| Abstract: | "This paper presents the raw material composition and VOC treatment status of the packaging and printing industry in Zhejiang Province based on the survey data obtained in 2015 of 254 packaging and printing enterprises. To analyze the emission characteristics and calculate the emission coefficients of the packaging and printing industry, 100 typical enterprises were further screened according to different printing processes. The results showed that about two-thirds of packaging and printing enterprises failed to effectively dispose of VOCs; meanwhile, solvent-based materials were still commonly used in the packaging and printing industry. The main emission pollution factors of VOCs in the packaging and printing industry were ethyl acetate, isopropanol, ethanol, propyl acetate, and n-butyl acetate. The VOC emission coefficient of the packaging and printing industry in Zhejiang Province was 0.485 kg.kg(-1), of which the gravure printing was the primary source with VOCs emission coefficient of 0.634 kg.kg(-1). Compared with the material balance method, the error value from the emission coefficient method was less than 15%" |
