Recently, the "2019 China Printing Industry Innovation Conference" hosted by the State Press and Publication Administration was held in Beijing with the theme "Focus on Greening".

The reporter learned from the conference that in the past 70 years, China's printing industry has grown from more than 1,000 enterprises and less than 100,000 practitioners in the early days of the founding of New China to 98,000 enterprises and 2.704 million employees at the end of 2018, achieving 12,700. 100 million yuan printing total output value, total assets reached 1.52 trillion yuan. Among the 43 categories of culture and related industries, the revenue of printing enterprises above the designated size has accounted for 7.2% of the revenue of the enterprises above the designated size in the cultural and related industries.

"The printing industry has become a pillar industry in China's cultural industry, and has played a very important role in position building, technical support, serving the people, and inheriting civilization." Liang Yanshun, vice minister of the Central Propaganda Department, said at the meeting.

With regard to the green development of the printing industry, Liu Bingjiang, director of the Department of Atmospheric Environment of the Ministry of Ecology and Environment, introduced that in recent years, the Ministry of Ecology and Environment has closely cooperated with the State Administration of Press and Publication to actively carry out green printing work, sign the Strategic Cooperation Agreement for the Implementation of Green Printing and release The "Announcement on the Implementation of Green Printing" has formulated and revised many environmental labels and standards such as lithography and gravure printing.

Liu Bingjiang introduced that green printing has been fully covered in primary and middle school textbooks for the fourth consecutive year, and green printing is also actively promoted in the fields of bills, tickets, and food and drug packaging. More than 1100 enterprises have passed the green printing certification, and a large number of environmentally friendly raw and auxiliary materials, production processes and pollution prevention equipment have been widely used. Guangdong, Beijing, Shanghai, Chongqing, Shandong and other places have successively issued pollutant discharge standards for the printing industry to improve the environmental protection level of the printing industry.

"The green development of the printing industry has made some achievements. But at the same time, we must also see that there are still some problems in the ecological protection of the printing industry." Liu Bingjiang introduced that the volatile organic compounds (VOCs) pollution problem in the printing industry is still prominent The total emissions of VOCs in the printing industry nationwide exceeds 1.1 million tons, accounting for about 10% of industrial emissions, of which packaging and printing industry emissions account for 80% of the entire printing industry. Of the 98,000 printing companies nationwide, only more than 1,100 can get green certification, which is a little over 1%.

He Kebin, academician of the Chinese Academy of Engineering and dean of the School of Environment of Tsinghua University, introduced in the conference speech that from 1990 to 2017, the proportion of non-methane volatile organic compounds (NMVOC) emissions from solvent use sources in China's packaging and printing industry remained between 8% and 13%. between. The packaging and printing industry's contribution to the emissions of 1,3,5-triethylbenzene and 2-propanol is as high as 37.9% and 39.7%, respectively, which in turn contributes to the generation of ozone and secondary organic aerosols.

He Kebin introduced that in the "defense of the blue sky", the pain points of ozone and secondary organic particulate matter focus on VOCs. The pain point of VOCs reduction is solvent, and the printing industry is an important user of solvents.

"In the process of green development of the printing industry, there is still a lot of potential that can be tapped, and it can make a more important contribution to the future" blue sky defense war. "He Kebin said.
