Our factory prioritizes environmentally friendly production and has obtained ISO 14001 environmental management system certification. Our environmental management measures during production are as follows:
Waste Gas Treatment: Trace volatile gases generated during the nitrocellulose processing process are purified by a dual treatment system combining activated carbon adsorption and UV photolysis before discharge. Emission concentrations comply with the “Integrated Emission Standard for Air Pollutants” (GB 16297-1996).
Wastewater Treatment: Wastewater from equipment washes is treated at the factory’s sewage treatment station (using a “coagulation and sedimentation + biochemical treatment” process) to meet the Class III standard of the “Integrated Emission Standard for Wastewater” (GB 8978-1996). It is then sent to a municipal sewage treatment plant for advanced treatment.
Solid Waste Treatment: Production scraps (celluloid waste) are flammable solid waste and are professionally incinerated or recycled by qualified hazardous materials disposal companies. They are not discarded carelessly. Annual environmental inspection reports issued by the environmental protection department are available.
