February 11, 2025 – The rubber and plastic materials manufacturing industry inevitably generates oil fume emissions during its production processes, primarily stemming from kitchens, injection molding, and vulcanization procedures. To tackle this environmental challenge, the industry and external stakeholders have been exploring and adopting a series of innovative technologies, striving to ensure that emissions meet standards and mitigate their impact on the environment.
In injection molding and vulcanization processes, the issue of emissions is particularly prominent, containing harmful components such as particulates, non-methane volatile organic compounds (NMVOCs), and sulfides. In response, enterprises ingeniously utilize exhaust hoods to collect emissions, which are then treated through activated carbon adsorption systems or a combination of spray and activated carbon adsorption processes. The treated emissions are ultimately discharged through high-altitude exhaust stacks. Fuzhou Fuguang Rubber & Plastic and Zhejiang Junhe Rubber Technology are typical practitioners of this treatment method.
The industry has also spared no effort in exploring oil fume treatment technologies. Activated carbon adsorption technology is widely favored by enterprises for its efficient removal of organic compounds and odors. Both Fujian Fuguang Rubber & Plastic and Zhejiang Junhe Rubber Technology have adopted activated carbon adsorption devices, achieving remarkable results. Additionally, oil fume purifiers, as powerful tools for kitchen oil fume treatment, effectively remove particulates and harmful substances through physical filtration and electrostatic adsorption. Yangzhou Baoying County has even introduced high-voltage electrostatic industrial oil fume treatment equipment, which precisely adsorbs oil fume particles through a high-voltage electrostatic field, achieving efficient purification. Furthermore, the application of photocatalytic oxidation technology utilizes ultraviolet light and other light sources to decompose harmful substances in oil fumes into harmless ones, providing a new approach to emission treatment.
According to the Color Masterbatch Industry Network, the treatment of oil fume emissions in the rubber and plastic materials manufacturing industry must strictly adhere to relevant regulations such as the “Emission Standards for Oil Fume from Food Service Establishments” and the “Emission Standards for Pollutants from the Rubber Products Industry.” In practical operation, numerous enterprises, including Xiangshui Dongyuan Recycled Rubber and Shaanxi New Idea Rubber & Plastic Co., Ltd., have achieved emission concentrations of kitchen oil fumes far below the standard limits through meticulous treatment, demonstrating the industry’s proactive response and implementation of environmental regulations. Simultaneously, the removal efficiency of oil fume purification facilities has become a key indicator for measuring treatment effectiveness, with high-efficiency equipment achieving removal rates of over 95%.
In addition to continuous innovation in technology, the implementation of supplementary measures is also crucial. Enterprises ensure the long-term effective operation of oil fume purification facilities by regularly replacing filter materials, cleaning, and maintaining equipment. Moreover, enhancing workshop greening and ventilation further reduces the impact of emissions on the surrounding environment. Additionally, raising public awareness of oil fume pollution issues and encouraging enterprises to strengthen their environmental consciousness is also an important aspect of promoting green development in the industry.
Looking ahead, the rubber and plastic materials manufacturing industry will continue to adhere to the development direction of technological innovation, industrial promotion, and international cooperation in the treatment of oil fume emissions. We have reason to believe that with the continuous advancement of technology and the increasing maturity of the market, the treatment of oil fume emissions in the rubber and plastic manufacturing industry will embrace a broader development prospect.
