Environmental Data
Industrial waste generation and landfill increased from fiscal 2014, but this is due to surplus earth from land work at the Zeon Corporation Tokuyama Plant (improvement of carbon nano-tube plant construction area, hydrant piping burial). We separated soil that could be reused to minimize the amount sent to landfill.

● Trafficking eradication campaign
The “trafficking eradication campaign” was held in October 2015 at Tokuyama Station
We have a deep relationship with customs, due to our involvement with customs clearance, and we actively participate in the campaign.
In order to heighten awareness of the illegal import and export of weapons, narcotics, and fake brand-name products, in addition to relevant agencies such as customs, coastguard and police officials, the character of customs, "custom-kun" and the Coast Guard character "umin" also participated by distributing leaflets about the prevention of smuggling, deepening the understanding of the general public. This year, Mr. Kajiyama, a registered customs specialist in the logistics division joined again as a member of the Moji customs registered customs specialist division.  
● Advertising publications, etc.

We advertise in the local Shunan City and Kudamatsu City public relations magazines, and placed adverts in programs at local sports and cultural events in order to inform as many local residents as possible that we do water quality examinations, demonstrating our environmental projects.
