Waste and Recycling Measures
Waste substances generated from production sites, research laboratories, and major affiliated companies were separated by type and processed appropriately according to applicable laws and regulations. Due to continuing production increases, however, the overall volume is increasing. On the other hand, we continue to maintain a recycling rate of over 99 %
(99.6 %) by prioritizing reusing resources, such as by selling waste materials as a valuable resource. Furthermore, we monitor suppliers, including regular site inspections of waste management vendors, and have established and strictly implemented company regulations intended to ensure compliance with laws and regulations.

Reduction in Waste Boxes from Seta Works
Measures were implemented to reduce the amount of wood packing materials, used to transport parts or other items, that are generated as waste from Seta Works. Due to the limited space available for storing waste wood packing materials, a specialized container was previously used to have the materials removed by a waste management company as soon as they started accumulating, but the waste included many unflattened wooden crates that limited the container capacity.
Therefore, wood crates are broken down if possible and the bottom panels of wooden crates are reused as pallets for storage.
As a result, the wood waste is now collected only six times per month, whereas it was previously collected about 20 times per month, which required requesting a container pickup almost daily, also reducing the amount of waste and disposal costs.
In addition, the discarded wood crates are also converted to carbon, which is used as a soil amendment for Kyoto Prefecture gardens, for example, or donated for use during local festivals and so on.

Reusing Paper and Wood Materials
One environmental activity that everyone can participate in is the sorting of paper waste from offices and plants. Sorted and recovered paper is recycled into original notebooks for reuse by employees.
Having employees experience the benefits of environmental activities in such a tangible way helps employees become more conscious of environmental activities.
In FY 2016, Shimadzu began donating charcoal generated from Shimadzu wood waste to the olive orchard operated by the Setouchi Olive Foundation on Teshima, an island in Kagawa Prefecture, for use in amending the soil.
Currently, the charcoal is used to cultivate 1,000 olive trees in five olive orchards on the island.

The Handling of PCBs
Transformers, capacitors, and other devices containing highly toxic PCBs (polychlorinated biphenyls) are disposed of in accordance with the Japanese Act on Special Measures Concerning Promotion of Proper Treatment of PCB Wastes. (PCBs are particularly toxic to biological organisms because they are highly persistent and bioaccumulative.) Of the PCB waste materials owned by Shimadzu, Shimadzu started processing transformers and capacitors, which contain high PCB concentrations, in FY 2013 and will finish processing all the PCB waste within the time frame specified in the Japanese Act on Special Measures Concerning Promotion of Proper Treatment of PCB Wastes.
Meanwhile, Shimadzu Techno-Research Inc., a Shimadzu Group company, offers an easy method for analyzing the quantity of trace PCBs in two types of insulating oil. This measurement technology is able to quickly and inexpensively provide highly reliable measurement values and was even included in the Manual for Simplified Measurement of Trace PCBs in Insulating Oil (3rd edition), published by the Japanese Ministry of the Environment in May 2011.
Promoting Environmentally-Friendly Packaging
Shimadzu Logistics Service Corporation is engaged in a wide variety of activities for environmental conservation within its logistics activities. Of these, they are currently focused on switching to more environmentally-friendly packaging materials. Previously, heavy items were typically packed in crates made of lumber and plywood, but now they are switching to reinforced corrugated cardboard. The environmental benefits of switching to reinforced corrugated cardboard include conserving wood resources and reducing CO2 emissions during transport or incineration of the packaging materials. If wood materials are used, materials from Forest Stewardship Council-certified forests are recommended as a measure to promote biodiversity.
We intend to continue activities in the logistics field that help conserve the environment.
