The printing industry has always been the key source of volatile organic compound(VOC) emissions in China. However, owing to the complexity of raw materials and processes, the fine emission inventory and its future emission reduction potential of VOCs from the printing industry have not been well characterized. In this study, the existing VOCs emission factors of the printing industry were improved, considering the neglected semi/intermediate VOCs(S/IVOCs). An emissions inventory of VOCs from the printing industry in the period of 2011-2020 in China was compiled. Through scenario analysis, the emission of VOCs under different scenarios in 2030 was predicted, and the emission reduction potential was analyzed. VOCs emissions from the printing industry in China increased first and then decreased in the period of 2011-2020. Compared with that in 2011, VOCs emissions increased by 29.6% in 2020, with an average annual growth rate of 3.0%. This was mainly due to the increasing consumption demand in the printing industry market and the lack of effective measures for integrated management of VOCs. The VOCs emission of the printing industry in China in 2020 was 861 Gg. Gravure printing and packaging processing were the two most important processes, accounting for 52.0% and 28.7%, respectively. Guangdong, Jiangsu, and Zhejiang were the largest contributors to VOC emissions, accounting for 44.12% of the total emissions. VOCs emissions of the printing industry in 2030 were 1187 Gg, 684 Gg, and 362 Gg for the baseline scenario, the general control scenario, and the strict control scenario, respectively. Compared to that in 2020, emissions under different control scenarios in 2030 increased by 37.9% and decreased by 20.6% and 57.9%, respectively. Gravure printing and packaging processing are still the focus of emission reduction.
在中国，印刷行业一直是挥发性有机化合物（VOC）排放的主要来源。然而，由于原材料和工艺的复杂性，印刷行业VOCs的精细排放清单及其未来减排潜力尚未得到很好的描述。在本研究中，考虑到被忽视的半挥发性/中间挥发性有机化合物（S/IVOCs），对印刷行业现有的VOCs排放因子进行了改进。编制了2011-2020年中国印刷行业VOCs排放清单。通过情景分析，预测了2030年不同情景下的VOCs排放量，并分析了减排潜力。2011-2020年期间，中国印刷行业的VOCs排放量先增加后减少。与2011年相比，2020年VOCs排放量增长了29.6%，年均增长率为3.0%。这主要是由于印刷行业市场消费需求的增加以及VOCs综合管理有效措施的缺乏。2020年中国印刷行业的VOCs排放量为861Gg。凹版印刷和包装加工是两个最重要的工艺，分别占52.0%和28.7%。广东、江苏和浙江是VOC排放的最大贡献地区，占总排放量的44.12%。2030年印刷行业的VOCs排放量，基准情景为1187Gg，一般控制情景为684Gg，严格控制情景为362Gg。与2020年相比，2030年不同控制情景下的排放量分别增加了37.9%、减少了20.6%和57.9%。凹版印刷和包装加工仍然是减排的重点。
