    Curbing the Amount of Waste, etc. Generated by the Sharp Group

    Sharp has been working to reduce waste and to recycle as much of it as possible in an effort to contribute to building a resource-recycling society. In fiscal 2017, the amount of waste, etc. generated by the Sharp Group increased by 10% (up 6,400 tons) compared to the previous fiscal year due to an increase in production volume. Meanwhile, the final landfill disposal rate decreased to 0.5% worldwide, thanks to company-wide, cross-organizational efforts including those by the SER Committee. In Japan, the final landfill disposal rate was 0.005%, marking the 17th consecutive year of achieving zero discharge to landfill* since fiscal 2001. Going forward, Sharp will strengthen waste reduction efforts at overseas bases and work to achieve zero discharge to landfill on a global scale.

    • Sharp defines “zero discharge to landfill” as a final landfill disposal rate of less than 0.5%.
      Final landfill disposal rate (%) = Amount of landfill disposal ÷ amount of waste, etc. generated × 100.

    Appropriate Storage and Management of PCB Wastes

    In Japan, Sharp properly stores and manages waste PCB (polychlorinated biphenyls) in accordance with the Act on Special Measures Concerning Promotion of Proper Treatment of PCB Wastes.

    Case Study

    Concentrating and Reducing the Amount of Waste Liquid from Washing to Reduce Industrial Waste

    Sharp’s Mie Plant (Taki District, Mie Prefecture) strives to generate less industrial waste from the manufacturing process for LCDs. The harmful gas generated in the production process is washed using chemical liquid so that it can be discharged in a harmless state outside of the plant. However, the chemical liquid used for cleaning (washing waste liquid) is emitted as industrial waste. In fiscal 2017, a portion of this industrial waste liquid was evaporated and concentrated at an on-site facility to drastically reduce its volume. This reduced the amount of waste by 192 tons a year.
