Chemical Substances Management/Pollution Measures

Chemical Substances Management

For various types of chemical substances used in business activities, we have established a company-wide management system for proper control of these substances from the viewpoint of business continuity planning (BCP). For daily management, the Chemical Registration Information system (CRIS) developed by Shimadzu System Development Corporation is used. The system manages the quantities at purchase, use and disposal stages, allowing the aggregation of inventory and usage amounts, and easy preparation of reports based on the PRTR Law in Japan*.
Furthermore, not limited to the department directly handling chemical substances, we provide education also for sales departments about the importance of managing permits and approvals, communicating daily operation procedures.
The amount of PRTR-reported substances used in 2015 increased from 2014, which is due to an increased amount of chemical substances used in cleaning and painting processes as a result of the expansion of production volume.

Substitution of Standard Samples Used in Analytical Instruments

Until recently, the designated deleterious substances barium carbonate (BaCO3) and barium fluoride (BaF2) had been used in X-ray fluorescence spectrometers as sensitivity coefficient samples for determining the sensitivity coefficient for barium (Ba). In fiscal 2011, however, these were substituted with nontoxic barium sulfate (BaSO4) to reduce the chemical risk.
Since that eliminates the need to control the samples as deleterious substances, there are fewer restrictions on importing, exporting, or operating the systems, making the systems more convenient to use. Furthermore, it shortens our response time to customers. It also helps commercialize sensitivity coefficient samples.

Use of an Air Dust Blower That Uses No CFC Substitutes

Air dust blowers are used to remove debris and dust from instruments in instrument manufacturing, R&D and after-maintenance stages and many of them use CFC substitutes. Since CFC substitutes have an extremely high global warming potential, use of a specified amount of them needs to be reported to the government in Japan.
We are currently trying to use air dust blowers that contain carbon dioxide gas, instead of CFC substitutes, with a relatively smaller impact on the environment, especially at affiliated companies that often use air dust blowers for maintenance of instruments.
Use of this type of air dust blower also helps to reduce gas cylinder waste because cylinders can be reused by adding carbon dioxide repeatedly.

Pollution Measures

Air Quality Measurements (Sanjo Works)

SOx and NOx levels in exhaust gases emitted from boilers used in factories are monitored regularly with respect to Shimadzu standards, which are stricter than the standards in Japanese air pollution laws and Kyoto prefectural environmental regulations.
At the Sanjo Works, aging fuel oil-fired boilers and natural gas boilers are being replaced successively to help prevent air pollution and to reduce CO2 emissions. In FY 2014, all of the fuel oil-fired boilers have been replaced.

Water Quality Measurements (Sanjo Works)

Plant effluents are regularly measured with respect to Shimadzu standards, which are stricter than the standards in Japanese wastewater laws and Kyoto city wastewater regulations. In addition to regular measurements of each water quality parameter, the
Sanjo Works also utilizes a specialized monitor and intranet LAN to continuously monitor pH and TOC (total organic carbon) levels. Also, a rapid response system has been built to send email notification to the person in charge of the problem if the pH level of wastewater exceeds the Shimadzu standards.
