摘要

摘要: 酒糟作为酿酒工业产量最大的典型有机固体废弃物，其高效、低碳资源化利用是推动酿酒行业绿色转型、实现“双碳”目标的关键抓手，对行业可持续发展具有重要现实意义。研究以酒糟制备生物炭与有机肥2种主流资源化路径为研究对象，采用生命周期评价（LCA）方法，以各工艺环节已有文献公开数据为基础，系统核算了2种路径全生命周期内的CO₂排放量及碳减排效益，并从原料供应、设备投入、运行消耗等维度构建技术经济性评价模型，综合评估2种路径的成本、收益及投资可行性。结果显示：理论上1 t酒糟热解制备生物炭路径全流程总CO₂排放量为250.02 kg，碳封存减排量达120.29 kg，其具有低碳排放、固碳持久的核心优势；1 t酒糟发酵制备有机肥路径全流程总CO₂排放量为536.14 kg，碳减排量为86.22 kg，减排效果低于生物炭路径。技术经济性分析表明，酒糟生物炭单位净利润为471.97元/t，酒糟有机肥单位净利润为822.27元/t，相比之下，有机肥工艺的盈利水平更具优势。2种资源化路径均能实现CO₂减排，其中生物炭工艺侧重低碳环保，有机肥工艺在经济效益上表现更好。研究可为酿酒行业有机固废资源化路线选择、低碳技术推广及循环经济模式构建提供数据支撑。

Abstract: Distillers’ grains are a predominant type of organic solid waste with the largest output in the brewing industry. Their efficient and low-carbon resource utilization serves as a core approach to advance the green transformation of the brewing sector and achieve the Dual Carbon Goals. This study took two mainstream resource utilization routes of distillers’ grains， namely biochar preparation and organic fertilizer production， as the research objects. Based on publicly available parameters of each process unit in existing literature， the life cycle assessment （LCA） method was adopted to systematically calculate the carbon dioxide emissions and carbon reduction benefits of the two approaches throughout their full life cycles. Meanwhile， a techno-economic evaluation model was established from the perspectives of raw material supply， equipment investment and operational consumption， so as to comprehensively evaluate the cost， economic benefit and investment feasibility of the two processes. The results showed that theoretically， the total life-cycle CO₂emission of biochar production via pyrolysis of 1 t of distillers’ grains was 250.02 kg， with a carbon sequestration reduction of 120.29 kg， presenting distinct advantages of low carbon emission and long-term carbon fixation. By contrast， the total CO₂emission of organic fertilizer produced by 1 t of distillers’ grains fermentation reached 536.14 kg with a carbon emission reduction of 86.22 kg， whose carbon mitigation performance was inferior to the biochar pathway. Techno-economic analysis indicated that the net profit of distillers’ grain-derived biochar was 471.97 yuan per ton， while that of distillers’ grain organic fertilizer was 822.27 yuan per ton， demonstrating that the organic fertilizer production process delivers superior economic profitability. In conclusion， both resource utilization processes can effectively reduce carbon dioxide emissions. The biochar preparation process features low carbon output and environmental sustainability， whereas the organic fertilizer production process delivers superior economic benefits. This study can provide solid theoretical references and reliable data support for the selection of organic solid waste recycling strategies， the promotion of low-carbon technologies， and the establishment of circular economy models in brewing industry.
