In the second half of 2023, DSOC completed the renovation of the painting workshop and pretreatment line organic waste gas treatment facilities. Following the renovation, the painting workshop adopted the "zeolite rotary wheel concentration + CO catalytic oxidation" process, and the pretreatment line adopted the "cartridge dust removal + RTO regenerative combustion" process. The application of these processes achieved a leading level of treatment efficiency in the country and reduced the emissions of volatile organic compounds. This contribution is of great significance for controlling ozone pollution, reducing haze weather, and improving air quality.

Throughout this process, DSOC demonstrated a high sense of responsibility and mission towards environmental protection. By adopting advanced waste gas treatment technology, it improved its environmental performance and made a positive contribution to achieving sustainable development.
