Effective Management of Chemical Substances and Risk Management

Sharp meticulously controls chemical substances used at its production bases. 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 eight overseas*3 in quantities of 500 kg or more by one or more plants during fiscal 2018.

  • *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 (Nara Plant)

Sharp's Nara Plant (Yamato-Koriyama city) collects and analyzes plant wastewater in collaboration with Yamato-Koriyama city officials as part of its risk communication activities. The collected wastewater undergoes individual analyses. 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.

Wastewater sampling and analyses

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.

Managing Chemical Substances contained in Products

In order to reduce environmental impacts of its products and to comply with chemical substance regulations in countries around the world, Sharp has established in-house standards that take into consideration current standards as well as the trends towards regulations that may occur in the future, and works closely with its suppliers in managing the chemical substances in products. Sharp classifies the chemical substances to “banned substances (banned substances in product, banned substances depending on application)”, and “managed substances”. Sharp then manages the chemical substances contained in parts and materials (including raw materials, general parts, finished products, partially finished products, and secondary materials) used in Sharp products.

Management Categories of Chemical Substances

Category Description Remarks
Banned substance in the product Substances that cannot be used for any purpose
  • Substances with uses that are currently or foreseen to be regulated in the future for products through domestic/international laws and regulations and environmental labels
  • Substances that are well known to have a high environmental impact and that can be substituted
Banned substances depending on application Substances that can be used only for applications approved by Sharp (exceptional applications)
Managed substances Substances that can be identified in presence and/or quantity in a product
  • Substances that are required or may be required in the future by domestic/international laws and regulations or environmental labels to be disclosed when used in products
  • Substances that are required or may be required in the future by customers to be disclosed when used in products

Report on Chemical Substances Contained in the Product

In response to regulations prohibiting specific chemical substances to be included in products, Sharp confirms the presence of substances prohibited for use by having its suppliers submit a Substance Inclusion Report, which is a document attached to delivery specifications when new parts are adopted. Sharp also requests its suppliers to attach analytical data(test report) on the 10 restricted substances*1 of the EU's RoHS Directive*2. Sharp utilizes this information to make decisions on parts procurement.

Chemical Substance Content Survey

To comply with legal requirements that mandate the transmission and disclosure of information on chemical substances in countries around the world, such as the EU REACH regulations*3, Sharp utilizes an IT system to collect information, such as the contained amount of chemical substances in delivered parts and materials. Sharp also utilizes chemSHERPA*4, an information sharing scheme compliant with the international IEC 62474*5 standard, as a tool for collecting information. Sharp utilizes this information to tabulate statistics on chemical substances.

Evaluative Process for Newly Delivered Parts and Materials

  • *1 Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl (PBB), polybrominated diphenyl ether (PBDE), bis(2-ethylhexl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP).
  • *2 An EU directive on the “Restriction on the use of certain Hazardous Substances.”
  • *3 An EU regulation mandating the registration, evaluation, authorization, and restriction of chemical substances manufactured or imported into the EU.
  • *4 An information sharing scheme developed under the leadership of the Japanese Ministry of Economy, Trade and Industry for the purpose of efficiently communicating information on chemical substances in products over the entire supply chain.
  • *5 An international standard on the procedures and details of information sharing in the supply chain for products and components in the electrical and electronics industry containing chemical substances.
  • *6 Classifications according to uses of parts and materials to carry out appropriate evaluations.
