| 中文摘要: |
| 旨在推动餐饮用油行业的低碳转型，通过构建餐饮用油全生命周期评价方法，系统分析了原料供给、加工榨油、烹饪废弃及回收资源化4个阶段的碳排放特征与减排潜力。结果显示，2022年我国餐饮用油行业餐饮废油年产量约800万t，全生命周期碳排放量达9 242.9万tCO2eq，碳中和率为51.4%。其中，原料供给和回收资源化是关键减排环节。原料供给阶段可通过优化种植模式、提高出油率等方式降低碳排放，若我国油脂自给率持续提升，有望进一步提升系统碳中和率；若将居民食用油摄入量调整至膳食推荐水平，食用油总需求可降低约40%，相应减少系统排放量约2 907.1万tCO2eq；若推广新型废油回收装置，使废油回收率从25%提升至80%，结合生物柴油转化工艺，每年可实现减排量达1 829.3万tCO2eq，在此基础上如通过技术应用将回收率提高至97%，减排量可再增加213%，系统碳中和率有望提升至68.4%。综上，我国餐饮用油行业的碳减排潜力较大。 |

| To promote the low-carbon transformation of the catering oil industry, a life cycle assessment method was developed for cooking oil used in the catering section, and the carbon emission characteristics and reduction potential were systematically analyzed across four stages: raw material supply, oil processing, cooking and disposal, and recycling and resource utilization. The results showed that in 2022, the annual production of waste cooking oil in China′s catering oil industry was 8 million tonnes, with life cycle carbon emissions reaching 92.429 million tCO2eq and a carbon neutrality rate of 51.4%. Among these stages, raw material supply, and recycling and resource utilization were identified as key links for emission reduction. During the raw material supply stage, carbon emissions could be lowered by optimizing planting practices and improving oil extraction efficiency. If China′s self-sufficiency rate for oils continued to increase, the system′s carbon neutrality rate was expected to further improve. If residents′ edible oil intake was adjusted to the recommended dietary level, total edible oil demand could be reduced by about 40%, correspondingly to a reduction in system emissions of about 29.071 million tCO2eq. If new waste oil recovery devices were promoted to increase the recovery rate from 25% to 80%, and combined with biodiesel conversion technology, an annual emission reduction of 18.293 million tCO2eq could be achieved. On this basis, if the recovery rate was further increased to 97% through technological application, the emission reduction could be increased by an additional 21.3%, and the system′s carbon neutrality rate could reach 68.4%. In conclusion, the catering oil industry in China possesses substantial potential for carbon emission reduction. |
