| 中文摘要 |
| 印刷业一直是中国工业源挥发性有机物（VOCs）排放和管控的重点行业.然而，由于原料和工艺的复杂性和多样性，印刷业VOCs精细化排放清单及其减排潜力尚未被很好表征.考虑印刷业以往被忽视的半/中等挥发性有机化合物（S/IVOCs）排放，对现有VOCs排放系数进行改进，建立了2011~2020年中国印刷业VOCs精细化排放清单.并以2020年为基准年，通过情景分析法，预测了2030年不同情景VOCs排放量并分析其减排潜力.结果表明，2011~2020年中国印刷业VOCs排放量呈现先稳增长和下降的趋势，2020年相对2011年增加了29.6%，年均增长率为3.0%，主要与日益增长的印刷业市场消费需求和缺乏有效的行业VOCs综合治理措施有关.2020年中国印刷业VOCs排放量为86.1万t，凹版印刷和包装复合是贡献最大的两大工艺，占比分别为52.0%和28.7%.广东、江苏和浙江是VOCs排放贡献最大的省份，三省合计占比44.12%，是中国印刷业VOCs管控的重点地区.2030年印刷业基准情景、一般控制情景和严格控制情景VOCs排放量分别为118.7、68.4和36.2万t，相对2020年分别增长了37.9%、下降了20.6%和57.9%.凹版印刷和包装复合仍然是未来减排的重点. |
| 英文摘要 |
| 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. |
