Basic ApproachBack to Top

The TOPPAN Group has formulated the following basic policies on chemical substance control.

We refrain from the use of hazardous chemical substances as a basic rule. We may, however, resort to the use of hazardous substances when their use is legally permitted and no alternate technologies are available. Even when these latter conditions apply, we properly control the substances and take steps to reduce their usage or replace them with substitutes.

Every chemical substance used within our business operations is monitored. We seek to eliminate obstacles to environmental conservation in advance by constantly improving the substance control methods we have voluntarily set as a business operator.

We strive to reduce the use of chemical substances in order to mitigate their impacts on the environment. By determining substances and applications for reduction on a priority basis, we have been reducing their use and replacing them with safer substitutes. A set of Standards for the Management of Chemical Components of Raw Materials has been established to govern the substances and materials we purchase. These standards list chemical substances whose usage is banned or restricted as raw materials in conformance with international and Japanese laws and regulations on chemicals. The list is regularly reviewed to assure chemical management, and every supplier is asked to control the substances listed.

Toppan Inc. has also listed particularly hazardous chemicals as “high-risk chemicals” sorted out from the chemical substances designated under the Pollutant Release and Transfer Register (PRTR) law of Japan. The Company prohibits the use of products that contain listed chemicals as a basic rule. This list is reviewed every year. Group production sites have been properly controlling chemical substances in parallel, according to their management procedures.

For VOC emissions into the atmosphere, adequate treatment is applied before release to ensure that the emission volumes and concentrations are controlled at proper levels. Increasing efforts are also made to reduce the use of VOCs.
