摘要：

无水印刷技术作为印刷行业源头替代的重要技术之一,主要适用于出版物印刷、包装印刷等平板印刷,在国际上已得到了普遍应用。文中以北京某印刷企业为案例,开展企业层面引进无水印刷技术后挥发性有机物（VOCs）与CO₂协同减排评估,通过实地监测和公开文献获取数据,进行实证研究。结果表明,与基准情景相比,采用无水印刷技术和安装末端治理设施均能减少VOCs的排放量,但采用无水印刷技术的VOCs减排效果更佳,减排率为60%左右。采用无水印刷技术后CO₂排放量显著下降,安装末端治理设施会增加CO₂排放量。以无水印刷为代表的源头替代技术可以实现VOCs和CO₂的协同减排。

Abstract:

Waterless printing technology, as one of the important technologies to replace the source of printing industry, is mainly suitable for publication printing, packaging printing and other plate printing, and has been widely used in the world. Taking a printing enterprise in Beijing as an example, the co-benefit evaluation of Volatile Organic Compounds (VOCs) and CO₂ emission reduction after the introduction of waterless printing technology at the enterprise level was carried out, and the data were obtained through field monitoring and open literature to conduct empirical research. The results are as follows. (1) Compared with the baseline scenario, the implementation of waterless printing technology and the installation of terminal treatment facilities can both reduce VOCs emissions, but the implementation of waterless printing technology has better emission reduction effect, and the emission reduction rate is about 60%. (2) After the implementation of waterless printing technology, the CO₂ emission is significantly reduced, but the installation of terminal treatment facilities will increase the CO₂ emission. (3) The source substitution technology represented by waterless printing can realize the synergistic emission reduction of VOCs and CO₂.
