To explore the pollution characteristics and emission coefficient of volatile organic compounds (VOCs) released from the shoe-making industry in Zhejiang province, this paper used the survey data of 490 shoe enterprises obtained in 2015 to analyze the current VOCs treatment status of shoe-making industry, and further screened 178 key enterprises to study the emission coefficient of shoe-making industry. The results showed that more than 95% of shoe enterprises failed to effectively dispose VOCs, because most shoe enterprises did not have treatment facilities. Moreover, solvent-based materials such as adhesive and primer were still commonly used in approximately 90% of shoe-making industry. Meanwhile, the main pollutants of VOCs in shoe-making industry were 2-butanone, toluene, acetone, cyclohexanone, ethyl acetate, xylene, dichloromethane and cyclohexane. Furthermore, the VOCs emission coefficient of shoe-making industry in Zhejiang was 29.5 g, while it was affected by the production processes, and the cemented construction techniques was higher than the injection techniques, which VOCs emission coefficients were 35.9 g and 23.8 g, respectively. Furthermore, the major polluting stage of shoe-making industry was sole attaching, in which VOCs emission coefficient could reach 20.8 g.
