Managing Chemicals in the Production Process

Effective Management of Chemical Substances and Risk Management

Sharp meticulously controls chemical substances used at its plants. When introducing new chemical substances and new handling equipment, Sharp uses its own process assessment system*1 to evaluate the hazardousness of these substances and establish safety measures. To ensure employees’ safety and to minimize the environmental impact, employees handling these substances go through regular education and drills. They are also given regular health checks. Sharp also monitors and reports the release and transfer of chemical substances covered by the Japanese PRTR Act*2. Of these PRTR chemicals, 16 were handled in Japan and nine overseas*3 in quantities of 500 kg or more by one or more plants during fiscal 2017.

  • *1 An in-house system for preliminarily assessing and confirming the safety, environmental load, and other factors of chemical substances and their handling equipment.
  • *2 PRTR: Pollutant Release and Transfer Register. A system that mandates the collection and dissemination of information, such as the amount of harmful chemicals discharged and transferred.
  • *3 Sharp defines target substances based on laws in Japan.

Managing Environmental Load into Air and Water Areas

Sharp properly manages pollutants that affect air and water quality by establishing voluntary standards that are stricter than those set forth in laws and regulations and stricter than those agreed upon with local communities. It also actively conducts risk communication with local communities.

Case Study

Analyzing Plant Wastewater Samples (Fukuyama Plant)

Sharp’s Fukuyama Plant (Fukuyama, Hiroshima Prefecture) collects and analyzes plant wastewater in collaboration with local residents and Fukuyama city officials as part of its risk communication activities. The collected wastewater undergoes individual analyses by the three parties. The results are then shared and used for an exchange of views. This also provides Sharp the opportunity to foster good relations with all relevant parties.

Risk Management of Soil and Groundwater Pollution

Sharp set in-house standards in 1999 to minimize the risk of environmental pollution and accidents caused by chemical substances. It also strives to prevent such incidents from occurring by taking multi-layered leakage prevention measures at facilities that handle chemical substances. For plants where chlorine solvent contamination was found in the past, Sharp regularly notifies local government authorities and others of the cleanup progress.
