Management Guidelines
Focus on managing air pollution at the source
- The Company regularly sprays wood vinegar and biological deodorizers on cup lump stacks to reduce odors caused by organic degradation of cup lump raw materials.

Utilize air pollution control systems and technologies
- The Company uses a Wet scrubber odor treatment system, a Deodorizer system, and a Bio-filter system to reduce odors from the rubber drying process and odors from the production of mixed rubber (Mixture). Currently, the Wet Scrubber system is being used in conjunction with the Bio-filter system in a total of 12 factories.
