%),and drinking water(16.90%).The consumption of electric power and packaging materials has a smaller carbon emission of 2.58%.In particular,the carbon emission caused by the consumption of packaging materials is only 0.04%,which is negligible.The results of the study are expected to provide a reference for TCM enterprises to carry out research on the carbon footprint of products,offer ideas for collaborative innovation in reducing pollution and carbon emissions throughout the entire industry chain of TCM,and develop new quality productivity of modern TCM industry based on green and low-carbon manufacturing.
